ID tip
Male crested oropendolas of the nominate subspecies P. d. decumanus average 47 cm (19 in) long and females 37 cm (15 in). Males weigh about 285 g (10 oz) and females about 160 g (5.6 oz). Adult males have long feathers on their nape that form a crest. They are mostly a slightly glossy black with a chesnut rump, uppertail coverts, and undertail coverts. Their central pair of tail feathers are black and the rest yellow. Adult females are overall duller than males; they are brownish tinged rather than pure black and have a minimal crest. Voice: The male crested oropendola's display song "usually starts with low-pitched liquid notes, accelerates into variable and complex rattling crescendo, and ends with 2–3 seconds of rhythmic wing-flaps". One description calls it "very complex, including very high, rapid, staccato flutes and liquid curls".
