synallaxis is a genus of birds in the ovenbird family , furnariidae .

as of 2013 there were about 33 species , though a few belong to what is thought to be a species complex .

birds in this genus have mostly drab coloration and display secretive behavior , keeping ensconced in vegetation most of the time .

species can be difficult to distinguish from one another on the basis of their similar plumage ; however , they can often be told apart by their vocalizations , which can be quite distinctive .

synallaxis

i found this song very similar to the records of synallaxis albilora , but the area is far away for that . . . do you think that it is synallaxis gujanensis ?
the bahia spinetail (
synallaxis cinerea
) is a species of bird in the family furnariidae .
the apurímac spinetail (
synallaxis courseni
) is a species of bird in the family furnariidae .

as trusted .
option a is the least convenient , in my opinion . synallaxis is already very diverse and heterogeneous ( it already includes the former genera siptornopsis and gyalophylax , for example ) ; inclusion of certhiaxis and schoeniophylax within synallaxis will increase this heterogeneity even more . schoeniophylax was previously merged within synallaxis by vaurie ( 1980 ) , but this treatment did not gain general acceptance . moreover , merging certhiaxis into synallaxis creates further nomenclatorial problems as the yellow - chinned spinetail , s . cinnamomeus ( gmelin 1788 ) , would become homonym with the stripe - breasted spinetail s . cinnamomea lafresnaye 1843 .
finally , bauernfeind et al . ( 2014 ) concluded “if the amnh syntypes attributable to synallaxis cinereus wied include amnh 6813 , in agreement with the interpretations by allen ( 1889 ) and lecroy & sloss ( 2000 ) , then the designation of amnh 6813 as the lectotype for this taxon ( whitney & pacheco 2001 : 35 ) is valid . in such circumstances , we respect their judgment in formally considering synallaxis whitneyi pacheco & gonzaga a junior subjective synonym of synallaxis cinerea wied .

incorporates poecilurus , siptornopsis and gyalophylax , all of which have been found to be morphologically and genetically # r inseparable from synallaxis . see also mazaria ( above ) .
: synallaxis propinqua has been always included in the genus synallaxis , classification that nobody has questioned since the morphology and habits of this species seem typical of members of this genus . however , in the comprehensive molecular phylogeny of derryberry et al . ( 2011 ) , propinqua appears as sister to schoeniophylax phryganophilus , and together they form the sister group of a clade including certhiaxis and other synallaxis . lack of statistical support for the relevant nodes prevented making taxonomic rearrangements before the surprising relationship could be confirmed .

option b . transferring propinqua from synallaxis to schoeniophylax is less disrupting than a regarding nomenclatorial changes , although the white - bellied spinetail would become schoeniophylax propinquus , to match the masculine genus ( david & gosselin 2002 ) . the drawback of this option is that the resultant genus would combine two species that are phenotypically very distinct , with no other transitional species that fills the phenotypic gap between them . the resultant genus would be difficult to characterize other than listing the sum of characteristics of both species . also note that these sister species are not particularly closely related according to divergence time estimates . on the other hand , note that the argument regarding phenotypic differences could be turned around in support of option b by arguing that the new taxonomy would help showing a relationship that is otherwise difficult to recognize .
the hoary - throated spinetail ( synallaxis kollari ) is a small , long - tailed bird with a bright reddish - brown body , a reddish - brown tail , yellowish - brown to whitish underparts , and distinctive head markings . the top of the head is grey - brown , with a reddish - brown stripe over the eye , and the cheeks are grey with a white stripe . the white throat is speckled black , giving this species its common name , and the lower throat is black ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 ) . the tips of the flight feathers are a darker dusky brown , and the beak and legs are bluish - grey . the male and female hoary - throated spinetail are similar in appearance , but no descriptions of the juvenile are available ( 2 ) ( 3 ) . the song of this species consists of two short notes , repeated at one - second intervals , with the first note higher pitched than the second ( 2 ) ( 3 ) ( 4 ) ( 6 ) .

this species is endangered because it has a very small range , in which the extent , area and quality of habitat are declining . the population is probably also very small , fragmented and declining because of the threats to its habitat ( collar
the population is estimated to number 1 , 000 - 2 , 499 individuals based on an assessment of known records , descriptions of abundance and range size . this is consistent with recorded population density estimates for congeners or close relatives with a similar body size , and the fact that only a proportion of the estimated extent of occurrence is likely to be occupied . this estimate is equivalent to 667 - 1 , 666 mature individuals , rounded here to 600 - 1 , 700 mature individuals . trend justification : a slow and continuing population decline is suspected , owing to rates of habitat loss .
it inhabits scrub and dense undergrowth with scattered small trees , at elevations of 1 , 800 - 2 , 900 m . usually encountered in pairs , birds forage for insects in moss clumps and along vines and branches . juveniles and an active nest have been collected in may ( franke and salinas 2000 , remsen and sharpe 2016 )
dense undergrowth habitat within its range is severely threatened by cattle - grazing and clearance for farm expansion .

