maxwell's black weaver Ploceus albinucha

An entirely black forest weaver with piercing white eyes found in low-elevation and foothill forests, in small groups or with mixed-species flocks, sometimes with other species of weaver. Occasionally forms much larger groups, and will sometimes nest in large single-species or mixed-species colonies. Birds in the western part of the range have a silver nape, but birds in the east are wholly black. Western populations are nearly identical to co-occurring populations of Vieillot’s Weaver, but have a thinner, pointier bill and prefer more forested habitats. Vocalizations include dry chatters and soft mechanical rasps, sometimes given in complex combinations.
