Rufous-vented Chachalaca

Ortalis ruficauda

Large586 gWoodland

These are medium-sized birds, similar in general appearance to turkeys, with small heads, long strong legs and a long broad tail. They are typically 53–58 cm long; the female weighs 540g and the larger male 640g. They have fairly dull plumage, dark brown above and paler below. The head is grey, and the brown tail is tipped rufous or white depending on race. Voice: As other chachalacas, the rufous-vented chachalaca is a very noisy species, preferring to execute their vocal feats at dawn. The male's call is a loud low ka-ka-rooki-rooki-ka, answered by the female's high-pitched watch-a-lak, which they often repeat several times in a row, in precise synchronization.
