Subspecies

Monotypic species

Genus

The tinamous of the genus Crypturellus are usually notoriously difficult to see. Most species of this family are polygamous, with the smaller males performing the domestic tasks and the eggs are beautifully coloured. Tinamous exhibit exclusive male parental care. This type of care is rarely found in birds and only in tinamous is present in all species of the order. In polygynandrous species, males accumulate eggs from several females in at least two different ways: in some species females form stable groups and cooperate to lay the clutch for a male, sometimes even laying replacement clutches together. In other species, multiple females lay eggs in a nest, but they
do not form associations or travel together before or after being attracted by the male.

Physical charateristics

The Undulated Tinamou is approximately 28-30 cm in length. It is overall brownish tinged grey to various extend, and has a strong, black barred to faint vermiculated pattern on the back and neck (for example, while C. u. undulatus is relatively rich brown and strongly barred, C. u. yapura is darker, more grey-tinged and only has faint vermiculations). It has a whitish throat, and the remainder of its underparts are olive-grey to buff with dark vermiculation on its lower flanks and vent. Its bill is black above and grey below. The legs and feet are grey, dull yellow or greenish.

Range

South America : Amazonia, Southcentral. The Undulated Tinamou is a ubiquitous species of river forest and second growth in the Amazon basin but also occurs in the drier tropical and subtropical regions of south central and eastern South America

Habitat

The Undulated Tinamou occurs at altitudes of up to 900m. It occurs in a wide range of wooded habitats, ranging from dense, humid Amazonian forests, to dry, relatively open savanna-woodland

Reproduction

Nest is a small depression in the ground, clutch size is 4-5 egss

Feeding habits

A ground-foraging omnivore, the Undulated Tinamou feeds on small fruits, seeds, and insects

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
