Chestnut-headed Oropendola

Psarocolius wagleri

Rather large, dark, yellow-tailed bird of humid evergreen forest and edge in tropical lowlands. Where present, colonies of large pendulous nests adorn tall trees. Often in flocks, usually in forest canopy at fruiting trees. Male is much larger than female, but sexes look similar, with a dark, rich brown head and body, blackish upperparts, pale yellowish bill, and bold yellow tail sides. Flight much quicker than larger Montezuma Oropendola, with deep, rather swooping wingbeats that produce a rushing sound.

The male is 35 cm (14 in) long and weighs 225 g (7.9 oz); the smaller female is 28 cm (11 in) long and weighs 125 g (4.4 oz). The wings are very long. Adult males are mainly black with a chestnut head and rump and a tail which is bright yellow apart from two dark central feathers. The iris is blue and the long bill is whitish. Females are similar, but smaller and duller than males. Young birds are duller than adults and have brown eyes. The populations south of an area around the border of Honduras and Nicaragua are sometimes separated as a subspecies P. w. ridgwayi, but the separation of this form has been questioned.<p>The distinctive songs of the male include a gurgle followed by a crash guu-guu-PHRRRRTTT. Both sexes have loud chek and chuk calls.
