Habitat And Diet
You can find Henslow’s Sparrows in wet, weedy, and dense grasslands. However, their natural habitat is slowly disappearing, and they are now making their way towards abandoned farm fields, pastures, and anywhere they can find dense, tall grasslands.
Henslow’s Sparrows are highly secretive birds preferring to stay low and forage at the bottom of grass stalks. They eat seeds like sedges, ragweed, and smartweed. They also eat insects in the summer, such as grasshoppers and caterpillars. They’ve been known to eat berries, too.
Henslow’s Sparrow Call/Song:
Nests of Henslow’s Sparrows are made from grass and wildflowers placed in slight hollows or at the base of dense clumps of grass. The female lays three to five eggs, which she incubates for eleven days. It takes ten days for the young to fledge, and they are still cared for by their parents for a short period even after they leave the nest.
Henslow’s Sparrows prefer to run through dense grass rather than fly from danger.
