A Male Chipping Sparrow sings while sitting high in a black walnut tree
Chipping Sparrows are normally found either on the ground or in low brush. During their mating season, males such as this one, perch high above the ground to sing their mating songs.
While gathering information on the Chipping Sparrows, I found that they commonly line their nest with hair. They will use any type of hair they can find and have even been observed picking strands of hair from sleeping dogs.
