camarhynchus is a genus of bird in the family thraupidae ; all species of camarhynchus are endemic to the galápagos islands , and together with related genera they are collectively known as darwin 's finches .

sometimes classified in the bunting and american sparrow family emberizidae , more recent studies have shown it to belong in the tanager family .

it contains the following species : small tree finch ( camarhynchus parvulus ) medium tree finch ( camarhynchus pauper ) large tree finch ( camarhynchus psittacula ) woodpecker finch ( camarhynchus pallidus ) mangrove finch ( camarhynchus heliobates ) the vegetarian finch ( platyspiza crassirostris ) is often also included in this genus .

kleindorfer , s . ( 2007 ) nesting success in darwin ' s small tree finch , camarhynchus parvulus : evidence of female preference for older males and more concealed nests . animal behaviour , 74 : 795 - 804 .
birds in hand , the scientist sailed from santa cruz , the most populous of the galápagos islands , on a boat bound for isabela island , 150 miles ( 240 kilometers ) away . there , the last remaining wild population of about 80 mangrove finches ( camarhynchus heliobates ) hangs on in two patches of forest no bigger than 12 manhattan blocks .
the mangrove finch , seen here on isabela island , is thought to number around 80 animals in the wild .
one of the world ' s rarest birds , the mangrove finch has dwindled to a habitat the size of just 12 city blocks . here ' s how scientists are trying to bring it back from near - extinction .
francesca cunninghame prepared for a sea voyage on a recent afternoon with some strange cargo : eight fledglings of the mangrove finch , one of the rarest birds on earth .
the brownish , 6 - inch ( 14 - centimeter ) bird is one of the famed
darwin ' s finches ,
several species that were collected and brought back to england by the naturalist after his visit to the galápagos islands in 1835 . ( related :
dna reveals how darwin ' s finches evolved .
)
the galápagos islands finches display a wide variety of beak shapes and sizes . the beaks of this isolated group of birds have evolved to match their niche diets and were an important clue for charles darwin in developing his theory of evolution .
their long , pointed beak curves downward , which helps them lift off tree bark scales and find hidden insects .
this bird has a large , wide bill , earning it the nickname “megamouth . ” its bill is ideal for crushing thick , hard , and large seeds .
stout and strongly curved , this beak’s primary function is to manipulate soft foods , like tree buds , leaves , flowers , and fruit .
this bird has a long , spike - shaped bill that tapers to a point . with this bill , it can probe cactus flowers and fruit for nectar , pollen , and seeds .
with a thin bill perfect for reaching small spaces , this bird eats small insects hidden in bark , mosses , and leaves .
like many other species native to the famous ecuadorian islands , the mangrove finch was devastated by the arrival of alien predators such as rats and cats beginning in the 1600s . it was a much smaller immigrant , though , that brought the mangrove finch to its now precarious status—a type of invasive fly that parasitizes and kills newborn birds .
to rescue the bird that helped shape the theory of evolution as we know it , the charles darwin foundation , which works to preserve the diversity of the galápagos , launched an effort to save the finch nearly a decade ago .
with the bird still in decline , in 2014 the project enlisted the help of the san diego zoo to begin a new phase of the program called
head - starting
: taking mangrove finch eggs from the wild to raise in the safety of an incubator at the charles darwin research station on santa cruz .
see a video of baby finches hatched at the charles darwin research station in 2014 .
since last year , scientists have released 23 hand - raised birds into the wild , including the eight released during cunninghame ' s most recent trip to isabela .
we take the birds at night , so that they ' ll sleep on the journey ,
said cunninghame , who leads the mangrove finch rescue effort .
the first two seasons of the head - starting program have shown encouraging results . but even so , the scientists know it isn ' t the long - term answer to saving the mangrove finch .
this is sort of a stopgap to hopefully prevent extinction until we can figure out how to eradicate the fly ,
said nicole lagreco , an animal - care manager at the san diego zoo who traveled to the galápagos to help collect mangrove finch eggs and raise the fledglings . ( test your darwin knowledge with our national geographic quiz . )
it ' s certainly not the answer to keep them alive forever .
