Nocturnal Curassow

The nocturnal curassow is the smallest curassow at 50 to 57.5 cm (1.6 to 1.9 ft) long. One bird weighed 1,250 g (2.8 lb). It is also unique with its mostly rufous and chestnut plumage, as other curassows are mostly black. Its crest is flat and blackish, its ventral area buffy, and the tips of its tail feathers are paler than the rest. Its brownish-orange eye is surrounded by bare skin, greenish-yellow above and black below. The bill is reddish-orange and the legs gray. Voice: The nocturnal curassow sings only at night, primarily on clear dark nights in dry weather. Its song is "a series of seven, low-pitched, highly resonant notes...rendered 'hmm-hmm-hmmmm, hmm hmm-hmmm, hmmph!'." Sometimes several birds will counter-sing.
