Crypturellus duidae SA Venezuela, Colombia

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 Grey-legged Tinamou is approximately 30 cm in length. It is dark brown above with finely barred black on its lower back, it is rufous below, has tinged grey on its upper breast, the sides of its belly are banded buff, its head and neck are rufous, its throat white, and its legs are greyish. The female is darker on her lower back with narrow light buff barring

Conservation

This species has a very 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.