the birds darwin collected in the galápagos inspired him and later scientists to develop the evolutionary principle of natural selection—the idea that animals evolve particular traits to suit their lifestyles . ( read
darwin ' s first clues
in national geographic magazine . )
for instance , as an insect eater , the mangrove finch ' s beak is thinner than the wide , conical beaks of other finches that eat seeds or nuts .
in the late 20th century , mangrove finches once occupied the mangrove forests for which they ' re named along the coasts of isabela and fernandina , the two westernmost islands of the galápagos .
sometime in the 1960s , a type of fly known by its genus name philornis arrived in the galápagos . nobody is sure how it got there ; because the adult fly feeds on fruit , it may have stowed away on a boatload of bananas .
philornis lays its eggs in bird ' s nests ; the fly ' s larvae hatch and feed on hatchlings ' blood and tissue . philornis has hurt many galápagos bird species , but the mangrove finch—already suffering from predation—was especially devastated . ( see
new report highlights dire situation of many u . s . birds .
)
in the first stages of the mangrove finch program , scientists trapped many of the invasive rats and cats , eliminating most of their threat to mangrove finches .
but , under continued assault from philornis , the species disappeared from fernandina and most of isabela , dwindling by 2013 to only 60 or so individuals . ( also see
blue - footed booby threatened in the galápagos .
)
the philornis downsi fly lays its eggs in mangrove finch nests . at night the rice - size larvae attack hatchlings through their ear and nasal cavities . the larvae then feast on the chick’s blood and flesh , causing the bird’s deformation and usually death .
we were seeing up to 95 percent of the nestlings dying in the first month of the breeding season ,
cunninghame said .
but every time the nest failed , the pair would re - nest . some pairs would nest up to five times in one season , to rear at best maybe one or two chicks .
and from that we got the idea that we had quite a constant supply of eggs , but they weren ' t getting a chance .
that led to the decision to take the eggs and raise the hatchlings in captivity , where they ' d be protected from the flies .
after the babies hatch , workers use forceps to hand - feed them a high - protein diet that includes scrambled egg , papaya , wasp larvae , and moth guts .
young birds are then transported back to isabela , placed in a large aviary , and provided with natural food . a month later , the doors to the aviary are opened and the youngsters join their relatives in the wild .
a person feeds a baby mangrove finch , which is being hand - raised for eventual release into its native habitat .
scientists are hard at work on possible control programs for philornis , including trapping mass numbers of male flies , sterilizing them , and releasing them back into the wild to mate ( unsuccessfully , of course ) with females .
killing the flies outright would be risky , since
we have to make sure that whatever method is used is safe and won ' t have short - term or long - term effects on the birds ,
notes charlotte causton , senior researcher at the charles darwin foundation .
another measure would involve infusing cotton balls with bird - safe insecticide and placing them in mangrove finch habitat , hoping that the birds would pick up the cotton and use it to build their nests . ( see
saving a darwin ' s finch from extinction .
)
definitely one of the project ' s long - term goals is to reestablish them in some of those mangroves where they historically were , on both isabela and fernandina .
despite the damage done by introduced predators and parasites , the rather surprising fact is that no bird species is known to have gone extinct in the galápagos since people arrived more than four centuries ago .
raising mangrove finch fledglings is expensive and labor - intensive , but , for now , it ' s the only way that cunninghame and her team know to keep that record intact .
the diminutive size and distinctive short , curved beak of the small - tree finch help to distinguish it from the other twelve species of finch that are endemic to the galapagos ( 2 ) ( 3 ) . collectively known as darwin’s finches , these remarkable birds have received a high degree of scientific attention , as the diversity of beak size and shape between the species provides strong evidence for charles darwin’s theory of evolution by natural selection ( 2 ) . the male small tree finch can be readily distinguished from the female by the black colouration of the head , shoulders and chest , which develops over the course of five annual moults . otherwise , both sexes possess uniform , dull greyish - brown plumage ( 4 ) .
an insect - feeding specialist , the small tree - finch’s curved , grasping bill enables it to deftly pick adult insects and caterpillars from the surface of bark and leaves , and to bite through the bark of twigs and leaf stems to expose insect larvae . despite its specialisation , this species also consumes fruit , seeds and nectar , particularly during the dry season when these foods may form the major part of its diet ( 3 ) .
