Slaty-breasted Tinamou

[order] TINAMIFORMES | [family] Tinamidae | [latin] Crypturellus boucardi | [authority] Sclater, 1859 | [UK] Slaty-breasted Tinamou | [FR] Tinamou de Boucard | [DE] Graukehl-Tinamu | [ES] Tinamu Pizarroso, Chinga Pecho Gris (HN) | [NL] Grijsborst tinamoe


Monotypic species


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 Slaty-breasted Tinamou is approximately 25 cm in length. It is a shy and difficult tinamou to be seen on the dark forest floors. Its upperparts are blackish, brown on wings, slaty grey on breast, grey-brown on remainder of underparts with darker barring on flanks and undertail. Its bill is dark above and yellow below, legs reddish orange. It has a hollow -ah-wah- voice with the second syllable downslurred.

Middle America : South Mexico to Costa Rica. This species ranges from southern Mexico from southern Vera Cruz and northern Oaxaca south, to northern Costa Rica. (Mexico, Belize, Guatemala, Honduras, Nicaragua and Costa Rica) It has an estimated global extent of occurrence of 330,000 km2.


The Slaty-breasted Tinamou Crypturellus boucardi, also known as Boucards Tinamou, is a type of Tinamou commonly found in lowlands of moist forest in subtropical and tropical regions up to 1800 m altitude.


Hardly known. In the breeding season it establishes a small territory in its home range, attracting two to four females to lay in a nest at the base of a tree or in thick vegetation. Male incubates the eggs. Male attendance at the nest was reported for Slaty-breasted Tinamou (Crypturellus boucardi). The single male observed incubating remained in contact with the eggs 91.4% of the time, taking one long recess every 2 days in the middle of the afternoon, and turning the eggs 5-10 times a day after standing up.

Feeding habits

Feeds on fruits and seeds, tossing leaves aside with its bill in its search. It takes insects, including ants and termites.

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 may be moderately small to large, 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.
