i have seen lots of this fish almost under every rock along turkey ' s mediterrenean coast . they are so friendly and curious : )
i had wanted to try quinn ' s for sometime . my grandfathers were both north sea fishermen and i love great fish and chips . when in london i like to go to the north sea fish restaurant near st . pancras which is wonderful but when i am . . .
my daughter suggested we try quinn ' s the next time we were in comber . we arrived around 6 . 00 and while the carry out was very busy there were many tables available in the sit - in section . the staff were friendly and attentive . we order two fish and . . .
the painted comber spends much of its time in rocky caves . it is usually solitary or in small groups . it comes out of hiding around dusk to feed on various crustaceans , fishes , and worms . indeed , this fish tends to give away a well hidden octopus nest , since it lies in waiting outside the octopus nest to feed on the left - over bits of shellfish .
the photo of this painted comber was taken at a depth of 30m outside of the blue hole , a natural feature at dwejra , not far from the famous azure window , on gozo ’s west coast .

my wife and i always go here for chips in comber . we make it in at least once a fortnight . great fish , great chicken goujons and brilliant chips ! big portions , too . the beef and bird burger was a force to be reckoned with when i got it . staff are friendly and everything is cooked in front of you - can ; t get fresher than that . see you tomorrow night . . .
also known as rockcods , cods , hinds , trouts , pointed comber , redfish and lettered perch . found in murky waters of lagoons and seaward reefs , on rocky bottoms and in seagrass beds . colour varies . they feed on small fish and invertebrates . length - 30cm depth - 5 - 150m widespread eastern atlantic , mediterranean & black sea . sea bass are solitary carnivores that hunt near the bottom usually at dusk . food is drawn into their mouths by a powerful suction when they open their overly large mouths and then swallowed whole . spawning is seasonal and controlled by the moons phase .
hi ken , many thanks for your review and i ' m glad you enjoyed your fish . i was however disappointed that you found the chips to be poor . i can assure you that we do cook all our food fresh and that the chips you had were . . .
very pleasant couple serving excellent fare . fish and mushrooms battered before my eyes , then cooked before being nicely presented on white square plates , with the nice touch of fake newspaper on top . this was actually greaseproof , and had
headlines
about the café . sadly , deserted at . . .
is widely distributed in the eastern atlantic and is known from the straits of gibraltar to angola , madeira and canary and cape verde isalnds , sao tome and prncipe . it also inhabits the mediterranean and black seas , eastern atlantic to british isles , azores , and the red sea . this fish is common and abundant .
got a carry out of fish , pastie & chips along with a portion of gravy . the produce was good quality but very greasy , so much so we didn ' t finish what we got and the gravy was really lumpy . if they could sort the grease problem out i think it would be very good . disappointed .

stephensia brunnichella is a moth of the elachistidae family .

it is widespread throughout europe .

in the north , the distribution extends up to southern sweden and finland and in the east it ranges as far as asia minor and the crimea .

the wingspan is 8 – 9 mm .

the larvae feed on calamintha nepeta , clinopodium vulgare and satureja calamintha .

they mine the leaves of their host plant .

the mine starts as a long , narrow , full depth gallery running toward the leaf tip .

the frass is found in a narrow central line .

after reaching the leaf tip , the mine becomes a large , full depth , brown blotch .

here , the frass is deposited in black lumps .

the larvae may vacate the mine and start elsewhere .

pupation takes place outside of the mine , in a white spinning , mostly between the leaves of the host plant .

the larvae have a greenish body with a black head .

they can be found from autumn to april and again in july .

the taxonomic relationship of this petrel for decades remained unclear with many authors considering it to be a dark form of the black - capped petrel . recent evaluations however have shown the jamaica petrel to be a distinct smaller species more closely related to the cape verde petrel . this is further supported by the bird’s feather lice which show considerable differences with those of black - capped petrels . dna analysis is warranted but there is little question that this is a distinct species .

