Henslow's Sparrow is a small, exceedingly secretive grassland bird known for its flat-headed appearance, olive-green wash on the head and neck, and weak, insect-like song. It is a critically endangered species.
Where to spot
Breeds in scattered populations in the eastern and central United States. Winters in the southeastern United States. Inhabits tall-grass prairies, old fields, and open pine savannas with dense ground cover.
How to spot
Finding this bird typically requires searching specific, protected grassland habitats and listening intently for its almost inaudible song, often described as a faint 'tsilick' or 'fiz-ick'. Visually, look for its large, flat head, short bill, and olive wash on the neck.
When to spot
Breeds in summer (May-July). Migrates south in autumn (Sept-Nov) and north in spring (Mar-May). Most active and vocal during the breeding season, especially at dawn and dusk.

This sparrow is considered one of North America's most elusive birds; its subtle song and preference for remaining hidden in dense grass make it incredibly difficult to find.
