This bird, believed to be the second kind of ibis spoken of by Herodotus, is rather smaller than the sacred ibis, and mostly of a dark chestnut colour with brilliant green and purple reflections on the upper parts, exhibiting, however, when young none of the rufous hue.
The plumage is generally inconspicuous: some tint of brown, ranging from rufous to slaty, and often more or less closely barred with a darker shade or black, is the usual style of coloration; but some species are characterized by a white throat or a bay breast.
In Burma the species is represented by the tsaine, or h'saine, in which the colour of the adult bulls is rufous fawn.
The groundcolour of the fur varies from a pale fawn to a rufous buff, graduating in the Indian race into pure white on the under-parts and inside of the limbs.

The groundcolour of the upper and outer parts of the head, body, limbs and tail is bright rufous fawn; and these parts are beautifully marked with transverse stripes of a dark, almost black colour.
Its plumage is plain in colour, being of an almost uniform greyish black above, the space round the eyes and a ring round the neck being variegated with white, and a patch of pale rufous appearing above the carpal joint, while the lower parts of the body are white.
This relatively small cat, uniformly coloured, is generally of some shade of brownish-grey, but in some individuals the fur has a rufous coat, while in others grey predominates.
In the red coati, ranging from Surinam to Paraguay, the tail is marked with from seven to nine broad fulvous or rufous rings, alternating with black ones, and tipped with black.
To the ordinary spectator Tinamous have much the look of partridges, but the more attentive observer will notice that their Rufous Tinamou (Rhynchotus rufescens).
