Grey-headed chachalaca

The grey-headed chachalaca (Ortalis cinereiceps) is a member of an ancient group of birds in the family Cracidae, which includes chachalacas, guans, and curassows. It is found from Honduras to Colombia.

The grey-headed chachalaca is a medium-sized bird, similar in general appearance to turkeys, with a small head, long strong legs, and a long broad tail. They are 48 to 58 cm (1.6 to 1.9 ft) long and weigh 490 to 540 g (1.1 to 1.2 lb). They have fairly dull plumage, grayish brown above and paler below. The head is dark grey with a red dewlap and the blackish tail is tipped with buff. Their primary flight feathers are bright chestnut. Juveniles are browner overall, especially on the head.
