The Negros bleeding-heart (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]

Contents

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]

It is illegal to hunt, capture or possess Negros bleeding-hearts under Philippine Law RA 9147. [6]

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." [7]

Among the other bleeding hearts, this species is distinguished by its long vertical "heart", bright green color, distinguished white "V" shaped wingbar and breast-side bar. [8]

This species is monotypic.

Behaviour and ecology

25 cm (10-in) is its total length; individually or in pairs. Ground-feeder but roosts and nests on bushes or vines The species predominantly feeds on plant material, although there is some potential evidence to suggest that they may also occasionally feed on ground invertebrates.

Birds with enlarged gonads recorded in April and May and a recent fledgling obtained on May 3 In captivity, the male's heart appears to get brighter and more red during breeding season. 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.

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 . [9] 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 constitute other threats.

It was bred for the first time in captivity in 2007 at the Center for Tropical Conservation Studies. The captive population is currently stable, with a number of captive populations in the Philippines such as Silliman University. [6] [10] In 2021, Talarak Foundation sent six birds to Bird Paradise in Singapore to start an ex-situ population with the aim to expand the captive population outside of the Philippines. The successful captive breeding has resulted in the Talarak Foundation releasing captive-bred individuals in the Bayawan Nature Reserve., supported by Bristol Zoo [11] and Toledo Zoo. [12]

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. [13]

The Luzon bleeding-heart, bleeding-heart dove, bleeding-heart pigeon or punay is a species of ground dove in the genus Gallicolumba, known as "bleeding-hearts" due to their distinctive red patch on its chest. It was also known as paloma de punalada 'stabbed pigeon' but is nowadays more commonly referred to as just punalada. The Luzon bleeding-heart is the species in which the "blood" feature is most pronounced, while the Mindanao bleeding-heart does have a larger red patch, the Luzon bleeding-heart has a reddish hue extending down the belly, furthering the illusion of a blood stain. It is threatened by habitat loss and hunting for the pet trade and for meat.

<span class="mw-page-title-main">Visayan spotted deer</span> Species of deer

The Visayan spotted deer, also known as the Visayan deer, the Philippine spotted deer or Prince Alfred's deer, is a small, endangered, primarily nocturnal species of deer found in the rainforests of the Visayan Islands of Panay and Negros. It once was found across other islands, such as Cebu, Guimaras, Leyte, Masbate, and Samar. It is one of three endemic deer species found in the Philippines, although it was not recognized as a separate species until 1983. An estimated 2,500 mature individuals survived worldwide in 1996, according to the IUCN; today’s surviving wild number is uncertain. The diet of the deer, which consists of a variety of different types of grasses, leaves, and buds within the forest, is the primary indicator of its habitat. Since 1991, the range of the species has severely decreased and is now almost co-extensive with that of the Visayan warty pig.