this species , which has a very small occupied range which is severely fragmented , and declining in extent and quality , has been uplisted to critically endangered because a model of future deforestation in the amazon basin predicts that its population will decline extremely rapidly over the next three generations as land is cleared for cattle ranching and soy production , facilitated by expansion of the road network .
: this is an issue of nomenclature that if passed would replace our current species epithet with another .
: bauernfeind et al . ( 2014 ) re - examined the case and concluded that cinerea is the correct name for bahia spinetail .
as a consequence they suggested the provisions of art . 72 . 7 would apply and both the nominal taxa would have the same name - bearing type .
the rationale for this new interpretation was based on their analysis of wied’s german text , with wied’s intention .
however , bauernfeind et al . ( 2014 ) considered such express intention in wied’s text as not convincing .
( red - headed ) did not truly characterize the taxon – and not for the reason that the species - group name had already been in use within the same genus ( which it actually was not ) .

little is known about the biology of the hoary - throated spinetail . like other members of the furnariidae family , it is likely to feed on invertebrates such as insects , taking prey in dense undergrowth , near the ground ( 2 ) ( 3 ) ( 6 ) . it probably feeds alone or in pairs ( 2 ) ( 3 ) ( 6 ) , and is presumed to be monogamous ( 2 ) , although very little is known about its life history . the only records of the hoary - throated spinetail’s breeding behaviour are of incomplete nests , one of which was found in july and was believed to have been constructed by both the male and female . located in dense vegetation , it was cup - shaped and built from twigs ( 2 ) ( 3 ) ( 4 ) ( 8 ) . however , it is likely that , as in related species , the completed nest would be a dome of sticks with a cover , a tubular entrance , and very little lining ( 3 ) ( 8 ) .
the hoary - throated spinetail is known only from a few sites along rivers in northern roraima , brazil , and in adjacent guyana ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 ) . it has a highly fragmented range , with patches of suitable habitat thought to total no more than 206 square kilometres ( 4 ) ( 7 ) .
the hoary - throated spinetail appears to be restricted to a narrow strip , under 500 metres wide , of seasonally flooded riverine forest . these forests are surrounded by savanna , and have an understorey of dense thickets and vines ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 ) .
the hoary - throated spinetail is classified as critically endangered ( cr ) on the iucn red list ( 1 ) .
the main threat to the hoary - throated spinetail is the rapid conversion of its habitat to rice plantations , with the burning of vegetation potentially posing a further problem ( 3 ) ( 4 ) ( 7 ) . although still thought to be relatively common where it occurs , the species is restricted to a tiny and fragmented range , none of which is officially protected , and is believed to number only around 5 , 000 or so individuals ( 2 ) ( 3 ) ( 4 ) ( 7 ) . with so little known about the hoary - throated spinetail , there is also the potential for unidentified threats to take a toll on the species before they are recognised ( 9 ) .
although not occurring within officially protected areas , nearly 60 percent of the hoary - throated spinetail’s habitat is inside indigenous reserves , where the indigenous people have a much better record of maintaining the ecosystem than non - indigenous peoples . most rice production in roraima is carried out illegally by non - indigenous people on indigenous land , but in some areas , such as são marcos indigenous reserve , rice producers have been evicted , hopefully giving renewed hope for the wildlife there ( 3 ) ( 4 ) ( 7 ) . producers should also have been evicted from raposa - serra do sol following its legalisation in 2005 , but this is not yet known to have occurred ( 3 ) ( 7 ) .
due to a lack of data on the hoary - throated spinetail , the species was taken off brazil’s list of threatened species , although it is hoped that it will be put back on in the future ( 3 ) ( 7 ) . priorities for the conservation of the hoary - throated spinetail include improving knowledge about its ecology and behaviour , and taking measures to protect its habitat , including assessing the impact of recent fires , supporting indigenous peoples seeking to prevent habitat destruction within their reserves , and increasing the number of officially protected areas within roraima ( 3 ) ( 4 ) ( 9 ) ( 10 ) .

interactions between species can promote evolutionary divergence of ecological traits and social signals 1 , 2 , a process widely assumed to generate species differences in adaptive radiation 3 , 4 , 5 . however , an alternative view is that lineages typically interact when relatively old 6 , by which time selection for divergence is weak 7 , 8 and potentially exceeded by convergent selection acting on traits mediating interspecific competition 9 . few studies have tested these contrasting predictions across large radiations , or by controlling for evolutionary time . thus the role of species interactions in driving broad - scale patterns of trait divergence is unclear 10 . here we use phylogenetic estimates of divergence times to show that increased trait differences among coexisting lineages of ovenbirds ( furnariidae ) are explained by their greater evolutionary age in relation to non - interacting lineages , and that—when these temporal biases are accounted for—the only significant effect of coexistence is convergence in a social signal ( song ) . our results conflict with the conventional view that coexistence promotes trait divergence among co - occurring organisms at macroevolutionary scales , and instead provide evidence that species interactions can drive phenotypic convergence across entire radiations , a pattern generally concealed by biases in age .

