Biology ( Inglês )

fornecido por Arkive
The scientific name of the Negros bleeding-heart hints at the behaviour of this bird. Galli means chicken and columba means pigeon, and this pigeon spends much of its time on the ground searching for food, like a chicken (6), only flying up into trees to roost, take cover or breed (7). Unfortunately, very little information exists regarding the diet and breeding behaviour of this bird, possibly due to its rarity. However, clutches of two eggs were found on the island of Panay in March (8), and the development of two chicks on Panay was closely observed, with the first chick hatching on the 31st May, and the fledging of both chicks on the 12th and 13th June, respectively (9).

Conservation ( Inglês )

fornecido por Arkive
Despite the precarious status of the Negros bleeding-heart, there are very few specific conservation measures in place. It occurs within the Mount Canlaon Natural Park on Negros, and possibly also in the North Negros Forest Reserve. However, the North Negros Forest Reserve receives virtually no protection at present (7). On Panay, it occurs in the North West Panay Peninsula, which was proclaimed a Protected Area in 2001. Forest Rangers, of the Philippine Endemic Species Conservation Project (PESCP), patrol this area, and the northern part of the Central Panay Mountain Range, destroying snares and curbing illegal logging. PESCP also ran an Airgun-for-Rice programme as an intervention against hunting in the region; a large number of airguns were destroyed as a result of the programme (5) (10). Several conservation actions are required to reduce the risk of extinction to the Negros bleeding-heart, primarily the protection of key areas where this species occurs, and the increased protection of existing reserves and parks. Searches for the Negros bleeding-heart should be undertaken, to identify important forest fragments where it occurs, and the initiation of reforestation activities is also recommended (7). Unlike the Mindanao bleeding-heart this species is not yet bred in captivity. Some organizations advocate the captive breeding of the Negros bleeding-heart to prevent its extinction, with the final aim of releasing the birds back into the wild once their habitat has been secured (6). However, given sufficient habitat protection and law enforcement on Panay, it is believed that the species can be saved through pure in situ operation (5).

Description ( Inglês )

fornecido por Arkive
This peculiarly coloured pigeon is one of five bleeding-heart species, called so because of the large blood-red patch on the breast (2) (3). The 'bleeding-heart' varies slightly in shape and colour among species; the Negros bleeding-heart having a narrower red patch on its white breast than other bleeding-hearts (2). It has dark chestnut upperparts with a reddish-purple gloss, creamy-buff underparts, and an iridescent green head and neck (4). It also has a noticeable greyish-white band across its folded wing (2).

Threats ( Inglês )

fornecido por Arkive
Like the four other bleeding-heart species that occur in the Philippines, the Negros bleeding-heart is greatly threatened by the destruction of its habitat. In 1988, only four percent of forest cover remained on Negros, and Panay held on to just eight percent of its forest. This alarming loss is due to the clearance of forest for agriculture, timber and charcoal-burning, and these activities remain a serious threat to the remaining fragments of forest. The effect of this devastating habitat destruction is aggravated by local trapping and hunting of the Negros bleeding-heart for food and, presumably, for the cage-bird trade (1). As a result of these threats, the extremely small population of Negros bleeding-hearts, (estimated to be between 50 and 249 individuals), is still declining (4), which makes it extremely vulnerable to extinction.

Negros-Dolchstichtaube ( Alemão )

fornecido por wikipedia DE

Die Negros-Dolchstichtaube (Gallicolumba keayi), auch als Negrostaube bezeichnet, ist eine sehr seltene Art der Taubenvögel. Sie kommt ausschließlich auf den Philippineninseln Negros und Panay vor. Von der IUCN wird die Art als vom Aussterben bedroht eingeordnet (critically endangered). Grund der Ursache ist, dass die Negros-Dolchstichtaube nur ein sehr kleines Verbreitungsgebiet hat. Kontinuierliche Rodungen haben dazu geführt, dass ihr Lebensraum stark fragmentiert ist und weiter zurückgeht.[1] Der Bestand wird auf nur noch 50 bis 250 Tauben geschätzt.

Zeichnung von John Gerrard Keulemans

Erscheinungsbild

Die Negros-Dolchstichtaube erreicht eine Körpergröße von 25 Zentimetern.[2] Der Scheitel und der Mantel sind schillernd dunkelgrün, das übrige Gefieder der Körperoberseite ist kastanienbraun mit einem purpurfarbenen Schimmer. Die Körperunterseite ist weiß. Auf jeder Seite der Brust findet sich ein großer grüner und glänzender Fleck. Diese Flecken umschließen einen länglichen, leuchten orangeroten Brustfleck. Der Unterbauch ist weiß. Die Flanken und die Unterschwanzdecken sind orangefarben überwaschen. Die Schwanzfedern sind grau mit einem schwarzen Endband. Die Beine sind rot.