darwin’s finches usually breed during the hot and wet season when food is most abundant . monogamous , lifelong breeding pairs are common , although mate changes and breeding with more than one partner have also been observed ( 2 ) . in order to attract a female , male small tree - finches build dome - shaped nests from which they make courtship song displays . upon arrival at the display nest , the female either accepts both the nest and the male ; accepts the male but not the nest ( in which case the pair constructs a new nest ) ; or rejects both . interestingly , older males are more frequently selected as mates due to the fact that as they age , male small tree - finches become more adept at concealing their display nest amongst vegetation . these nesting sites therefore suffer less predation and are more likely to result in breeding success ( 4 ) . generally a clutch of three eggs is laid , which are incubated by the female for about twelve days , and the young brooded for a further two weeks before leaving the nest ( 2 ) . nestlings and juvenile darwin’s finches are frequently preyed upon by the short - eared owl ( asio flammeus ) , while adults are occasionally taken by galapagos hawks ( buteo galapagoensis ) and lava herons ( butorides sundevalli ) ( 2 ) .
the small tree - finch can be found on several islands in the galapagos archipelago , namely : isabela ; fernandina ; santiago ; pinzón ; santa cruz ; santa fé ; san cristóbal ; and floreana . this species was also previously found on rábida island , but is now believed to be extinct ( 5 ) .
the small tree - finch principally inhabits humid , evergreen forest located between elevations of 300 and 700 metres , but may also be found in arid lowland areas , dominated by deciduous trees , shrubs and cacti ( 3 ) .
classified as least concern ( lc ) on the iucn red list ( 1 ) .
increasing levels of human activity on the galapagos are creating significant threats to the islands’ native wildlife . darwin’s finches , in particular , are vulnerable to habitat destruction , invasion by non - native competitors and predators , and the introduction of diseases such as avian pox ( 6 ) . despite these threats , the small tree - finch is not currently considered to be threatened , as its population is large and not undergoing a major decline ( 7 ) .
the majority of the galapagos archipelago forms part of the galapagos national park , a world heritage site . a management plan is in place for the islands , and the ecuadorian government and non - governmental organisations are working to conserve the unique biodiversity of the galapagos ( 8 ) . more specifically , scientists at the charles darwin research station are working to improve our understanding of darwin ' s finches to ensure their conservation . this includes monitoring of populations and investigating introduced diseases ( 6 ) .

the medium tree - finch is one of darwin’s finches , a group of 13 birds endemic to the galapagos islands that helped charles darwin formulate his theory of evolution . the medium tree - finch is mostly greyish - brown , with whitish or yellowish underparts . the sexes differ in the colour of their head ; the female’s is greyish - brown whilst the male’s is blacker ( 2 ) . all of darwin’s finches evolved from a single species , but now each possess a specialized bill , adapted to their habitat and diet . the three tree - finch species all have a sharp , grasping bill , and it is believed that the medium tree - finch may be a hybrid of the large and small tree - finches ( 3 ) .
with its specialized bill , the medium tree - finch feeds on insects , nectar , young buds and leaves , by probing crevices in tree bark and searching under twigs and foliage ( 2 ) .
endemic to floreana in the galapagos islands , ecuador ( 2 ) ( 4 ) .
occurs in montane evergreen and tropical deciduous forest and in humid scrub , generally over elevations of 100 meters ( 2 ) .
classified as critically endangered ( cr ) on the iucn red list ( 1 ) .
the medium tree - finch used to be found on the coast , but is now restricted to the highlands ( 4 ) , as a result of the extensive habitat destruction and degradation on floreana , caused by agriculture and free - ranging livestock . introduced predators such as cats , dogs and rats also pose a threat ( 2 ) . the introduction of diseases , such as avian pox , may also potentially threaten finches . a population of the large ground finch has already become extinct on floreana , which illustrates the vulnerability of finch species to such threats .
the majority of the galapagos archipelago forms part of the galapagos national park , a world heritage site . a management plan is in place for the islands , and the ecuadorian government and non - governmental organisations are working to conserve the unique biodiversity of the galapagos ( 5 ) , all of which will help ensure the future of this species . more specifically , scientists at the charles darwin research station are working to improve our understanding of darwin’s finches to ensure their conservation . this includes monitoring of populations and investigating introduced diseases ( 3 ) . however , in 2009 the iucn upgraded the medium tree - finch from vulnerable to critically endangered in light of its tiny range on a small island , and indications of a rapid decline in the species due to the effects of a parasite , philornis downsi ( 2 ) .