during adaptive radiations , species that share geographic ranges ( in sympatry ) have higher levels of character divergence than those that are geographically isolated ( in allopatry ) . the traditional explanation invokes species interactions : selection favours greater divergence when there is direct competition for the same ecological niche . this has never been robustly tested at broader macroevolutionary scales , however . these authors present an extensive assessment of phenotypic divergence in the context of evolutionary time , focusing on ovenbirds , one of the most diverse families of birds in the world . estimates of divergence in multiple genes and traits across a radiation of 350 ovenbird lineages show that the ecological or reproductive traits of coexisting species are no more divergent than those of non - interacting species , instead providing evidence that species interactions can drive widespread phenotypic convergence .

: i recently revisited the problem with and enhanced molecular dataset including : 1 ) the mitochondrial nd2 gene ( already analyzed by derryberry et al . 2011 ) , 2 ) two introns from the z chromosome ( aco1 and musk , analyzed together ) ; 3 ) introns 5 - 11 of the g3pdh gene ( and intervening exonic sequences ) ; and 4 ) introns 5 and 7 of the beta fibrinogen gene fgb ( claramunt 2014 ) .
( bootstrap support : g3pdh : 51 , nd2 : 86 , z - linked : 96 , fgb : 100 ) . there was less agreement regarding the position of this pair of species within the larger clade , but g3pdh and z - linked genes showed
but with low support ( 73 ) , and fgb did not resolve basal relationships .
was also found when genes were analyzed jointly either by concatenation ( ml bootstrap : 92 ) and using a species - tree ( star ) method that accounts for potential incomplete lineage sorting .
given these results , the classification needs to be changed . among several options , i opted for describing a new genus for propinqua , which i named mazaria , honoring our dear juan mazar - barnett .
c : place propinqua in its own genus mazaria , the option advocated in this proposal .
option c , is minimally disrupting other than introducing a new generic name . the disadvantage of option c is the creation of a monotypic genus that is not informative regarding relationships and redundant in the sense that the genus mazaria and the species mazaria propinqua would contain exactly the same taxon . on the other hand , monotypic taxa cannot be completely avoided in general , and in this case , the monotypic genus would help represent the phenotypic distinction of propinqua in relation to its sister species and highlight that theses two species are not particularly closely and have long history of independent evolution .
at the end , i think that option c would result in a classification that is more in consonance with traditional conceptualizations of what an avian genus is ( mayr 1999 ) and therefore i recommend recognizing the new genus mazaria for propinqua ( a yes on this proposal ) .

i have been aware of this one for several years and strongly concur with santiago on all of this .
the classification must be changed , and option c is clearly the best , in my view . ”
: “yes . in the most mayrian sense of a genus , i endorse the placement of propinqua in mazaria . vocally and phenotypically it does sound - look like a schoeniophylax - certhiaxis . however , my subjective heart is pleased to see this new genus dedicated to the memory of juancito . ”
“i much prefer option b , in this case , for the primary reason santiago recognized : one genus for these two clarifies and highlights their sister relationship within this huge family .
they uniquely share a harsh , grating quality in songs and calls that is practically unique in the part of the phylogeny presented in this proposal , and they both occasionally perform fairly complex duets .
some of the others in this part of the tree might be considered to give duets , in that the members of the pair sometimes vocalize in tandem ( e . g . ,
, also somewhat “harsh and grating
) , but they are not two - parted , synchronized vocalizations like those occasionally delivered by pairs of schoeniophylax . ( i’ve never seen “
in life , and it’s been so long since i’ve seen stictothorax that i can’t remember much about its vocalizations — so i don’t know about possible dueting in that clade . ) ”
“the erection of a monotypic genus should almost always be considered quite disruptive , just as is the lumping of phenotypically distinctive clades / species traditionally considered separate genera into related genera , always in the pursuit of avoiding paraphyly .
“yes . i definitely prefer diagnosable genera , even if monotypic ; the only real alternative , including both in certhiaxis , produces an undiagnosable soup . ”
i prefer c , the option that keeps a distinctive genus for this taxon . ”
moreover , the continued movement for making anything that looks different and / or has a relatively long branch in the tree as a monotypic genus is undermining the purpose of nomenclature , i . e . , effective communication and conveying relationships . ”
: “no . i largely agree with bret , and embracing the subjectivity noted by mayr i subjectively prefer classifications that are informative about relationships over the recognition of monotypic genera except when dealing with real oddballs . subjectively , admittedly , i think this is not the case here . ”
: “yes – inclusion into schoeniophylax is not palatable to me , that is such a distinctive bird . given that this pair is not all that closely related to each other , i am ok with the creation of a monotypic genus and happy that it is called mazaria . ”
: “i am a little surprised that this proposal met any opposition , so i am adding some extra comments .
creates an indefensible morphological grouping in addition to the two lineages being separated as long ago as many current genera .
song as harsh and grating , but rather , in my subjective opinion , amazingly rich and melodious , at least compared to any other spinetail . ”
i’ve waffled back and forth on this one , sharing some of the concerns raised by bret , mark and daniel regarding erecting a monotypic genus for a bird that is not that distinctive phenotypically or vocally from other members of the larger clade .
that , in my opinion , outweighs any informative gains of recognizing the sister status of the two species by placing them in the same genus .
to be “rich and melodious” , having a liquid , gurgling tonal quality that is difficult to describe , and , which is unique within the synallaxines .
would result in a tiny , amorphous genus that would defy any attempts to produce a coherent diagnosis , solely to make clear that the two species are sister taxa . ”
population justification : the global population size has not been quantified , but this species is described as ' fairly common ' ( stotz et al . ( 1996 ) .
trend justification : this species is suspected to lose 28 . 6 - 29 . 1 % of suitable habitat within its distribution over three generations ( 11 years ) based on a model of amazonian deforestation ( soares - filho et al . 2006 , bird et al . 2011 ) . given the susceptibility of the species to fragmentation and / or edge effects , it is therefore suspected to decline by a rate approaching 30 % over three generations .
population justification : the population is estimated to number 250 - 999 mature individuals based on an assessment of known records , descriptions of abundance and range size . this is consistent with recorded population density estimates for congeners or close relatives with a similar body size , and the fact that only a proportion of the estimated extent of occurrence is likely to be occupied . this estimate is equivalent to 375 - 1 , 499 individuals in total , rounded here to 350 - 1 , 500 individuals .
trend justification : a rapid ongoing population decline is suspected owing to rates of habitat loss .