“finding this colony of petrels on dominica is a real game - changer for black - capped petrel conservation , ” said scientist adam brown , the leader of the expedition that discovered the birds .
black - capped petrel is a distinctive gadfly petrel with a clearly defined black cap separated from the dark mantle by a white collar and with conspicuous white uppertail coverts that form a broad u shape . discrete variation among individuals , mostly in the extent of dark
cap ,
suggests that black - capped petrel might be a complex of multiple species with different nesting seasons ; more research is needed to determine the taxonomic status of these different types . although black - capped petrel can be seen readily off the coast of the southeastern united states , particularly in gulf stream waters from north carolina to florida , the global population is in fact quite small and faces threats both at the caribbean nesting colonies and at sea .
radar surveys conducted in dominica in january 2015 strongly suggest that black - capped petrels persist there ; hundreds of petrel - like targets were recorded over 17 separate coastal and inland flight corridors , and eight individual black - capped petrels were observed over 5 locations ( brown 2015 ) . these data , when coupled with recent observations of downed black - capped petrels on the island , suggests that there are still petrels breeding on the island , although the last confirmed nesting date was 1862 .

it is a truly fascinating time to study the black - capped petrel . this working group is currently using multiple methods to learn more about the nesting sites and nesting behavior of this species . this information will be used to guide conservation plans and help ensure the survival of this remarkable seabird .
birds disperse over the caribbean and atlantic from the north - east usa to north - east brazil , but the at - sea range has contracted in the north and west . occasionally birds are entrained in hurricanes and deposited far inland - for example , hurricane fran displaced what was probably many tens of black - capped petrels into the great lakes in the northeastern us . generally , in temperate summer months of june - september , black - capped petrel frequents the western edge of the gulf stream .

i’m working with a species called the black - capped petrel . it’s a very difficult species to study because of a couple of unique things about it . it’s a seabird so it spends all of its day on the ocean feeding , but at night it comes into the centre of the island to nest .
nests are typically found along forested mountain slopes and cliffs at elevations from 1 , 500 metres up to 2 , 300 metres . during the non - breeding season , from approximately may to november , the black - capped petrel lives and forages permanently at sea with the largest numbers concentrated around areas of nutrient rich upwelling

to distinguish a jamaica petrel from the trinidade petrel , the dark morph trinidade would have white on the leading edge of the underwing , white in the tips of the primary and secondary underwing coverts , and white in the bases of the underside of the primaries and secondaries . the jamaica petrel lacked this white underwing feathering . similarly , a dark - morph kermadec petrel has white in the underside of the primaries , on the face adjacent to the bill , around the eyes , and on the leading edge of the underwing . the only light coloration on the jamaica petrel was the silvery rump .
finding this colony of petrels on dominica is a real game - changer for black - capped petrel conservation ,
says biologist adam brown from environmental protection in the caribbean , which carried out the survey . dominica ' s forests are well - protected , giving conservationists a

black - capped petrels previously nested on guadeloupe and martinique , but have not been documented there since before 1900 . however , hope persists for rediscovery on guadeloupe ( a . chabrolle in litt . ) based on offshore observations and the presence of inaccessible island peaks . likewise , hope persists for cuba . though there is no documentation of black - capped petrels nesting in cuba in the past or currently , there have been observations of birds flying inland at dusk from a known foraging area .

nesting birds commute long distances from breeding to foraging sites , typically feeding in flocks . it is primarily nocturnal and crepuscular , feeding on squid , fish , crustaceans , and sargassum . in its primary foraging range , the black - capped petrel is most influenced by the position of the gulf stream , a dynamic current system , and not sea surface temperature or depth . ( simons et al . 2013 ) .
the jamaica petrel pelagic expedition . a pelagic expedition off jamaica , and off the islands of guadeloupe and dominica , november - december 2009 .
black - capped petrels are highly pelagic and undertake long - distance foraging trips . a compendium of about 5 , 000 at - sea observations indicates that waters in or adjacent to the florida current and the gulf stream between north florida and southern virginia provide a distinct and relatively confined foraging range of black - capped petrels , with concentrations observed there throughout the year . in the caribbean sea , black - capped petrels can occur within the inter - island regions , straits and offshore zones of both the greater and lesser antilles but still primarily east of 80°w . the first satellite tracking of this species ( three individuals ) suggest a similar but more spatially expansive range , including regular occurrence in the caribbean sea between hispaniola and south america and regular occurrence east of primary foraging area indicated by the at - sea observations ( jodice et al . 2015 ) .

