The little tinamou (Crypturellus soui) is a species of tinamou. It is found in Central and South America, as well as on the Caribbean island of Trinidad. [4]
Crypturellus is formed from three Latin or Greek words. kruptos meaning covered or hidden, oura meaning tail, and ellus meaning diminutive. Therefore, Crypturellus means small hidden tail. [5]
The little tinamou is one of 21 species in the genus Crypturellus , the most species-rich genus of tinamous. All tinamous are in the family Tinamidae, and in the larger scheme are also palaeognaths, a group that includes the more widely known flightless ratites such as ostriches and emus. Unlike the ratites, though, tinamous can fly, although in general they are not strong fliers. All palaeognaths evolved from flying ancestors. [6]
It is a resident breeder in tropical lowland forests, rivers-edge forests, lowland evergreen forest, secondary forest, [3] and lowland shrublands at an altitude of 2,000 m (6,600 ft). They are also fairly successful utilizing cleared forests and plantations or farmed land. [1]
Little tinamou are shy, secretive, and pair-solitary animals. Despite their abundance, they are rarely sighted. In the field, they are detected by sound more often than sight. The whistle call is a soft, descending whinny (also a series of single notes, tempo increasing at end) produced by both sexes. They eat seeds, berries, and some insects. They can fly but will run unless flight is necessary. They are highly territorial and will attack when encroached upon if the intruding bird is not their mate. There is evidence that they will maintain the same territory for years.
The breeding season of the little tinamou ranges from May to October. Nests are a small depression in forest floor, sometimes lined with a few leaves at the base of a tree or in dense brush. Females perform courtship behavior and eggs are incubated by males. Male nest attendance is strong, up to 14 days without leaving the nest in one study. They typically lay two glossy dark-purple eggs (up to three have been observed). The size of the egg is approximately 32 to 41 mm (1.3–1.6 in). Young are precocial, and begin pecking the ground on the first day. They can run almost as soon as they hatch. By weeks 3-4 they are capable of full flight. Egg laying begins at one year old.
The little tinamou is approximately 22 to 24 cm (8.7–9.4 in) long and weighs 220 g (7.8 oz). Although it looks similar to other ground-dwelling birds like quail and grouse, it is unrelated to those groups. It has an unbarred sooty-brown plumage which transitions to grey on the head. The foreneck is whitish. While the underside of both male and female is cinnamon buff, the female is a lighter shade. The legs can be grey, olive, or yellow. Both male and female are almost tailess.
The IUCN list the little tinamou as Least Concern, [1] with an occurrence range of 9,500,000 km2 (3,700,000 sq mi). [7]
Tinamous are members of the order Tinamiformes, and family Tinamidae, divided into two distinct subfamilies, containing 46 species found in Mexico, Central America, and South America. The word "tinamou" comes from the Galibi term for these birds, tinamu. Tinamous are the only living group of palaeognaths able to fly, and were traditionally regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation as most closely related to the extinct moa of New Zealand, implying flightlessness emerged among ratites multiple times. Tinamous first appear in the fossil record in the Miocene epoch. They are generally sedentary, ground-dwelling and, though not flightless, when possible avoid flight in favour of hiding or running away from danger. They are found in a variety of habitats, ranging from semi-arid alpine grasslands to tropical rainforests. The two subfamilies are broadly divided by habitat, with the Nothurinae referred to as steppe or open country tinamous, and the Tinaminae known as forest tinamous.
The white-throated tinamou is a species of bird native to the Amazon rainforest of Brazil, northern Bolivia, southeastern Colombia, northeastern Ecuador, eastern Peru and southern Venezuela.
The brown tinamou is a brownish ground bird found in humid lowland and montane forest in tropical and subtropical South America.
The variegated tinamou a type of tinamou commonly found in moist forest lowlands in subtropical and tropical regions of northern South America.
Crypturellus is a genus of tinamous containing mostly forest species. However, there are the odd few that are grassland or steppe tinamous. The genus contains 21 species.
The red-legged tinamou or red-footed tinamou, is a ground-dwelling bird found in the tropics and lower subtropics of northern South America.
Berlepsch's tinamou is a type of ground bird found in moist forest in northwestern Colombia and northwestern Ecuador.
The cinereous tinamou, also known as brushland tinamou, is a type of ground bird found in swamp and lowland forests in northern South America. They have some localized names that have been used by the indigenous people such as in Amazonas where they are called inambu-pixuna, and in Pará, Brazil where they are called nambu-sujo. Also, throughout their range they are called inhambu-preto. Cinereous tinamous have been around for many centuries. They are part of the oldest families of the world today and have fossils discovered dating back tens of millions of years. Their quick reflexes play a role in their ability to survive.
