Tinamotis

The Tinamous are one of the most ancient groups of bird, members of a South American bird family of about 47 species in 9 genera. Although they look similar to other ground-dwelling birds like quail and grouse, they have no close relatives and are classified as a single family Tinamidae within their own order, the Tinamiformes.


Of ultimately Gondwanan origin, they are distantly related to the ratites, the order Struthioniiformes that includes the Rhea, Emu, and Kiwi. Although the fossil record in South America is generally poor (or perhaps largely undiscovered as yet), the known tinamou fossil record goes back 10 million years.


Together with the ratites, they make up the Paleognathae, or “Old Jaws”, as distinct from the vast majority of modern birds in the Neognathae , or “New Jaws”.


There are 47 species of tinamou in South America and north to Mexico, occurring in a wide range of habitats. They eat a variety of food including insects and berries.


Tinamou are rarely seen. Most inhabit the tropical lowlands of South America, typically in dark, dense forest, but some species range as far north as Mexico and occur in a wide range of habitats. They eat a variety of food including insects and berries.


Although some species are quite common, they are very secretive. A small number of species live in more open, grassy country, but even these are wary. Tinamous lay several eggs which are attractively coloured and have a hard gloss like porcelain. The young are precocial, and can run almost as soon as they hatch.

Tinamiformes - Hutchinson encyclopedia article about Tinamiformes (152 words)
Fowl-like bird of the family Tinamidae, in the South American order Tinamiformes, of which there are some 45 species.
They are up to 40 cm/16 in long, and their drab colour provides good camouflage.

Dr. Siwo de Kloet (1682 words)
Tinamous (Aves, Palaeognathae, Tinamiformes) are primitive birds, generally considered to be the sister group to the ratites.
This paper describes experiments which show that the sequences of these forms are more similar to each other and to the homologous undifferentiated spindlin gene sequences in the ratite genome than to the W or Z forms of the spindlin gene in other, neognathous species.
This suggests that cessation of recombination at the spindlin locus of the ancestral W and Z chromosomes of the tinamiformes and the neagnathous avian species were independent events.
