Biology

Like most birds, these curassows roost in trees (5). However, they spend most of the day foraging on the ground, usually in pairs or small family groups of three or four birds (5), which may or may not include more than one adult female (6). This bird feeds on small fish, insects, aquatic crustaceans and other small animals, which are sought in flooded forest and along overgrown river-shores (2) (7). Fruit and seeds are also eaten, although the proportion of these in the diet appears to depend on seasonal abundance (2). June is the peak month for male courtship displays and nesting (2) (6), with males displaying by laying their head back, raising their tail to show the white of the under-tail coverts, and trotting in circles around the female. A mated pair will usually build the nest together, but males may sometimes build a nest on their own and then go searching for a female with which to breed (5). Females are thought to incubate the two to six eggs alone, while the male guards the nest and territory, although conflicting reports exist (5) (6). Chicks have been observed in July (2), and they usually remain with their parents until they are fully grown (5).
