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.
The Cinereous Tinamou is recognized by its smoky-grey with reddish-brown crown and nape. Its dark phase is uniformly in sooty brown color. This species has a loud distinctive whistle heard mainly at dawn and dusk.

South America : Amazonia
Dense undergrowth of tropical rainforest, with patches of Savannah and scattered trees.
Breeds all year around, nest is a small ground scrap between tree roots. Clutch size 1-3 eggs, incubated by male, young are cared for by the male.
Mostly berries, fruit and seeds, but also insects (ants) and invertebrates are eaten. Feeds by walking forest ground.
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.
Common breeder in Surinam, the most abundant Tinamou in the coastal area. It an be found in cocoa and coffee plantations but mostly in wet forest.
Sedentary in all of its range, but not well known
