As a result of the shy, elusive nature of Le Conte’s sparrow, very little is known about its biology and behaviour (3). However, it is thought to nest in May and June. The nest consists of a small, open cup of fine grasses, lined with grass and hair, and is placed on or just about the ground (2) (3). Usually, 4 or 5 eggs are laid, and are incubated for around 13 days (3).
Le Conte’s sparrow usually forages on the ground and in low vegetation, where it feeds on a variety of seeds and arthropods. It is thought to maintain territories using calls, which may also be used to attract a mate during the breeding season (3).
