The grey tinamou (Tinamus tao) is a type of ground bird native to South America. Four subspecies are recognised.
All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds. [3]
The grey tinamou has several subspecies:
The gray tinamou is believed to be the largest species among the tinamous. Reported total length is from 41.5 to 49 cm (16.3 to 19.3 in) and possibly as much as 53 cm (21 in). [5] [6] In body mass, males may scale from 1,325 to 1,863 g (2.921 to 4.107 lb), averaging 1,565 g (3.450 lb), and females can weigh from 1,430 to 2,080 g (3.15 to 4.59 lb), averaging 1,636 g (3.607 lb) and possibly weighing as much as 2,300 g (5.1 lb). [5] [7] As suggested by its name, it is mostly grey. The back and head are barred blackish, and its vent is cinnamon. White spotting extends along the head and down the neck.
The grey tinamou is found throughout western and northern Brazil, eastern Ecuador, eastern Peru, Colombia east of the Andes, northern Venezuela, northern Bolivia, and Guyana. [1] [4]
In most of its range it is essentially restricted to humid lowland forests, but in the northern and far western parts of its range it mainly occurs in montane forests. [1] This tinamou has shown the ability to utilize forests that have been cleared by logging. [1] As most other tinamous, its song is commonly heard, but it is shy and only infrequently seen.
Like other tinamous, the male incubates the eggs on the nest that is located in heavy brush on the ground. After incubation, the male will also raise them for the short period of time until they are ready. They eat fruit and seeds from the ground and bushes that are low to the ground. [3]
This species was previously considered by the IUCN to be a Least Concern status, and has a range occurrence of 3,600,000 km2 (1,400,000 sq mi) [1] In 2012 it was uplisted to vulnerable. [8]
The little tinamou is a species of tinamou. It is found in Central and South America, as well as on the Caribbean island of Trinidad.
The red-winged tinamou is a medium-sized ground-living bird from central and eastern South America. Other common names for the species include perdiz grande, rufous tinamou, and ynambu.
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 great tinamou is a species of tinamou ground bird native to Central and South America. There are several subspecies, mostly differentiated by their coloration.
The brown tinamou is a brownish ground bird found in humid lowland and montane forest in tropical and subtropical South America.
The puna tinamou also known as Pentland's tinamou, is a member of the most ancient groups of bird families, the tinamous. This species is native to southern South America. The binomial name of the species commemorates the Irish natural scientist Joseph Barclay Pentland (1797–1873) by Nicholas Aylward Vigors in 1837. The IUCN list this species as Least Concern, with an occurrence range of 590,000 km2 (230,000 sq mi).
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.
The solitary tinamou is a species of paleognath ground bird. This species is native to Atlantic forest of eastern Brazil.
The black tinamou is a species of ground bird found in humid foothill and montane forest in the Andes of South America.
The highland tinamou or Bonaparte's tinamou is a type of ground bird found in montane moist forest typically over 1,500 m (4,900 ft) altitude.
The tawny-breasted tinamou is a type of ground bird found in montane moist forest. Their range is northwestern South America.
The hooded tinamou is a type of ground bird found in forests of Bolivia and Peru.
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.
The undulated tinamou is a species of ground bird found in a wide range of wooded habitats in eastern and northern South America.
The Brazilian tinamou is a type of tinamou found in tropical moist lowland forest in regions of Amazonian South America.
The Tataupa tinamou is a type of tinamou commonly found in dry forest in subtropical and tropical regions in southeastern South America.
Taczanowski's tinamou is a type of ground bird found in the eastern Andes in Peru in the Junín, Cuzco, Apurímac, Ayacucho, and Puno Regions.
The brushland tinamou is a type of tinamou commonly found in high-altitude dry shrubland in subtropical and tropical regions of southern South America.
Nothocercus is a genus of birds in the tinamou family. This genus comprises three species of this South American family.
