Grassland sparrow

The grassland sparrow is a robust species with a large head and a short tail, with a total length of about 13 cm (5 in). The wings are short and the legs fairly long.[2] The upper parts are brownish-grey streaked with black. The breast and flanks are greyish-buff or pinkish-buff and the underparts are dull white. There is a narrow white eye-ring, and a spot of yellow on the lores and another on the bend of the wing. The song is a high-pitched but thin series of plaintive phrases, "eee, telee, teeeee". This bird is similar in appearance to the yellow-browed sparrow, but that has more yellow on the face and the voice is quite distinct.[3]

This sparrow is native to the western half of South America. Its range includes Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela.[1] Its typical habitat is tall savannah grassland, but it also inhabits pastureland and cerrado. It is present in lowland areas and at altitudes of up to 1,100 m (3,600 ft), possibly higher in southern Venezuela.[3]

A "secretive" bird, this species feeds on the ground and flits away into the vegetation if disturbed.[3] It can be observed when singing from an elevated perch, and feeds out in the open in the early morning and late evening.[3] The diet consists of grass and other seeds, and small insects are also eaten, particularly during the breeding season. The nest is cup-shaped and built on the ground, with a runway through the foliage leading to it.[2]

The grassland sparrow is a common bird and has a very extensive range. No particular threats to this bird are known and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".[1]