however , the slaty spinetail constructs a bulky spherical stick nest 36x43 cm in size , with a long tubular entrance , 0 . 4–4 . 5 m high in a shrub or vine covered tree . it lays two or three greenish white eggs .
this species is a widespread and common resident breeder in lowlands and up to 1500 m altitude in a range of scrubby habitats , including second growth , road and river edges , and overgrown pasture .
the spinetail mobula ray has a pelagic lifestyle and has been observed both alone and in groups . it feeds on zooplankton by filtering sea water .
its natural habitats are subtropical or tropical moist lowland forests , subtropical or tropical moist shrubland , and plantations .
the necklaced spinetail is a fairly common bird within its rather restricted range . the total number of birds has not been estimated but the population trend seems to be stable so the international union for conservation of nature has assessed its conservation status as being of
least concern

the taxonomic update for 2013 is now complete in ebird . the names and sequence have been changed and ebird records have been updated in cases of splits and lumps . this update includes updates since august 2012 to the north american classification committee and south american classification committee , including several splits detailed below . in the united states and canada the most significant change was the split of sage sparrow into bell’s sparrow and sagebrush sparrow . in central and south america , immaculate antbird was split into zeledon’s antbird and blue - lored antbird . in addition , there were some changes to scientific names and sequence of shorebirds , mimidae ( mockingbirds and thrashers ) , and several other groups of birds . elsewhere in the world , a large number of taxa were split in southeast and south asia ( especially india ) , along with a few in africa , europe , and australasia .
the full taxonomy can be downloaded . also , we have a version of the full taxonomy with changes in common name , scientific name , and new additions highlighted ; download that here . for those proficient with spreadsheets , this may be the easiest way to review the changes .
a full summary of the taxonomic changes is below . since this is a long article , here is a short index :
when the taxonomy is updated in ebird , many of the changes are fairly simple to implement . when a common name changes , a scientific name changes , or when the taxonomic sequence is revised , those changes roll through and start appearing in ebird output fairly quickly . keeping track of name changes is a challenge , and avibase is one of the best ways to do so . just type any bird name in avibase and avibase will show you what the history of that name is , and–if it differs from ebird–it will show what the ebird equivalent is for that name . try it for louisiana heron , for example .

