The russet sparrow ("Passer cinnamomeus") also called the cinnamon sparrow or cinnamon tree sparrow, is a bird that is part of the sparrow family. It is a small bird with a thick beak, and is 14 to 15 centimetres long. Its feathers are mainly rufous (reddish-brown) above and grey below, and its sounds are made up of short chirps which it can sometimes join together to make a song. There are 3 subspecies of the Russet Sparrow, "rutilans" (the main species), "intensior", which, along with the main species, lives in parts of eastern Asia, and "cinnamomeus", which lives in the Himalayas and is commonly seen around terrace farms. The Russet Sparrow mainly eats seeds from herbs and grains, and it is the common sparrow of towns and cities that Eurasian Tree Sparrows and House Sparrows do not live in.