the large tree - finch is one of thirteen finch species endemic to the galapagos islands , collectively known as darwin’s finches , which each possess markedly different bill shapes and sizes ( 3 ) . such differences helped charles darwin to formulate his theory of evolution , and provide some of the most convincing evidence for “evolution in action” ( 2 ) . this species possesses a large , powerful bill , with a thick base and a markedly down - curved culmen ( 3 ) ( 4 ) . the male can be readily distinguished from the female by the black colouration of the head , shoulders and chest , which develops over the course of several annual moults ( 3 ) ( 5 ) . otherwise , both sexes possess uniform , dull olive - green plumage ( 3 ) .
the remarkable diversity of beak forms amongst darwin’s finches allows each species to feed in a specialised way ( 7 ) . with its curved , powerful beak , the large - tree finch is capable of biting through the bark of twigs , exposing adult insects and larvae such as caterpillars , which are then consumed ( 4 ) . while invertebrates form the major part of its diet , this species will also consume fruit , especially during the dry season ( 4 ) .
darwin’s finches usually breed during the hot and wet season when food is most abundant . monogamous , lifelong breeding pairs are common , although mate changes and breeding with more than one partner have also been observed . breeding pairs maintain small territories , in which they construct a small dome - shaped nest with an entrance hole in the side . generally a clutch of three eggs is laid , which are incubated by the female for about twelve days , and the young brooded for a further two weeks before leaving the nest . the short - eared owl ( asio flammeus ) , frequently preys on the nestlings and juvenile darwin’s finches , while adults are occasionally taken by galapagos hawks ( buteo galapagoensis ) and lava herons ( butorides sundevalli ) ( 2 ) .
the large tree - finch can be found on several islands in the galapagos archipelago , namely : isabela ; santa cruz ; santa fé ; fernandina ; santiago ; floreana ; marchena ; and pinta . this species was also previously found on the islands of pinzón and rábida , but is now believed to be extinct ( 3 ) .
the large tree - finch principally inhabits humid , evergreen forest located between elevations of 300 and 700 metres , but may also be found in arid lowland areas , dominated by deciduous trees , shrubs and cacti ( 4 ) ( 6 ) .
like other bird species endemic to the galapagos , the large tree - finch is affected by ongoing habitat destruction , invasive species , and introduced diseases , such as avian pox ( 7 ) . nevertheless , despite being uncommon in some parts of its range , the global population of this species is not considered to be small enough , nor undergoing a sufficiently significant decline , to warrant a threatened classification ( 6 ) .

the remarkable feeding behaviour demonstrated by the woodpecker finch involves the use of twigs and cactus spines to push , stab or lever insects and spiders from tree - holes and crevices ( 3 ) . displaying extraordinary behavioural adaptability , this species will not only seek out a variety of different feeding implements , but will also manipulate them to make them more manageable , for example by shortening cactus spines with its bill ( 7 ) . although the woodpecker finch ' s use of tools enables it to access inaccessible sources of food , particularly those with the high energy content such as spider egg sacs , it incurs a significant cost by being a relatively time consuming foraging technique . therefore , it is a behaviour most commonly exhibited by woodpecker finches in the arid zone during the dry season , when easily accessible food supplies are scarce . in contrast , during the arid zone wet season , and throughout the year in the
zone , invertebrate prey are generally abundant and easily accessible , hence the woodpecker finch is more reliant on its specialised , pointed bill to probe amongst moss and bark for prey , and rarely uses tools ( 3 ) . darwin ' s finches usually breed during the hot , wet season when food is most abundant . monogamous , lifelong breeding pairs are common , although mate changes and breeding with more than one partner have also been observed . breeding pairs maintain small territories , in which they construct a small dome - shaped nest with an entrance hole in the side . generally a clutch of three eggs is laid , which are incubated by the female for about twelve days , and the young brooded for a further two weeks before leaving the nest . the short - eared owl (

one final interesting tidbit - there are some very interesting mimetic relationships that exist between several tobies and three filefish species . all of these are examples of batesian mimic - where a toxic species is mimicked by a non - toxic form . the saddled toby ( canthigaster valentini ) is mimicked by the saddled filefish ( paraluteres prionurus ) , the pearl toby is mimicked by the red sea puffer mimic ( paraluteres arquat ) while an undescribed monacanthid , known commonly as the spotted puffer mimic ( paraluteres sp . ) , resembles the ocellated toby .
