LeConte's sparrow is commonly mistaken for other small sparrows, such as the Nelson's sparrow (Ammospiza nelsoni), grasshopper sparrow (Ammodramus savannarum), Henslow's sparrow (Centronyx henslowii), saltmarsh sparrow (Ammospiza caudacuta), and Baird's sparrow. (C. bairdii).[4][5]
Taxonomy

LeConte's sparrow was first described by John Latham in 1790 but only received a valid binomial name from John James Audubon in 1844. He wrote, "I have named this interesting species after my young friend Doctor Le Conte, son of Major Le Conte, so well known among naturalists, and who is, like his father, much attached to the study of natural history."[7] It is generally believed that he meant John Lawrence LeConte (whose father had been an Army surveyor with the rank of major), although some feel that he was referring to another John LeConte, also a doctor, and John Lawrence's cousin.[citation needed]
Habitat and distribution
Range
LeConte's sparrow breeds in select areas of Canada, such as northeastern British Columbia, across Alberta, Saskatchewan and southern Manitoba as well as central Ontario and into Quebec; and as far south as northern Michigan, Montana and Minnesota. It winters in the southeastern United States; as far west as central Texas and as far north as central Illinois and Missouri.[8]
Habitat
LeConte's sparrow prefers moist open grassy areas with sufficient vegetation cover to provide shelter. Known habitat use includes meadows, fields, crop stubble, shallow marshy edges, prairie, and occasionally fens and lake-shores within the boreal forest.[8] Studies have shown that vegetation seems to have a greater impact on the abundance of this bird than other factors like climate or patch size.[9] Winter et al. (2005) says that it can be found at highest densities in areas with a "moderate amounts of bare ground". Agriculture and drainage of these areas is currently the greatest threat to LeConte's sparrow.[10]
Behaviour
It is a very secretive bird that prefers to spend most of its time on the ground under the cover of tall grasses.
Vocalizations
The male's song resembles a grasshopper buzz with a short squeaky introductory note and ending with a short chirp.[8] It is often described as tika-zzzzzzzzzzzz-tik while the call is a short tsip.[5][10] It is most commonly confused with the song of the Nelson's sparrow. The male generally sings from a concealed location, but can also be seen singing from the top of protruding grass stems, or occasionally in flight.[2]

Eggs
Eggs are 18 X 14 mm long and are sub elliptical in shape.[12] Eggs are white with undertones of green, grey or blue; covered in fine brown dots, speckles or splotches usually clustered near large end of egg.[12]
