Guide to Boreal Birds
The Chipping Sparrow's habit of lining its nest with hair has earned it the name "Hairbird." Formerly, it utilized horsehair, but with the decline in the use of horses it takes any hair available and will even pluck strands from the coat of a sleeping dog. Originally inhabitants of natural clearings and brushy forest borders, these sparrows are now found in gardens and suburban areas and have become familiar songbirds. During most of the year they feed on the ground, but in the breeding season males always sing from an elevated perch. Their food consists mainly of seeds, but in summer the adults and the young feed on insects.