this pheasant is protected by law , although the law is poorly enforced on the island of palawan . the survival of this bird now depends on its ability to adapt to living in the scrub and felled forest , because of the decline of the tropical forest on palawan . this pheasant breeds well in captivity .
we placed palawan , calamian islands , and cuyo islands into a single ecoregion , the palawan rain forests [ im0143 ] . palawan has closer zoogeographic affinities to borneo .
like other pheasants , palawan peacock - pheasants are sexually dimorphic - males and females differ in colour . males are predominantly metallic blue , green and black , females a less conspicuous brown . they are ground - dwelling and prefer dense vegetation , moving quietly through the undergrowth . palawan peacock - pheasants live only on the island of palawan in the southern philippines . palawan has suffered extensive deforestation and the whole island is now designated as a biosphere reserve , although protecting it is very difficult .
previously considered endangerd , the level of threat facing the palawan peacock - pheasant has been downgraded in recent years . however , the pheasants have also been trapped for the pet trade and are hunted for meat , and much of their remaining forest habitat is leased to logging companies . as a result , the wild population is still declining .
, this is probably atypical as peacock - pheasants are as a rule monogamous with males participating in nest defense and chick rearing . the
palawan peacock - pheasant populations are undergoing a rapid decline as a result of habitat destruction , hunting and trade ( 5 ) . lowland forests on palawan have been widely cleared , and although coastal forest remains relatively extensive in the south , illegal logging there is thought to continue ( 5 ) ( 9 ) . furthermore , logging and mining concessions have been granted for almost all remaining forest on the island ( 5 ) . by the 1960s , direct exploitation of the palawan peacock - pheasant was also a growing concern , with large numbers being hunted for food and trapped for live trade to zoos and aviculture enthusiasts , but exports were much reduced by the late 1980s . nevertheless , the bird continues to be hunted for food and some trade ( 5 ) ( 9 ) .
we call it palawan - pfaufasan in german usually , not naopleonpfaufasan . . .
numbers of palawan peacock pheasants are rapidly declining because of habitat destruction , hunting and trade . illegal logging is a real problem on palawan , and approval for logging and mining has been given for the rest of the island . this means that even more of the lowland forests which are home to these birds are at risk .

the palawan peacock pheasant is a ground dwelling bird . the male is very colorful like the peacocks we are all familiar with but is considerably smaller . he also likes to strut and display for the female just like the larger ones . his tail is adorned with blue - green eye spots encircled by rings of black and gray . the female is mostly brown with white on her face and throat . they are related to turkeys , grouse , quail , guineafowl and curassows . our male and female produced two chicks in july 2013 pictured above .
hunting and the wild pet trade are also significant threats in palawan . leopard cats have been hunted for their pelts and are sold when kittens as pets ( heaney and regalado 1998 ) . the palawan binturong is hunted for meat and as pets , and the pangolin is hunted for its hide ( quinnell and balmford 1988 ) . the palawan peacock - pheasant ( dickinson et al . 1991 ; collar et al . 1999 ) , blue - headed racquet - tail ( collar et al . 1999 ) , philippine cockatoos ( cacatua haematuropygia ) , and blue - naped parrots ( tanygnathus lucionensis ) ( quinnell and balmford 1988 ) apparently are suffering greatly from the pet trade . the final destination for these birds often is the united states ( quinnell and balmford 1988 ) .
kimball , rebecca t . ; braun , edward l . ; ligon , j . david ; lucchini , vittorio & randi , ettore ( 2001 ) : a molecular phylogeny of the peacock - pheasants ( galliformes :
there are many endemic mammals in palawan , but nearly all the genera ( 96 percent ) are also found in borneo . of twenty - five indigenous nonvolant mammal species , eleven ( 44 percent ) are endemic to palawan , and the remainder are shared with borneo . therefore , the greater palawan region is rightly considered part of the sunda shelf bioregion rather than that of the philippines . the large number of endemic species but few endemic genera of palawan are consistent with a separation of borneo and palawan of approximately 160 , 000 ( since the middle pleistocene ) ( heaney 1986 ) . there are fifteen endemic or near - endemic mammals in greater palawan ( table 1 ) .
endemic to the island of palawan in the philippines , for which it gets its common name ( 4 ) ( 5 ) .
this is a palawan scops owl , an uncommon mainland palawan endemic ranging in forest and forest edge . just like a lot of the philippines’ owls , this one is poorly - known and few documentations about the breeding , behavior and ecology of this species exist .
this species is endemic to the island of palawan in the philippines , where it lives , feeds and nests on the forest floor .
the channel between palawan and borneo is about 145 m deep . during the middle pleistocene , sea levels were 160 m lower than today , and the islands were connected . during the last ice age ( late pleistocene ) , sea level was approximately 120 m below current levels , and palawan was separated from ice age borneo by a narrow channel . palawan has always remained separated from the rest of the philippines . palawan is long and narrow , consisting of a steep mountain range whose highest point is 2 , 085 m ( mt . mantalingajan ) . more than 45 percent of palawan consists of mountains with slopes greater than 30 percent ( davis et al . 1995 ) .
the palawan scops owl prefers to stay in bamboo thickets and dense understory and often quite close to the ground . it is the only small eared owl in palawan but sometimes the bigger and more rufous , small - island specialist mantanani scops owl can also occur at times .
male 50 cm , female 40 cm . dark peacock - pheasant . sexually dimorphic . male has pointed , dark crest , bare red orbital skin , white supercilium and patch on ear - coverts . black rest of head and underparts . shiny blue - green mantle , wing - coverts and tertials with darker feather - bases . black back , rump and tail , speckled buff with two rows of large green - blue ocelli on tail . female is smaller , duller , generally brown with indistinct buff markings and off - white throat , ear - coverts and supercilium .
several of palawan ' s endemic mammals are considered threatened . three endemic mammal species are considered endangered , including the calamian deer , a sunda tree squirrel ( sundasciurus juvencus ) ( recommended for delisting ; heaney et al . 1998 ) , and the palawan rat ( palawanomys furvus ) , which was collected only four times in 1962 . a subspecies of mouse deer , the balabac chevrotain ( tragulus napu nigricans ) , which is confined to balabac island , is also considered endangered . five endemic mammal species are considered vulnerable , including acerodon leucotis , the palawan treeshrew ( tupaia palawanensis ) , the palawan stink badger ( mydaus marchei ) , the palawan binturong ( arctictis binturong whitei ) , and a sunda tree squirrel ( sundasciurus rabori ) ( iucn 2000 ) .
the palawan peacock - pheasant is notable for the male’s impressive crest and vibrant plumage , which is glossy black with a dazzling metallic green - blue lustre on the crest , crown , neck , mantle and wings ( 4 ) ( 5 ) . the long tail is black , finely speckled with buff and adorned with two rows of large and conspicuous green - blue ocelli ( eye - shaped spots ) . the face has a distinctive pattern of black and white , with bare red skin around the eyes ( 5 ) . while males bear these lustrous colours and striking ocelli , which they flaunt in elaborate courtship displays to attract mates , females are rather drab in comparison ( 6 ) . their brown plumage , with scattered buff markings ( 2 ) , helps camouflage and conceal the females while they incubate their eggs and brood their young ( 6 ) .
palawan ' s forests are of low commercial value because of the small number of dipterocarps , and until the last twenty years palawan ' s forests were ignored in favor of the more valuable forests of luzon and mindanao . government logging regulations setting guidelines for minimum diameter , minimum rotation length , and replanting have been largely ignored ( quinnell and balmford 1988 ) .
description location and general description this ecoregion includes the island palawan plus balabac , ursula island , and the calamian group . palawan itself is the sixth largest of the philippine islands . the climate of the ecoregion is tropical wet ( national geographic society 1999 ) . in northwest palawan , a dry season lasts from november to may while the wet season lasts from june to october ; the rest of the island experiences a short , one - to three - month dry season . the east coast becomes progressively drier than the west coast from north to south ( davis et al . 1995 ) .