dorsal spines ( total ) : 0 ; dorsal soft rays ( total ) : 9 - 10 ; anal spines : 0 ; anal soft rays : 9 . differs from other atlantic canthigaster species by the long anterior extension of the lower horizontal dark stripe on the flank ( composed of irregular horizontal and diagonal bars and originating as a solid stripe on the ventral caudal fin margin ) . this stripe reaches the pectoral fin base . differs from c . jamestyleri by the presence of a dark caudal - fin margin , the absence of vertically oriented bars on the caudal fin , the possession of fewer stripes and spots on body especially on the dorsum , as well as by the absence of a small black irregular spot on the anal fin base ( ref . 43205 ) .

both the papuan and ocellated tobies are excellent aquarium inhabitants . the only possible drawback with these tobies is that some individuals will nip the fins of other fishes .
) , the frogfishes ( antennariidae ) , the porcupinefishes ( diodontidae ) and the pufferfishes ( tetraodontidae ) . apparently , by increasing their size these animals reduce the chances that a predator will be able to ingest them , or by suddenly inflating they might startle a would - be predator , or make themselves difficult to extract from a reef crevice .
the two species differ in coloration . the papuan toby is brown overall with blue spots on the side of the body , blue lines on the back and the dorsal surface of the caudal peduncle , a black spot at the base of the dorsal fin and orange on the underside of the snout . the ocellated toby has spots on the side of the body , on the back and caudal peduncle , with some lines radiating from the eyes , and has no or little orange on the ventral surface of the snout , head or belly . both species typically have orange on the tail , but c . papuensis usually sports more orange . the papuan toby is probably sexually dichromatic and dimorphic . in the closely related c . solandri the males attain a larger size and typically have fewer , larger spots than females . there also appears to be some size and color differences between the sexes in the papuan toby .
toby fighting usually begins with bouts of displaying , where the combatants increase their apparent size by erecting a ridge on the back and belly . they perform these lateral displays to try and drive their opponent away with out actually coming to blows . but , if one individual does not back down and leave the area biting will usually ensue . this can result in severe injuries . the problem with captive combat , is that the fish that retreats cannot “leave the area” since our aquariums are so much smaller than the normal toby territory and hence this subordinate is chastised by the more dominant , or territory holding fish . if it gets to the point where biting occurs you will need to separate the fish or risk losing one of them to injury . you could try taking the dominant fish out of the tank and placing it in a different aquarium for a week or two , and then try adding the more aggressive fish back into the tank and see what happens . in some cases the subordinate will accept its position in the pecking order from the onset and avoid the more dominant fish . in these cases lethal fighting usually does not occur .
if a specimen shows chronic , abnormal distention of the abdomen it may be suffering from an internal infestation of nematode worms of the genus philometra . unlike normal toby inflation , the distended abdomen of fish suffering from this infection will be asymmetrical in form and will change shape as the parasites move around . schleser ( 1994 ) recommends introducing fenbendazole ( add at a volume of 1 % of the active ingredient ) to gelatin based foods to eradicate intestinal worms .
a smaller c . solandri beginning to preform an aggressive display . note the partially erected ridge on the ventrum .
although it can break the ice at parties , provoking your toby to inflate is not a good puffer maintenance practice . this will stress your fish and it could prove to be fatal if your toby ingests air . tobies sometimes have difficulty expelling air from the stomach and end up bobbing helplessly at the water ' s surface . another word of warning ; these fish are not strong swimmers , so make sure all siphons tubes have strainers or small specimens may end up in your power filter .
