Le Conte's Sparrow

The Le Conte's Sparrow is a strikingly patterned but famously secretive little sparrow of wet, grassy prairie habitats. Despite bold, colorful markings, it is a master at staying hidden, preferring to run mouse-like through dense grass rather than fly into the open.

Adults show a bright orange-buff face and breast, a contrasting gray ear patch, and a purplish-chestnut streaked nape. The crown is dark with a pale, often whitish, central stripe, and the flanks show fine dark streaking against the warm buffy background. The overall effect is one of the most colorful and intricately patterned of the small grassland sparrows.

Because it stays so low and moves so quickly through cover, most observers get only brief glimpses, and the species is frequently detected first by its very high, thin, insect-like song.

Key Field Marks

• Bright orange-buff face and breast
• Contrasting gray patch on the ear coverts (cheek)
• Purplish-chestnut streaked nape
• Pale central crown stripe on an otherwise dark crown
• Fine dark streaking on the flanks

Similar Species

• Nelson's Sparrow: also has an orange face but shows blurrier, less crisp streaking and a plainer gray nape without the same purplish-chestnut tone
• Grasshopper Sparrow: shares an open grassland habitat but lacks the bright orange face and has a plain, unstreaked buffy breast

Behavior is a helpful clue: Le Conte's Sparrow tends to run through grass like a mouse rather than perch in the open, and it often flies only short distances low over the grass before dropping back down.

Le Conte's Sparrow breeds in wet meadows, sedge marshes, and moist, grassy prairie across the northern Great Plains of the United States and much of central Canada, favoring areas with a mix of standing dead grass (litter) and green growth.

In winter, the species moves to coastal marshes, weedy fields, and grasslands of the southeastern United States, particularly along the Gulf Coast, where it again favors dense, grassy cover close to the ground.

Behavior

This is one of the most secretive sparrows in North America, typically running through dense grass rather than flying, and reluctant to flush even when closely approached; when it does fly, flights are usually short and low before it drops back into cover.

Voice

The song is a very high, thin, buzzy insect-like sound, often rendered as 'tik-zzzzzz-tik,' easy to miss or mistake for an insect if not listening carefully.

Feeding

Diet includes small insects and seeds gleaned from the ground and low grass stems.

Nesting and Breeding

The nest is a well-hidden cup built low in dense grass or sedge, sometimes slightly domed. Clutches typically contain 3-5 pale eggs with fine speckling.