Verbreitung, Lebensraum und Bestand

Die Negros-Dolchstichtaube ist eine endemische Art der Inseln Panay und Negros. Im Nordwesten Panays wurde sie zwei Mal 1997 beobachtet. Panay ist noch etwas stärker bewaldet als Negros, so dass hier mehr Möglichkeiten bestehen, dass sich Populationen halten. Auf Panay scheint sie auch noch zu brüten. Auf Negros war die Negros-Dolchstichtaube noch im 19. Jahrhundert eine verhältnismäßig häufige Art. Sie wurde jedoch schon in den 1930er Jahren sehr selten. Seit den 1980er Jahren wurde sie auf Negros nur noch im Gebiet des Mount Kanlaon Natural Parks beobachtet, obwohl eine mehrwöchige Expedition nach dieser Art gezielt suchte. Vereinzelte weitere Sichtungen stammen auch aus dem Northern Negros Natural Park. Es scheint noch mehrere kleine Populationen im Süden von Negros, im Balinsasayao Twin Lakes Natural Park zu geben.[1]

Die Negros-Dolchstichtaube war zumindest auf Negros eine Art des Tieflands. Hier wurden jedoch alle geeigneten Lebensräume zerstört. Beobachtet wurde die Negros-Dolchstichtaube nur noch in Höhenlagen zwischen 900 und 1.000 Metern und sie kommt möglicherweise auch noch in Höhenlagen von 1.200 Metern über NN vor. Auf Panay wurde sie in Höhenlagen von 600 Metern beobachtet.[3]

Verhalten

Über die Lebensweise der Negros-Dolchstichtaube liegen bislang keine Studien des Verhaltens vor. Auch Beobachtungen an in Gefangenschaft gehaltenen Vögeln fehlen. Sie sucht nach ihrer Nahrung auf dem Boden. Ihre Fortpflanzungsbiologie ist unbekannt.[4]

Negros bleeding-heart pigeon ( Inglês )

fornecido por wikipedia EN

The Negros bleeding-heart pigeon (Gallicolumba keayi) is endemic to the Philippines where it is found on the islands of Negros and Panay. It is critically endangered; continuing rates of forest loss on the two islands where it occurs suggest that it will continue to decline. The population is estimated to be just 50 - 249 mature individuals. The species has an extremely small, severely fragmented population.[3] The bird is listed as an EDGE species under the analysis of the Zoological Society of London.[4]

It is considered one of the Western Visayas Big 5 which includes the Walden's hornbill, Visayan spotted deer, Visayan hornbill and the Visayan warty pig.[5]

Description

Ebird describes it as "A very rare medium-sized ground dove of foothill forest floor on Negros and Panay. Iridescent greenish-blue on the head and sides to the chest, scaled on the upper back, with brownish flight feathers. White underparts narrow from the throat down the chest to the belly. Obvious white crescents mark the wing and sides of the chest. Note the red "bleeding heart" in the center of the chest. Unlikely to be mistaken if seen well. The only other dove likely to flush from the ground would be Asian emerald dove. Song is a short, accelerating series of low notes."[6]

25 cm (10-in) is its total length. Ground-feeder but roosts and nests on bushes or vines; seen in pairs in a flock. Birds with enlarged gonads recorded in April and May and a recent fledgling obtained on May 3.[7]

It has been recorded nesting in March - June with chicks fledging after only 12 days, apparently as an adaptation to the vulnerability of their open and low nests in epiphytic ferns. Nests appear to be regularly predated. The species predominantly feeds on plant material, although there is some potential evidence to suggest that they may also occasionally feed on ground invertebrates.

Habitat and conservation status

The Negros bleeding-heart lives primarily in primary forest up to 1,200 meters above sea level. They are sensitive to habitat disturbance and do not tolerate second growth as well but there are some sparse records..

It is critically endangered with the population estimated to be 50 -249 mature individuals remaining. They are threatened by hunting for food, trapping for the pet trade and habitat loss .[8] Continuing rates of forest loss on the two islands where it occurs suggest that it will continue to decline. By 2007, Negros and Panay had a 3% and 6% remaining forest cover with most of this being higher elevation forest where this bird does not thrive in. Despite already paltry forest cover, deforestation still continues thanks to both legal and illegal logging, conversion into farmland, mining and road development. Trapping and hunting for food and, presumably, for the cage-bird trade constitute other threats.

