The spotted nothura (Nothura maculosa) is a species of tinamou. This bird is native to grassy habitats in eastern and southern Brazil, Paraguay, Uruguay, and eastern and northern Argentina. [3]
The spotted nothura is approximately 24 to 25.5 cm (9.4–10.0 in) in length. [4] The upper parts are brown with streaked buff. The under parts are buff streaked with black and brown on the breast, with barring to the flanks. Its crown is black streaked with buff and the throat is white. The overall hue in colour varies greatly over its range; in part caused by the differences in soil at the specific localities. It and the closely related Chaco nothura, N. chacoensis, are the only nothuras with barring to both webs of the primaries. The legs are dull yellowish-grey or brown.
The call of the spotted nothura is a series of brief high-pitched notes. [4]
The spotted nothura eats plants, typically seeds, and animal matter. In Argentina they seem to eat more of the animal matter then they do in other locations. [4]
This species can reproduce rapidly, as the female is mature within 2 months and can have five to six broods per year. The male does not mature as fast. The male will incubate the eggs and raise the chicks. [4] Like most tinamous, its eggs have a spectacular glossy porcelain-like shell. This is colored a rich maroon or chocolate brown in this species. The clutch contains 4-6 eggs.
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. [4]
Coenraad Jacob Temminck first identified the spotted nothura from a specimen from Paraguay, in 1815. [4]
The spotted nothura has nine currently recognized subspecies. They are not well-distinguished and almost form a cline that varies north to south according to Gloger's and Bergmann's Rules.
It occurs in eastern and southern Brazil (excluding the Mata Atlântica and planalto uplands along the coast), Paraguay, Uruguay, and Argentina. [3]
It lives in dry savanna habitat up to 2,300 m (7,500 ft), and temperate grassland, as well as pasture land. [4] [7] [8]
The IUCN list this tinamou as Least Concern, [1] even though it is avidly hunted, due to its fast reproduction rate. [4] It has an occurrence range of 3,900,000 km2 (1,500,000 sq mi). [8]
Tinamous form an order of birds, comprising a single family with 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 have traditionally been regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation, implying basal ratites could fly. 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.
