About Ammodramus humeralis (Bosc, 1792)
The grassland sparrow (Ammodramus humeralis) is a robust bird with a large head, short tail, short wings, and fairly long legs. It reaches a total length of about 13 cm (5 in). Its upperparts are brownish-grey marked with black streaks; the breast and flanks are greyish-buff or pinkish-buff, and its underparts are dull white. It has a narrow white eye-ring, a yellow spot on the lores, and another yellow spot on the bend of the wing. Its song is a high-pitched, thin series of plaintive phrases transcribed as "eee, telee, teeeee". This species looks similar to the yellow-browed sparrow, but the yellow-browed sparrow has more yellow on its face and a completely distinct voice. This sparrow is native to the western half of South America, and its range covers Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela. Its typical habitat is tall savannah grassland, and it also lives in pastureland and cerrado. It occurs in lowland areas and at altitudes up to 1,100 m (3,600 ft), and it may be found at higher elevations in southern Venezuela.
