holub kovový Ducula aenea

Stately large pigeon, predominantly pearl gray with deep green wings and back. Birds of Sulawesi and the north Philippines have a gingery-orange nape patch. Inhabits forested areas from the lowlands up into the foothills, including edge areas and second growth near human habitation. Very vocal, with a wide repertoire: most common call is a throaty “rrruh-RUOOHH,” but various extended or pitch-altered versions of it are given as well.