the black - capped petrel forages predominantly in multispecies flocks throughout the night but with peak activity at dawn and dusk ( 2 ) ( 3 ) ( 13 ) . while some time is spent foraging on the ocean surface , the preferred technique is to snatch items with their bills whilst in flight ( 3 ) ( 13 ) . fish , squid and invertebrates all form part of the petrel’s diet , with fauna associated with sargassum seaweed reefs being particularly popular . in addition , these birds are not averse to occasionally scavenge behind fishing vessels ( 2 ) ( 3 ) ( 13 ) .
the black - capped petrel ( pterodroma hasitata ) , also known as the diablotin , is one of the caribbean’s most fascinating seabirds , and one of its most threatened . spending most of its life at sea , this species comes to land only to breed , nesting in burrows or crevices which they visit only in cover of darkness . almost wiped out by overhunting , the species only persists in remote mountain areas of a few caribbean nations .

in january 2015 , epic teamed up with scientists from dominica’s ministry of agriculture and fisheries to conduct a systematic survey of the island aimed at determining the petrel’s status .
the endangered black - capped petrel was last confirmed as nesting on the island in 1862 . but a survey that started in january recorded 968 of the birds over the mountains , where they could potentially be making nests , the birds caribbean organisation says . until now , the only known colonies were on the island of hispaniola - now divided between haiti and the dominican republic . only 1 , 000 to 2 , 000 breeding pairs are estimated to live there , and their habitat is under threat .
a relatively large , distinctive , long - winged pterodroma (
gadfly
) petrel . the clearly defined black cap , separated from the dark mantle by a weak white collar , and the conspicuous white ' rump ' ( uppertail coverts ) forming a broad ' u ' shape , are unmistakable , even from substantial distances .
consequently , brown’s team of researchers adopted a technique developed to study petrels on hispaniola : they employed a portable marine - radar array and nightvision scopes to locate and identify birds as they flew to and from potential nest areas in the island’s highest peaks . and the biologists were successful , counting no fewer than 968 black - capped petrels .
the presumed breeding season of the black - capped petrel was already underway when the grupo jaragua team ( of ernst rupp , jairo issa arache , gerson feliz , and josé luis castillo ) started the expedition to search for nests on 3 rd march . the team was joined by two members ( djeff alexis and evanita sanon ) of ojaa – a youth organization in anse - à - pitres , haiti – who have been involved with grupo jaragua - led conservation efforts for the critically endangered ricord’s iguana cyclura ricordi .

it is primarily nocturnal and crepuscular , feeding on fish , invertebrate swarms , fauna associated with sargassum seaweed reefs , and squid . it is attracted to localised upwellings , where the mixing of surface and deep oceanic waters produces nutrient - rich areas . the black - capped petrel forages predominantly in multispecies flocks throughout the night but with peak activity at dawn and dusk . while some time is spent foraging on the ocean surface , the preferred technique is to snatch items with their bills whilst in flight . fish , squid and invertebrates all form part of the petrel ' s diet , with fauna associated with sargassum seaweed reefs being particularly popular . in addition , these birds are not averse to occasionally scavenge behind fishing vessels
for pelagic birders on the east coast , it doesn’t get much better than a black - capped petrel in a breeze . like all pterodroma s , they cruise on the wind like a fine italian sportscar on a mountain road , effortlessly and with breathtaking abandon . for decades the only known nest sites of this charismatic seabird were in patches of high mountain forest on the island of hispaniola – including some of the last remaining patches of native forest in haiti – where rampant destruction of natural resources continue to make their long - term survival uncertain .
due to their prevalence off the coast of the u . s . some researchers believe that there are other breeding colonies not yet accounted for . expeditions to find breeding birds in cuba have been made , but no colonies have been found thus far . likewise , reports of black - capped petrels in dominica have not been followed by the discovery of other nesting sites .
adam brown , co - founder and lead scientist at epic states , “finding this colony of petrels on dominica is a real game - changer for black - capped petrel conservation . for years we thought the only remaining colonies of petrels were on hispaniola , where nesting habitat is diminishing at an alarming rate and pressures of human activity are significant . dominica is an island - nation where nature conservation is a high priority and forests needed by petrels are well protected , so we now have a huge new opportunity to undertake conservation efforts to preserve this imperiled species . ”