palawan is one of the major destinations for birding in the philippines . it is distinctively different from the rest of the country in terms of avian diversity . the avifauna here is similar to that of mainland asia with overlapping species like black - headed bulbul , ashy tailorbird , asian fairy bluebird , chestnut - breasted malkoha among others . the island of palawan is a long strip of land that has several endemics as well , such as this stunning yellow - throated leafbird .
biodiversity features relative to the size of palawan , the ecoregion contains a rich fauna , including several groups that are not found in the rest of the philippines ( carnivores , pangolins , porcupines , and some insectivores ) ( heaney 1986 ) .
currently , palawan ' s mineral wealth ( chromite , copper , iron , manganese , mercury , and nickel ) has not been extensively exploited , but the possible future extraction of these minerals represents a potential threat ( quinnell and balmford 1988 ) .
palawan represents a bridge between the sunda shelf and philippine bioregions and contains faunal elements from both , as well as it own unique elements . this ecoregion , though more intact than any other region in the philippines , is under great pressure from logging interests .
this yellow - throated leafbird is one of two endemic leafbirds in the philippines . this leafbird prefers the canopy of trees , often seen feeding with mixed flocks composed of hair - crested and ashy drongos , fiery minivet , palawan tit , and lovely sunbird .
because of a generally high population density in other parts of the philippines , large numbers of shifting cultivators ( kaingineros ) are attracted to palawan to eke out a living on the hillsides of the island , and their cumulative impact is enormous ( quinnell and balmford 1988 ) .
the entire island of palawan was made a game reserve in 1983 , making hunting illegal . however illegal hunting is hard to control and even harder to enforce . zoos worldwide are contributing to managed breeding programmes for the birds , but the wild population remains very much at risk .
limestone forests are found on the islets surrounding palawan and over large areas in the southern portions of the island . represented are euphorbia trigona , aglaia argentea , and antidesma , drypetes , gomphandra , sterculia , pleomele , and begonia spp . ( davis et al . 1995 ) .
all of palawan was declared a fauna and flora watershed reserve , and this includes a variety of protected areas , including national parks , wilderness areas , experimental forests , forest research reserves , game refuges , wildlife sanctuaries , museum reservations and research sites , tourist zones , and marine reserves .
a total of 1 , 522 ( davis et al . 1995 ) to 1 , 672 ( quinnell and balmford 1988 ) vascular plants have been identified on palawan , and it is estimated that more than 2 , 000 species are present on the island . as detailed earlier , palawan has an extremely diverse range of vegetation types for the philippines . a small number of dipterocarps , an important timber tree group , are present on the island , as well as a variety of medicinal plants used by ethnic tribes and plants used in ceremony and as ornamentals ( davis et al . 1995 ) .
current status almost all of the philippines was once completely forested ( dickinson et al . 1991 ) . as of 1988 , palawan contained 7 , 410 km2 ( 54 percent ) of total forest remaining ( ssc 1988 ) . at the time this was the highest percentage of any of the philippines ' large islands .
recent reports in the international press indicate ( and have been confirmed , l . heaney , pers . comm . , 2000 ) that the situation in palawan has stabilized , that large - scale logging has been halted , and that a balance is being achieved between economic development and conservation ; future monitoring will determine whether this is remains true .
victoria peak , in south - central palawan , contains the largest region of ultramafic forest on the island . although many of the ultramafic tree species are shared with semi - deciduous forest , several species , including scaevola micrantha , brackenridgea palustris var . foxworthi , exocarpus latifolius , and phyllanthus lamprophyllus are believed to be heavy metal indicators ( davis et al . 1995 ) .
this species ' s population was previously estimated at fewer than 10 , 000 mature individuals by mcgowan and garson ( 1995 ) . densities recently calculated in puerto princesa subterranean river national park suggest that the figure given by mcgowan and garson ( 1995 ) is likely to be an underestimate , based on estimated forest coverage on palawan . however , the latest density estimates are unlikely be representative of the whole island . with this in mind , the species ' s population is conservatively placed in the band 20 , 000 - 49 , 999 individuals . trend justification : logging and clearance of lowland forest has been extensive on palawan and continues , with many areas falling within mining designations . hunting pressure is also severe in places . as a result the species is suspected to be declining rapidly .
vegetation types on palawan are diverse and include beach forest , tropical lowland evergreen dipterocarp rain forest , lowland semi - deciduous forest , montane forest , and ultramafic and limestone forest . beach forest merges with other forest types away from the coast and includes calophyllum inophyllum , canarium asperum var . asperum , pometia pinnata , palaquium dubardii , and ficus spp . ( davis et al . 1995 ) .
this is a falcated ground - babbler , one of the most gorgeous and most sought - after palawan endemics . this lowland , uncommon and very secretive skulker prefers to stay near the ground in dense foliage , turning leaves and dried litter in search of small invertebrates and grubs . this endemic has a loud , conspicuous song consisting of melodious whistles and babbling notes will often respond to playback . hear it for yourself . 🙂
the lowland evergreen dipterocarp rain forest , which naturally occupies 31 percent of the island , is dominated by agalai spp . , dipterocarpus gracilis , d . grandiflorus , ficus spp . , tristania spp . , exocarpus latifolius , and swintonia foxworthyi . sygium spp . , dracontomelon dao , and pongamia pinnata are emergent . lianas and cycads are common . in southern palawan , a casuarina sp . dominates in the lowland forests ( davis et al . 1995 ) .
allocate greater resources towards more effective control of hunting in palawan forests and initiate conservation awareness campaigns amongst forest product collectors . continue surveys to assess distribution , status and habitat requirements in remaining lowland forests and secondary habitats , particularly south of brooke ' s point , on the slopes of mt victoria and in remaining forests in the north . formally protect forests at iwahig . support the proposed extension of puerto princesa subterranean river national park and promote the development of captive - breeding programmes .
, where it occurs on palawan ( birdlife international 2001 ) . it is known from c . 20 localities throughout the island , with records from at least 11 since 1980 . local reports suggest that it has a wider distribution . in the early 1970s , despite local extinctions , it was not considered particularly rare . in 1995 , its fragmented population was estimated to number fewer than 10 , 000 mature individuals ( mcgowan and garson 1995 ) ; however , more recent density estimates from puerto princesa subterranean river national park ( mallari
justification of ecoregion delineation mackinnon ( 1997 ) identified seven subunits in the philippines , and the philippine biodiversity action plan ( philippine bap 1997 ) demarcated fifteen biogeographic units . udvardy ( 1975 ) identified the philippines as a single biogeographic province . we delineated nine ecoregions in the philippine islands , including palawan . we deviated from udvardy ( 1975 ) , mackinnon ( 1997 ) , stattersfield et al . ( 1998 ) , and the philippine bap ( 1997 ) to varying degrees and based our delineation of the philippine ecoregions on heaney ( 1993 ) .
the philippines only has one species of cockatoo : the philippine or red - vented cockatoo . it used to be widespread and ranged in the major islands of the philippines but the rampant poaching for the illegal pet trade as well as habitat destruction lead to its decline and is now declared as critically endangered . currently , the best place to see the philippine cockatoos in the wild is in the island of palawan , in rasa island . access to the island is restricted and is managed by one of the philippines’ top conservation organizations , the katala foundation ( urltoken )
types and severity of threats habitat destruction is the main threat to biodiversity in the philippines , and palawan , though currently in better condition , is no different . logging and shifting cultivation ( kaingin ) are cited as the primary forces of habitat conversion . logging takes many forms , from industrial scale to smaller - scale operations that use water buffalo to haul logs out of the forest . mangroves are used locally for firewood , dyes , and tannins ( davis et al . 1995 ) , and they are sometimes removed to make way for fishponds ( quinnell and balmford 1988 ) .

