Male Great Curassow, Corcovado National Park, Costa Rica
Locals in Costa Rica refer to the great curassow as the jungle turkey (at least that’s what my guide kept calling them). They are very large birds that forage on the ground. Like many birds, they are monogamous, and are usually encountered in pairs. The male and female are quite different looking. This one is a male. The females have distinct ornamentation on their heads and are reddish brown of body.
