Harris’s Sparrow
At a Glance
This big, elegant sparrow is a bird of the heartland, nesting in north-central Canada, wintering mainly on the southern Great Plains. Because of its remote habitat and shy behavior in summer, its nest was not discovered until 1931, long after those of most North American birds. Harris's Sparrow is more easily observed in winter on the southern plains. Flocks feed on the ground near brushy places, flying up when disturbed to perch in the tops of thickets, giving sharp callnotes.

Behavior
Eggs
3-5, usually 4. Pale green, marked with brown. Incubation is by female only, 12-15 days.
Young
Both parents feed the nestlings. Young leave nest about 8-10 days after hatching, unable to fly until a few days later. 1 brood per year.
Feeding Behavior
Forages mostly while hopping on ground, sometimes scratching in leaf-litter with feet. Also does some foraging up in bushes.
Diet
Mostly seeds, insects, berries. Diet varies with season, may include more seeds in winter, berries in late spring after arrival on breeding grounds, insects during summer nesting season. Items important at some seasons include seeds of weeds and grasses, fruits of crowberry and bearberry, and various beetles, flies, caterpillars, true bugs, and other insects, as well as spiders. Also eats some flowers and conifer needles.
Nesting
Male defends nesting territory by singing and by actively chasing intruding males. Pairs form quickly after arrival on breeding grounds, soon after territories established. Nest site is on ground, usually on small hummock, well hidden under dwarf birch, alder, spruce, or other shrub or low tree. Typically in shallow depression scraped out in moss or other ground cover, sometimes placed under overhang of rock or soil. Nest (probably built by female) is a cup of moss, lichens, twigs, lined with fine grass and sometimes animal hair.
Climate Vulnerability
Conservation Status
Common within its range, numbers apparently stable. Breeding range is mostly remote from effects of human activity.