despite evidence that its population may be larger than previously estimated , this species still qualifies as vulnerable because it is suspected to be undergoing a rapid decline as a result of habitat destruction , hunting and capture for trade .
. 2011 ) suggest that this was an underestimate . as a result of the latest density estimates ( mallari
. 2011 ) , the population is conservatively estimated at fewer than 50 , 000 mature individuals . the species , however , is still thought to be declining .
it mainly inhabits primary and secondary forest on flat and rolling terrain , up to c . 800 m , occasionally occurring almost up to mossy forest and in
- dominated dwarf forest on serpentine rock . surveys in puerto princesa subterranean river national park found evidence that the species shows a strong preference for old growth forest over advanced secondary growth , which in turn appears to be preferred over early secondary growth , with none recorded in cultivation ( mallari
. 2011 ) . logging and mining concessions have been granted for almost all remaining forest on the island . as of december 2008 , nine small scale mining permits had already been issued and there were 354 mining applications pending , covering 6 , 510 km
. 2011 ) . illegal logging is thought to persist in the remaining extensive forest of the south . forest at iwahig penal colony , regarded as a key site , may be threatened by plans to mine chromite . by the late 1960s , the species was being extensively hunted and trapped in large numbers for live trade , but exports were much reduced by the late 1980s . in the mid - 1990s , it was heavily hunted adjacent to puerto princesa subterranean river national park , and this protected area is still subjected to pressures on habitats , including agricultural encroachment and the harvesting of non - timber forest products ( mallari

