Undulated Tinamou

Overview

The undulated tinamou (Crypturellus undulatus) is a small, secretive ground bird found across a wide range of wooded habitats in eastern and northern South America. It is the closest and smallest living relative of other ratites, such as the emu, ostrich, and kiwi, and is classified as a Least Concern species by the IUCN.

Identification

• Measures approximately 28–30 cm in length and weighs around 300 g.
• Plumage varies by subspecies but is generally brownish tinged with grey, featuring a strong black barred or vermiculated pattern on the back and neck.
• Underparts consist of a whitish throat, with olive-grey to buff lower flanks and vent that display dark vermiculation.
• Possesses a black bill (grey below) and legs that are grey, dull yellow, or greenish.
• Song is a deep, three- or four-noted whistle often described as com-pra pan or eu sou jáo.

Habitat

This species inhabits a diverse array of wooded environments at altitudes up to 1,400 m, ranging from dense, humid Amazonian forests to dry, relatively open savanna-woodland. While the majority of its range lies within the Amazon Basin, significant populations occupy drier habitats such as the Cerrado region in eastern Brazil. It is generally considered a resident, though minor seasonal movements between habitats occur locally.

Diet

The undulated tinamou feeds on small fruits, seeds, and insects. The provided text does not specify detailed foraging techniques beyond its ground-dwelling nature.

Did you know?

As a member of the family Tinamidae, the undulated tinamou is a ratite, making it a distant relative of flightless birds like the emu and ostrich; however, unlike these larger relatives, it retains the ability to fly weakly, typically using flight to perch on branches when fleeing threats.