It was bred for the first time in captivity in 2007 at the Center for Tropical Conservation Studies. As of 2013, the captive population totals 18 individuals, 14 of which have been bred from birds confiscated from the illegal bird trade. Captive breeding is being undertaken by the Talarak Foundation supported by the Philippines Biodiversity Conservation Foundation. There are plans for future reintroductions.

Conservation actions proposed include fieldwork and surveys in areas where they have been reported and other areas with suitable habitats. Provide protection for existing habitats like the Northern Negros Forest reserve. Encourage reforestation activities with an emphasis on native trees. Create education and awareness campaigns to aid in conservation and prevent hunting and the pet trade.[9]

Gallicolumba keayi ( Italiano )

fornecido por wikipedia IT

La colomba pugnalata di Kaey (Gallicolumba keayi (W. E. Clarke, 1900)) è un uccello della famiglia Columbidae, endemico delle Filippine.[2]

Distribuzione e habitat

L'areale della specie è ristretto alle isole di Panay e Negros, nell'arcipelago delle Filippine[1].

Conservazione

La popolazione residua è stimata in 70-400 esemplari; in base a tale dato Gallicolumba keayi è classificata dalla IUCN Red List come specie in pericolo critico di estinzione (Critically Endangered)[1].

Nel 1997 esemplari vennero registrati in due siti nella parte nordoccidentale dell'isola di Panay e precedentemente, all'inizio degli anni Novanta, erano stati osservati da locali in cinque siti; da allora sono stati osservati nidi nelle stesse aree fino all'anno 2005. Sull'isola di Negros, la G. keayi era piuttosto comune nel corso del XIX secolo, ma cominciò a divenire rara dagli anni trenta tanto che negli anni ottanta veniva registrata solo presso le fonti termali di Mambucal, sulle pendici del vulcano Kanla-on. Studi più recenti riportano di avvistamenti nella parte meridionale di Negros, ma con ogni probabilità la specie risulterebbe estinta nella parte nord dell'isola che conserverebe, come a Panay, solo alcune centinaia di esemplari.[1]

Parte del suo areale ricade all'interno del Parco naturale del monte Kanla-on, dove la specie è protetta[3].

De vogel is gemiddeld 30 cm, de vleugellengte is 15 cm. De negrosdolksteekduif lijkt op de Mindoro-dolksteekduif en de gewone dolksteekduif en is ook endemisch voor de Filipijnen. Zij hebben als meest opvallende kenmerk een rode vlek op de verder lichte borst, waarbij het lijkt alsof ze met een dolk gestoken zijn. De "bloedvlek" van de negrodolksteekduif is langer en smaller. De kruin, nek, mantel en binnenste kleine vleugeldekveren zijn iriserend groen. Er loopt een brede lichtgrijze band over de opgevouwen vleugel.De rest van de vleugel en de bovenkant van de staart zijn donkerbruin.[2]

Verspreiding en leefgebied

Op Negros kwam de soort tot de 19e eeuw veelvuldig voor. Sinds 1980 is de soort hier nog slechts op één locatie waargenomen. De soort komt nog voor op Panay. Het leefgebied is onaangetast regenwoud, waar de vogel rondscharrelt op de bosbodem. De soort is rond 2005 nog aangetroffen in zwaar door houtkap aangetast bos op 800 tot 1200 m boven de zeespiegel.[2]

Voortplanting

Men heeft negrosdolksteekduiven met vergrote gonaden waargenomen in april en mei. Een net geboren jong is waargenomen in de maand mei. Over het nest en de eieren in het wild is niets bekend.[3]

Status

De negrosdolksteekduif is erg zeldzaam. BirdLife International schatte hun aantal in 2001 op 70 tot 400 exemplaren. In 1988 was op Negro nog slecht 4% en op Panay nog maar 8% over van het oppervlak aan primair regenwoud. Deze aantasting van het leefgebied door houtkap, houtskoolwinning en omzetting van bos in gebied voor agrarisch gebruik gaat door. Daarnaast is er stroperij. Daardoor is de kans op uitsterven aanwezig. Om deze redenen staat deze soort als ernstig bedreigd (kritiek) op de Rode Lijst van de IUCN.[1]