black - capped petrels presumably bred historically in the sierra maestra mountain range of southeastern cuba ( nicasio viña , personal communication ) . this area shares its name with a nearby town , as well as an adjacent point of land also named la bruja where the petrels are known to feed at night . locals in the area reported hearing strange nocturnal sounds in 1976 which n . viña assured residents were birds , not demons or witches ( garrido 1985 ) . cuban ornithologists affiliated with the havana national museum of natural history collected six specimens of black - capped petrels as the petrels were coming ashore at dusk . although this potential breeding colony was never found , as the cliffs within the sierra maestra range are largely inaccessible , there is additional recent evidence to suggest that a stronger survey effort in this area is warranted .
howell and patteson ( 2008 ) suggest that variation in black - capped petrels may reflect multiple cryptic species , as evidenced by different plumage characters and different molt sequence and timing . their discussion is the most extensive and comprehensive treatment to date for this species , but even they suggest that additional information is needed to understand whether this variation is a functional of subpopulations , geographic variation , multiple cryptic species , molt timing , or some combination of these .
this species may seem variable in appearance , but at least one recent treatment of the species suggests that such variation may be more discrete than previously thought ( howell and patteson 2008 ) .
black - faced
and
white - faced
individuals form discrete plumage and morphological clusters :
black - faced
birds tend to show dark or black cheeks and auricular areas , with larger and more obvious dark collar , more extensive dark cap , and darker plumage on the nape ;
white - faced
birds are primarily opposite of these patterns , in showing substantially reduced dark coloration in these areas . note , however , that this variation is not particularly well understood , nor is it completely discrete - intermediate plumages exist .
the only known extant black - capped petrel breeding populations are located in the highlands of hispaniola , predominantly in southern haiti but also in low numbers across the border in the dominican republic ( 7 ) ( 8 ) ( 9 ) ( 10 ) . historically , breeding populations were also recorded on several other caribbean islands , including martinique , guadeloupe , dominica and cuba ( 4 ) ( 10 ) ( 11 ) . it is almost certainly extinct on martinique and guadeloupe ( 4 ) but recent reports suggest the presence of breeding birds on cuba ( 12 ) . its foraging range extends throughout the caribbean and the atlantic , but is observed most frequently on the western edge of the gulf stream from northeast south america to northeast usa ( 2 ) ( 3 ) .
is actually a cryptic complex of several species . only cape verde storm - petrel ( o . jabejabe ) and monteiro ' s storm - petrel ( o . monteiroi ) have been recognized thus far , but ultimately at least one other atlantic taxon is likely to be split from band - rumped . the form , band - rumped storm - petrel ( grant ' s ) is yet undescribed , but increasingly well - known in its east atlantic breeding areas and its vocal differences have been described by the sound approach team . in addition , at least two and maybe more pacific taxa ( including the galapagos form , also available in ebird ) surely will be split . debate continues about which form ( s ) occur ( s ) in united states waters . while this has no effect on current lists ( since only nominate and the undescribed taxa are yet documented or believed to visit north american waters ) , it is worth keeping in mind that the ebird / clements definition of band - rumped storm - petrel is different from that of the aou .
not only is this a fantastic conservation story , but there’s an interesting taxonomic angle as well . birders in the gulf stream have long noted that black - capped petrels come in two varieties , “light - faced” and “dark - faced” . these two forms not only look different , but they have different molt timing and , as a study using museum specimens published in 2013 found , significant genetic distance as well . known breeding populations on hispaniola consist of dark - faced birds so the breeding grounds of the light individuals was long suspected to be dominica .
to be honest , i’m a biologist , i’m not a humanitarian so this not my area of expertise . but i know these things need to be done for the petrel to survive on haiti . there’s a delicate balance between the poverty of the people and the success of the bird .
this is not unique in the world ; if it’s not the petrel , than it’s the elephant or the bengal tiger . it’s that poor , rural communities live next to areas where there are endangered species . i know programmes like this have had success , so i know this one can too .
“this is a nocturnal seabird with a deadly attraction to oily surfaces , so an oil spill in the petrel’s habitat could drive it to extinction , ” said jacki lopez , florida director at the center . “this cliff - dwelling bird urgently needs protection from imminent plans to open its fishing grounds to oil drilling . ”
