The Luzon bleeding-heart, bleeding-heart dove, bleeding-heart pigeon or punay (Gallicolumba luzonica) is one of a number of species of ground dove in the genus Gallicolumba, know as "bleeding-hearts". The native name in Tagalog is punay. It is also known as paloma de punalada 'stabbed pigeon'. The Luzon bleeding-heart is the species in which the "blood" feature is most pronounced, with the reddish hue extending down the belly, furthering the illusion of blood having run down the bird's breast.

Description

On its upper surfaces, the Luzon bleeding-heart is slate grey in color, but because of its iridescence, it can appear to be purple, royal blue, or bottle-green with varying lighting conditions. On their wings are black bands, while their belly and under wing areas are buff or chestnut.

As is with most pigeon species, there is little sexual dimorphism; males tend to be larger and have a more pronounced red patch, while in the females it is slightly duller. The body shape is typical of the genus, with a round body, short tail, and long legs.

Distribution

The Luzon bleeding-heart is endemic to the island of Luzon in the Philippines where the locals call it Puñalada. It lives in primary or secondary forests, and can be found at altitudes varying from up to 1400 meters above sea level. They eat seeds, berries and grubs. They are shy and secretive, and very quiet, and rarely leave the ground except when nesting. Unlike the other bleeding-hearts, they usually lay two eggs in each clutch.

Three subspecies of the Luzon bleeding-heart are known: Gallicolumba luzonica luzonica, Gallicolumba luzonica griseolateralis, and Gallicolumba luzonica rubiventris.

Gallicolumba luzonica luzonica is found on the central and southern parts of the island of Luzon, and the neighboring Polillo Islands, while Gallicolumba luzonica griseolateralis is found on the northern part of the island. Gallicolumba luzonica rubiventris has been found exclusively on the island of Catanduanes where a single specimen was collected in 1971; this subspecies is very rare and believed to be near extinction or already extinct.

Conservation status

As of 2016, the Luzon bleeding-heart is listed as Near Threatened by the IUCN, due to the species being threatened by habitat loss and fragmentation through deforestation for timber extraction and agricultural lands. It is also commonly trapped as a pet for its striking plumage. [1]

The Tanna ground dove, also known as Forster's dove of Tanna, is an extinct dove species. Its taxonomic affiliation is uncertain but at its first scientific discussion by Johann Georg Wagler in 1829 it was classified into the genus Gallicolumba ; its closest relative is possibly the Santa Cruz ground dove. It was endemic to the Pacific island of Tanna, Vanuatu. Forster records a native name mahk, almost certainly from the Kwamera language.

<i>Gallicolumba</i> Genus of birds

Gallicolumba is a mid-sized genus of ground-dwelling doves which occur in rainforests on the Philippines. Local name 'punay' which is a general term for pigeons and doves. They are not closely related to the American ground doves genus. Rather, the present genus is closest to the thick-billed ground pigeon.

The thick-billed ground dove is an extinct dove species of the family Columbidae.

The Sulu bleeding-heart or Tawitawi bleeding-heart is a species of bird in the pigeon and dove family, Columbidae. It is endemic to the island of Tawi-Tawi and its surrounding islets in the Philippines' Sulu Archipelago. This species is known only from two specimens collected in 1891, and has not been recorded with certainty since. It lives in primary and secondary forests that have a closed canopy. The Sulu bleeding-heart is a medium-sized pigeon with a short tail. Bright metallic green feathers stretch from the forehead and crown down to the mantle and sides of the breast, where they surround a large, pale orange breast spot with diffuse edges that gives the species the name "bleeding-heart". The lower wings and back are varying shades of brown, and the throat and chest are largely white. The belly is an ashy-gray.
