White-Crowned Sparrow

White-crowned Sparrow- Spec. Name: Zonotrichia Leucophrys

White-crowned Sparrow
White-crowned Sparrows appear each winter over much of North America to grace our gardens and favorite trails (they live in parts of the West year-round). The smart black-and-white head, pale beak, and crisp gray breast combine for a dashing look – and make it one of the surest sparrow identifications in North America. Watch for flocks of these sparrows scurrying through brushy borders and overgrown fields, or coax them into the open with backyard feeders. As spring approaches, listen out for this bird’s thin, sweet whistle.

  • Size & Shape
    The White-crowned Sparrow is a large sparrow with a small bill and a long tail. The head can look distinctly peaked or smooth and flat, depending on the bird’s attitude.
  • Color Pattern
    First impressions of White-crowned Sparrows tend to be of a plain, pale-gray bird; next your eye is drawn to the very bold black-and-white stripes on the head and the pale pink or yellow bill. Learn this bird's size and shape so you're ready to identify young birds that have brown, not black, markings on the head.
  • Behavior
    You’ll see White-crowned Sparrows low at the edges of brushy habitat, hopping on the ground or on branches usually below waist level. They’re also found in open ground (particularly on their breeding grounds) but typically with the safety of shrubs or trees nearby.
  • 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).

    Rock Pigeon

    Rock Pigeon - Spec. Name: Columba Livia

    Rock Pigeon
    A common sight in cities around the world, Rock Pigeons crowd streets and public squares, living on discarded food and offerings of birdseed. In addition to the typical blue-gray bird with two dark wingbars, you'll often see flocks with plain, spotted, pale, or rusty-red birds in them. Introduced to North America from Europe in the early 1600s, city pigeons nest on buildings and window ledges. In the countryside they also nest on barns and grain towers, under bridges, and on natural cliffs.

    • Size & Shape: Larger and plumper than a Mourning Dove, Rock Pigeons are tubby birds with small heads and short legs. Their wings are broad but pointed wings and the tail is wide and rounded.
    • Color Pattern: Variable in color, but most birds are bluish gray with two black bands on the wing and a black tip to the tail. Most birds have iridescent throat feathers. Wing patterns may include two bars, dark spots, or can be plain. The tail is usually dark tipped.
    • Behavior: Pigeons often gather in flocks, walking or running on the ground and pecking for food. When alarmed, the flock may suddenly fly into the air and circle several times before coming down again.
    • Habitat: Pigeons are familiar birds of cities and towns. You'll also see them around farmland and fields, as well as in their archetypal habitat, rocky cliffs.
