- Cool Facts
- The Henslow's Sparrow sings most actively at dawn and dusk, but sometimes sings all night long.
- The Henslow's Sparrow takes flight only with great reluctance, preferring to flee from threats by running through the grass.
- Henslow's Sparrow was named by John James Audubon in honor of John Stevens Henslow, a botanist, minister, good friend of Audubon, and teacher of Charles Darwin.
- Originally the distribution of Henslow's Sparrow was concentrated in two areas: the central prairies of the United States and the coastal marshes of the Atlantic Coast. As the forests in the intervening states were cut down, the Henslow's Sparrow moved into the newly created grasslands, connecting the two centers of distribution. It has largely disappeared from coastal marshes.
- The oldest recorded Henslow's Sparrow was at least 6 years, 6 months old when it was recaptured and rereleased during banding operations in Louisiana in 2001.
