About Gallicolumba luzonica (Scopoli, 1786)
Gallicolumba luzonica is a medium-sized ground dove. The upper surfaces of the Luzon bleeding-heart are slate grey, but can appear purple, royal blue, or bottle-green under different lighting conditions due to iridescence. Its wings have black bands, while its belly and underwing areas are buff or chestnut. It has a white throat, chest, and belly; its most distinctive feature is the bright red "bleeding heart" marking at the center of its chest, surrounded by a faint pink area that looks like a fading blood stain. This species shows slight sexual dimorphism: males are generally larger and have a more prominent red patch, while the patch is slightly duller in females. Its body shape is typical for its genus, with a round body, short tail, and long legs. Its call is described as a repeated, single, mournful coo that lasts 1 to 2 seconds and rises and falls in pitch. It also has a gruff display call made of 5 or 3 notes. In terms of behaviour and ecology, the Luzon bleeding-heart feeds on seeds, berries, and grubs. It is shy, secretive, and very quiet, and rarely leaves the ground except when nesting. Unlike other bleeding-heart doves, this species typically lays two eggs per clutch. Nesting has been recorded in the months of May and June.
