Chestnut-headed oropendola : ウィキペディア英語版 | Chestnut-headed oropendola
The chestnut-headed oropendola (''Psarocolius wagleri'') is a New World tropical icterid bird. The scientific name of the species commemorates Johann Georg Wagler, who established ''Psarocolius'', the oropendola genus. ==Description== The male is long and weighs ; the smaller female is long and weighs . 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. The distinctive songs of the male include a gurgle followed by a crash ''guu-guu-PHRRRRTTT''. Both sexes have loud ''chek'' and ''chuk'' calls.
