Gallicolumba is a genus of ground-dwelling doves
which occur in rainforests on the Philippines, Indonesia, and in the Pacific
region. This include the Ground-doves from the Pacific islands and the Bleeding-hearts
known from the Philippines. The latter are named thus for a vivid-red patch on
the breast which looks startlingly like a bleeding wound in some species; it
reminded naturalists of a dagger stab. The diet of doves of this genus consists
of fruits and seed.
Systematics
Currently about 20 species
are extant. Of the larger genera of Columbidae, Gallicolumba is the one
most affected by extinction. 3-4 species have disappeared since the 18th
century, and most of the remaining are decreasing in numbers, threatened with
extinction or have lost subspecies due to habitat destruction, invasive
species, or overhunting. In addition, there are several species never studied
alive but known from subfossil bones. These became extinct during the human
settlement of the Southern Pacific region (c. 3000 BC - 1400).
Bones of Gallicolumba
ist distinct enough to usually recognize this genus with ease. Still, the
evolutionary affiliation of extinct species is often uncertain. Especially,
most extinct Polynesian taxa occur in the area where the white-headed (G.
jobiensis, G. erythroptera) lineage and the Melanesian expansion
that brought about G. sanctaecrucis and G. stairi, and possibly G.
rubescens, would have met.
