Song Sparrows are ground foragers, although they will come to bird feeders. When snow and ice cover the ground, they eat seeds, grains (including corn), and dried fruit. During the summer, they add invertebrates and a wide array of fresh plant food to their diets.
Song Sparrows breed from early April through late July. Females use grasses, weeds, and bark to build cup-shaped nests, which they line with soft materials, including more grass, rootlets, and hair. They lay one to six brown-spotted pale eggs per clutch and produce up to four broods per year. Females incubate eggs for 12-15 days and young stay in the nest for 9-12 days before fledging. Females often initiate subsequent nest and incubation before young become independent of parental care. Males provide all care for existing broods when females start a new brood.
Although both Song Sparrows and House Sparrows are called ‘sparrows’, Song Sparrows belong to the Emberizidae, or American sparrows. To learn more, visit Cornell’s website.
