Information about the Bird Dwarf Tinamou
The dwarf tinamou (Taoniscus nanus) also known as the least tinamou, is a small, superficially partridge-like bird with short tail and wings.
It is approximately 16cm (6.3in) long. It is greyish-brown with a pale throat, boldly patterned neck and upper parts, and it has brown-barred buff underparts and a blackish crown. Some individuals are significantly darker and greyer than others, but it remains unclear if these plumage variations are morphs or differences between the sexes. The iris and legs are dull yellowish. It resembles a small dumpy nothura, but is more easily confused with the ocellated crake.
Its voice consists of high-pitched cricket-like trills followed by peet notes.
All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds. The dwarf tinamou is the only member of the genus Taoniscus and is a monotypic species.
The dwarf tinamou is found in the arid scrub grasslands, around 1,000m (3,300ft) in elevation, restricted to the Cerrado region of interior southeastern Brazil in Distrito Federal, Gois, Minas Gerais, Mato Grosso do Sul, So Paulo and formerly Paran. Specimens were also known from Paraguay (Misiones) and Argentina (the Ro Bermejo in either Chaco or Formosa), but all recent records are from Brazil. It is, however, highly inconspicuous and easily overlooked.
The diet of the dwarf tinamou consists mainly of grass seeds, termites, insects and arthropods.
The dwarf tinamou is currently threatened by the ongoing habitat loss caused by mechanised agriculture, intensive cattle-ranching, afforestation, invasive grasses, excessive use of pesticides and annual burning. It is also hunted by people for food in some areas. Farming and ranching are its largest threats. The dwarf tinamou is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It has an occurrence range of 57,700km2 (22,300sqmi), and the last population estimate, done in 2000, showed between 5,800 and 6,960 adults.
The dwarf tinamou is currently being conserved in three protected areas: Serra da Canastra National Park, Itapetininga Experimental Station and the IBGE Roncador Biological Reserve. Several areas adjacent to the Ro Bermejo, Argentina, have been surveyed with the aid of tape-playback, but the species has not been found. It was also been proposed to survey Serra do Cip National Park, Chapada dos Veadeiros National Park and Emas National Park specifically for this species with the aid of tape-playback. And conduct further surveys in Argentina and Paraguay in the areas where the specimen was collected. It was also been proposed to determine best management practices for existing protected areas and control the burning of cerrado habitats.
