Range
In the central United States and Mexico, Cassin’s Sparrows may be found. During the winter, those living farther north in the range go a little ways south.
Habitat And Diet
Semi-arid regions, such as deserts and grasslands with yucca, mesquite, oak, and acacia trees and bushes, are home to Cassin’s Sparrows. While they seek appropriate perches on which to launch for flight and to perform their melodious singing, they choose lofty, thick grass for nesting and protection for their fledglings.
During the summer, Cassin’s Sparrows eat grasshoppers, caterpillars, and beetles. They prefer grass and weed seeds in the winter.
Nests
Cassin’s Sparrow nests are frequently found among tall grass. The tunnels, built of grass rootlets, flowers, and animal hair, are placed on the ground or at the rootlets of the cactus. A nest with three to five eggs will take about two weeks to hatch. Both parents are responsible for incubating the eggs.
Fun Fact:
Although the male Cassin’s Sparrows may appear to be uninspiring, they compensate with their “skylarking.” During the breeding season, they fly in the air and glide down to sing their song.
