White-crowned Sparrow – Zonotrichia leucophrys

General: I set a feeder up in front of a window in a garden close to the house and was surprised to see a flock of White-crowned Sparrows scurrying through the brushy borders. After research I found that their presence would be short lived since they were migrating north into Canada. After doing research I found this is a flocking bird and seeing a flock is common.(2) This is a stunning bird with really distinct markings.

White-crowned Sparrows will share their territories with Fox Sparrows, but chase Chipping Sparrows and Dark-eyed Juncos until they leave. (1)

White-Crowned Sparrows migrate across northern Canada and the western United States where it breeds. They nest either low in bushes or on the ground under shrubs. Females build nests out of twigs, coarse grasses, pine needles, moss, bark, and dead leaves. The female lays 3–7 pale green eggs spotted with brown. Incubation is 10 – 14 days. The chicks are born with sparse down feathers with closed eyes. They fledge in 8 – 10 days.

Identification: The White-crowned Sparrow is a large sparrow with a small bill and a long tail. White-Crowned Sparrows are approximately 5.9”–6.3” long and have a wingspan of about 8”-9.5”. They weigh between .8 – 1 oz. The head can look distinctly peaked or smooth and flat, depending on the bird’s attitude. The White-Crowned Sparrow has a black-and-white head, pale beak (pink or yellow), and crisp gray breast. The wings are brown with bars and the under-parts are grey. They are similar in appearance to the White-throated Sparrow but do not have the white throat markings or yellow marking on head.

Habitat: Look for White-crowned Sparrows in places where safe tangles of brush mix with open or grassy ground for foraging. For much of the United States, White-crowned Sparrows are most likely in winter (although two races live year round in the West, along the coast and in the mountains). (1)

Territory: Depending on time of year (see migration below) they are residents or transients in much of the US and Canada.

Migration: White-Crowned Sparrows migrate north to Alaska and northern Canada – from Manitoba to Newfoundland and into the western US mountain Areas (Washington and Oregon) in the spring. Their southern migration in the fall is to Southern US from Gulf States through to California north to New Jersey. They are year round residents in New Mexico and Arizona.

Food: The majority of foods White-crowned Sparrows eat are seeds, grains, fruit and insects such as caterpillars, beetles and other insects. (2)
