Gallicolumba luzonica (Scopoli, 1786) |

The Luzon bleeding-heart (Gallicolumba luzonica) is one of a number of species of ground dove in the genus Gallicolumba that are called "bleeding-hearts". 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.
On its upper surfaces, the Luzon bleeding-heart is slate grey in colour, but because it is iridescent, it can appear to be purple, royal blue, or bottle-green, and the apparent colour varies with lighting conditions. The belly and under wing areas are buff or chestnut. As in most pigeons, there is little sexual dimorphism; males tend to be larger and have a more pronounced red patch, while females are slightly duller. The body shape is typical of the genus, with a round body, a short tail and long legs.
The species is endemic to the island of Luzon, Philippines. It has a local name of puñalada.
Three subspecies are known. Gallicolumba luzonica luzonica is found on the central and southern parts of the large island of Luzon, and the neighbouring small Polillo Islands. The subspecies of Gallicolumba luzonica griseolateralis is found on the Northern part of Luzon while Gallicolumba luzonica rubiventris is found exclusively on Catanduanes Island. Gallicolumba luzonica rubiventris or known as Catanduanes bleeding-heart has only single collected specimen in 1971; this subspecies is very rare as it is believed to be near extinction or already extinct.
It lives in primary or secondary forest, and can be found at altitudes varying from sea level up to 1400 metres. 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.