field investigations on hispaniola suggest that black - capped petrels are laying eggs in mid - to late january , chicks are hatching in mid - to late march and fledglings are departing the colony sites in mid - june to early july ( simons et al . 2013 ) . all nests located to date are at high elevations ( > 1500 m ) and while most are in inaccessible areas ( steep slopes , heavily forested ) some are not ( e . rupp , in litt . ) nesting success from monitoring over 4 years was 70 - 77 % ( n = 47 nests ) with abandonment and predation causing most failures ( e . rupp , in litt . )
i feel optimists about it . being in dominica , where i am right now , where the conservation challenges are different helps with that . if the petrels are here on dominica – where the forests are really protected and the people care a lot about keeping the island the same – then i feel really good about the future of the petrel .
there are only 13 known breeding colonies in haiti and the dominican republic and fewer than 2 , 000 breeding pairs . the petrel is considered endangered by the international union for conservation of nature , the international authority on endangered species ; it is threatened by the destruction of its breeding habitat through deforestation , as well as contamination and oil and gas development .
president obama recently opened the atlantic coast to seismic exploration activities for oil and gas , and the department of the interior is reviewing 10 applications for permits . additionally , the administration proposed a plan to offer an area off the mid - atlantic for drilling in its five - year plan for offshore oil leases . these industrial activities threaten the petrel and its habitat .
, of south trinidade island has been documented in summer from the outer continental shelf of the southeastern united states and this species is also expected to occur in the west indies region . although the two species are not closely related , its size and dark phased plumage are superficially similar to that of the jamaica petrel . at sea sightings of reported jamaica petrels need to be evaluated with caution .
we have made an effort to include many known hybrids that occur in the wild . while this is not a list of every single hybrid combination reported , we have tried to include those that are frequent enough and distinctive enough that they might be reported by birders . these range from the common combinations like
american black duck x mallard
and
western x glaucous - winged gull
to considerably rarer combinations like
as such , the petrel is highly vulnerable to threats of anthropogenic - related mortality ( including disorientation by artificial lighting and collision with tall structures ) and rampant habitat destruction . as a result of these activities and events , and the potential for increasing activities that expose these petrels to risks , this species is seriously threatened . it ' s conservation status is rated by birdlife international as endangered ; birdlife international estimates that the total population is 5 , 000 individuals , and that the population is in decline .
the black - and - white bird was once a common sight on the island , but was wiped out in the late 1800s by hunting and the introduction of predators . they are notoriously hard to spot , spending only a few months on land each year , and flying to their underground burrows at night . biologists used radar and night - vision scopes to count those discovered in dominica . they now plan to trek into the mountains early next year to look for nests , to confirm that the birds are breeding .
western swamphen ( porphyrio porphyrio ) ; african swamphen ( porphyrio madagascariensis ) ; gray - headed swamphen ( porphyrio poliocephalus ) ; black - backed swamphen ( porphyrio indicus ) ; philippine swamphen ( porphyrio pulverulentus ) ; and australasian swamphen ( porphyrio melanotus ) . the species was recently added to the north american list because of an established , introduced population of gray - headed swamphen in florida . since that time , a vagrant african swamphen has also appeared on bermuda . the nacc considered this split in 2016 but chose not to split purple swamphen at this time .
mass : females range from 347 - 545 grams , with substantial clustering into three different classes of mass that relate to black - , white - , and intermediate - face color patterns ; males of the same mass classes range from 349 - 591 grams . wing chord : females range from 268 - 305 mm ; males range from 279 - 317 mm . exposed culmen : females range from 28 . 8 . 39 . 9 mm ; males range from 30 . 1 - 34 . 7 mm . all data summarized from howell and patteson ( 2008 ) .
unlike many species of seabird that are critically threatened or highly endangered ,
considerably more is known about the petrel ' s marine ecology than its breeding biology
( simons et al . 2006 ) . this species has a small , fragmented and declining breeding range and population and has been extirpated from a number of sites ; declines are likely to continue as a result of habitat loss and degradation , hunting and invasive predators ( e . g . norway rat , indian mongoose ) . these factors remain key threats in haiti . birds are also predated by introduced mammals , and urbanization and increases in artificial lights may disorient birds into colliding with trees , wires and buildings . a telecommunications mast with guy wires erected in 1995 in the dominican republic poses a major , potential collision hazard .

