About Aramides ypecaha (Vieillot, 1819)
Aramides ypecaha, commonly known as the giant wood rail, is 41 to 45 cm (16 to 18 in) long, and may reach up to 53 cm (21 in) in total length. Two recorded female specimens weighed 640 g (23 oz) and 765 g (27 oz). Males and females have identical appearance. Adult giant wood rails have a large mustard yellow bill, red eyes, and red legs and feet. The area from their face to upper chest is bluish gray, with a white chin. The back of their neck is rust red, their back is olive, and their uppertail coverts and tail are black. Their flanks, breast, and belly are brownish pink. Juvenile plumage for this species has not been described. The giant wood rail occurs in eastern Bolivia, east-central and southeastern Brazil, Paraguay, Uruguay, and northeastern Argentina. It is a lowland bird that inhabits wet landscapes including marshes, lightly wooded swamps, gallery forest, and fields and pastures near water and cover.
