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. 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. 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.Alsop, F.J. (2002). Birds of Canada. Toronto: Dorling Kindersley Handbooks

Behaviour

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 as they prefer to run across the ground. 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 LeConte's sparrow. Nests are often very hard to find, and individuals are more often identified by sound than by sight. For example, one survey of LeConte's sparrows identified 86 males by sound, but only 8 of those males by sight. For the same reason, very few LeConte's have ever been banded. Between 1967 and 1984, only 355 were actually banded, and none were ever re-captured.
