Henslow's sparrow is a North American passerine bird in the family Passerellidae. It was named by John James Audubon in honor of John Stevens Henslow. It was originally classified in the genus Emberiza and called Henslow's bunting.
Region
Eastern and Central North America
Typical Environment
Breeds in the northeastern and midwestern United States in tallgrass prairies, wet meadows, restored grasslands, and lightly grazed hayfields with dense litter. Prefers areas with standing dead vegetation and a deep thatch layer for nesting and cover. Winters mainly in the southeastern United States, frequenting weedy fields, marsh edges, pine savannas, and damp grasslands. Avoids heavily shrubbed or frequently mowed fields and is highly patch-dependent across its range.

Henslow's sparrow is a secretive grassland specialist with a distinctive, insect-like 'tsi-lick' song. It was named by John James Audubon in honor of botanist John Stevens Henslow. The species depends on dense, grassy habitats with deep thatch, making it sensitive to mowing and habitat fragmentation. Conservation programs that maintain tallgrass and wet meadows can significantly benefit its populations.
Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats in low, fluttering flights
Social Behavior
Typically nests on or near the ground in dense grass, often under an arching canopy of dead stems. Pairs are generally monogamous, and males sing from low perches or from within vegetation. Outside the breeding season, it may gather loosely in suitable fields but remains inconspicuous.
Migratory Pattern
Seasonal migrant
Song Description
Song is a brief, insect-like 'tsi-lick' or 'see-lik,' often delivered from concealed perches. Calls are thin and high, carrying surprisingly well over grasslands, and can be difficult to locate due to ventriloquial quality.