this species is classified as endangered because it has a very small , fragmented and declining breeding range and population . it has already been extirpated from some sites , and declines are likely to continue as a result of habitat loss and degradation , hunting and invasive predators .
pterodroma hasitata is confirmed as breeding in hispaniola ( comprising the nations of haiti and the dominican republic ) . the population there is estimated as no more than 1 000 breeding pairs , perhaps as few as 500 , and a total population of 2 000–4 000 birds . the highest density of nests and most of the population occurs on la visite ridge in the western extent of the massif de la selle , haiti . smaller populations occur eastward along the massif de la selle and across the border in the sierra de bahoruco of the dominican republic , as well as around pic macaya in massif de la hotte in western haiti . radar surveys and aural observations indicate that small populations occur in other areas to the north and east in the dominican republic but nests have yet to be located ( e . rupp , in litt . ) taking into account each of these known and suspected breeding sites , all of which are quite small , an area of occurrence estimate of 20 km 2 is reasonable ( e . rupp , in litt . ) .

the population undoubtedly declined through the 19th and 20th centuries during which time breeding populations on guadeloupe , dominica and martinique may have been entirely extirpated . this decline is thought to have continued during recent years but requires confirmation .
2013 ) . the most significant current threat on haiti is loss of habitat from encroachment of humans for agriculture and forest product collection . habitat loss from fire , and fatal attraction to lights ( flames , cities , communication towers ) are threats for all populations in hispaniola . collection by humans and predation do account for some mortality , but burrow monitoring by camera trap and nest success rates indicate that these are not significant drivers of population decline .

develop and undertake conservation strategies to halt encroachment in haiti and improve park management ( e . g . fire control ) in haiti and the dominican republic . continue surveys to determine distribution on hispaniola , dominica and at - sea and to determine presence on cuba , jamaica and guadeloupe . research key threats in order to reduce and / or mitigate them , and monitor population status throughout range .

“when it comes to protecting endangered species like this seafaring bird , delay can mean death , ” said lopez .
the center for biological diversity is a national , nonprofit conservation organization with more than 825 , 000 members and online activists dedicated to the protection of endangered species and wild places .
at one time , this bird was known in north america only from scattered waifs blown inland by hurricanes . now it is known to occur regularly in the gulf stream , far offshore from the southeastern states . it breeds only in the west indies , and has disappeared from most former nesting areas ; should be considered at risk of extinction .
formerly an abundant nester on several islands , but numbers dropped sharply in middle of 19th century . decline often blamed on introduction of mongoose , but that occurred in 1870s , after decline already apparent . introduced rats more likely responsible , along with humans catching petrels for food . now known to nest in mountains in haiti , dominican republic , and cuba , and vulnerable in these few spots .
open ocean . forages over warm deep water far off southeastern coast of north america , especially over western edge of gulf stream . also over seamounts or submarine ridges where turbulence may bring food nearer surface . nests around steep forested cliffs in west indies ; may have nested in burrows on more level ground before exotic predators were introduced there .
often in loose small flocks , associated with other seabirds . forages by dipping to surface of water , with feet down and pattering on water , or by settling briefly on water with wings upstretched ; sometimes feeds while swimming . may do most feeding early morning and late evening , when some prey items are closer to surface .
