Henslow’s Sparrows are tan and buff marked with sharp black streaks. They have a distinctly greenish-olive wash on the cheek, with a yellow spot between eye and bill. The breast has neat black streaks and the belly is whitish.
Henslow’s Sparrows are extremely secretive, spending much of their time foraging at the bases of grass stalks in dense weedy fields. They prefer to run or walk rather than fly, and when flushed their escape flights are short and erratic.
