The Le Conte’s sparrow (''Ammodramus leconteii'') is one of the smallest sparrow species in North America.〔Terres, J.K. (1980). The Audubon Society Encyclopedia of North American Birds. New York: Alfred A. Knopf〕 It is a very secretive bird that prefers to spend most of its time on the ground under the cover of tall grasses.〔 They are typically very difficult to flush, often only flushing at a distance of 1–3 m as they prefer to run across the ground.〔Le Conte's sparrow. (n.d.). Retrieved September 2011, from Cornell Lab of Ornithology: http://www.allaboutbirds.org/guide/Le_Contes_sparrow/lifehistory〕 When they do emerge they rarely fly more than a foot or two above the grass and often descend again within a few meters.〔〔Vanner, M. (2004). ''The Encyclopedia of North American Birds''. Bath: Parragon Publishing.〕 Because it is so rarely seen, there are still many gaps in knowledge about the Le Conte’s sparrow. Nests are often very hard to find, and individuals are more often identified by sound than by sight. ==Description== The Le Conte’s sparrow is a small sparrow with a relatively large head, short grey bill and short pointed tail. It has a buffy yellow-orange face with grey cheeks, and a dark brown crown with a white central stripe. The nape of the neck is lilac grey with chestnut streaks, and the back is streaked with brown and beige. Its belly is off white, while the breast and sides are a buffy orange-yellow with dark brown streaks. The feet and legs are a brownish-pink colour.