the eastern half of the island is in a rain shadow and contains moist semi - deciduous forests . soils are thin on the steeper slopes and support medium - sized trees ( up to 15 m tall ) , which shed their leaves during the march - may dry season . the rainy season is june - july . common tree species include pterocymbium tinctorium , pterospermum diversifolium , hymenodictyon spp . , and garuga floribunda ( davis et al . 1995 ) .
montane forests , found between 800 and 1 , 500 m , are dominated by tristania spp . , casuarina spp . , swietenia foxworthyi , and litsea spp . in the lower elevations . upper montane forest trees include agathis philippinensis , dacrydium pectinatum , podocarpus polystachyus , gnetum latifolium , cycas wadei , cinnamomum rupestre , nepenthes philippinensis , and angiopteris spp . ( davis et al . 1995 ) .
family species pteropodidae acerodon leucotis * cervidae axis calamianensis * sciuridae sundasciurus steerii * sciuridae sundasciurus moellendorfi * sciuridae sundasciurus rabori * sciuridae hylopetes nigripes * muridae chiropodomys calamianensis * muridae maxomys panglima * muridae palawanomys furvus * hystricidae hystrix pumila * sorcidae crocidura palawanensis * muridae haeromys sp . a * sciuridae sundasciurus hoogstraali * sciuridae sundasciurus juvencus * tupaiidae tupaia palawanensis *
the calamian deer ( axis calamianensis ) is found only in the calamian islands , where it survives in low densities on busuanga , calauit , and culion islands . the only protected area for this species was established to protect free - ranging african ungulates on calauit island ( wemmer 1998 ) .
the critically endangered philippine crocodile ( crocodylus mindorensis ) was historically found on the islands of luzon , mindoro , masbate , samar , jolo , negros , busuanga , and mindanao . busuanga contains one of the only remaining populations ( others are found on mindoro , negros , and mindanao ) . whereas the decline of the species was initially driven by overexploitation , habitat loss and human persecution are now the principal threats to the philippine crocodile . surveys in 1980 - 1982 revealed a total wild population of approximately 500 - 1 , 000 individuals , but current wild populations may be approximately 100 nonhatchlings . captive breeding efforts are being led by the crocodile farming institute , an entity of the philippine government ( ross 1998 ) .
later aerial surveys ( development alternatives 1992 ) indicated that significant reductions in closed - canopy forest cover had occurred since 1988 as a result of recent logging . as seen from the air , the lowlands and hillsides consist of slash - and - burn agriculture up to the edges of natural forest in the highlands . closed - canopy forest caps only the highest areas on the island .
ornamental plant collecting , especially for the orchids ( phalaenopsis amabilis and paphiopedilum argus ) , pitcher plants ( nepenthes spp . ) , palms ( veitchia merrillii ) , and aroids ( amorphophallus spp . and alocasia spp . ) threatens some plant populations ( davis et al . 1995 ) .
a valuable resin , known as manila copal , is collected from agathis dammara trees . this collection weakens the trees , and slackening production and disease combined with overexploitation are threatening the species ( davis et al . 1995 ; quinnell and balmford 1988 ) .

young birds resemble females but have even less - developed eyespots and usually lack them entirely except on the rectrices . the
