Appearance
This is a slim bird, 8.7 inches (22 cm) long and weighing 1.5 oz (43 g), with a long tail and thin decurved bill. It has mainly black plumage, apart from a bright yellow crown, rump, thighs and wing epaulets. The sexes are similar, but the juvenile bird is dark brown rather than black, with duller yellow patches.Distribution
The mochique oriole breeds from eastern Colombia, Venezuela, Trinidad and the Guianas, and south to eastern Ecuador, Paraguay and northern Brazil. The Trinidadian population may have originated from recent colonization or escapes.Behavior
The song of the moriche oriole is a squeaky whistling heaaa-wheeooo-heaaa. This is an often-conspicuous species near its favoured tree, and usually occurs singly or in pairs.Habitat
It is most common from sea level up to 1,600 ft (490 m) ASL, but here and there it reaches up to around 3,300 ft (1,000 m) in the eastern foothills of the Andes, which mark the western border or its range.References:
