The yellow-hooded blackbird (Chrysomus icterocephalus) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Brazil, Colombia, French Guiana, Guyana, Peru, Suriname, Trinidad, and Venezuela. It has been recorded as a vagrant on Aruba, Bonaire, and Curaçao. In addition, there is a small population in extreme eastern Panama and a previously misidentified specimen from Barbados.
The yellow-hooded blackbird is about 17 to 19 cm (6.7 to 7.5 in) long. Males weigh an average of 35.9 g (1.3 oz) and females average 26.8 g (0.95 oz). The species is sexually dimorphic. Adult males of the nominate subspecies have a bright yellow head, throat, neck, and upper breast except for black lores. Ther rest of their plumage is glossy black. Adult females of the nominate subspecies have a yellow supercilium, throat, and upper breast. Their crown and the rest of their face are citrine. Their upperparts are dull grayish olive with dusky streaks. Their wings and tail are a darker brownish olive. Their underparts are mostly olive with a somewhat olive-streaked brownish belly. Adult males of subspecies C. i. bogotensis are like the nominate. Adult females are darker than the nominate. Their head is less yellowish overall. They have a blackish mask from the lores to the ear coverts and a brighter yellow supercillium that wraps around behind the ear coverts to meet a yellow upper breast. Juveniles are similar to adult females but are duller, have less yellow on the head, paler upperparts, and faintly streaked buffish underparts. Both sexes of both subspecies have a dark brown iris and black legs and feet. Males have a black bill; females' bills often have a pale base to the mandible.
