This swift is normally found only east of the great plains. Small birds at about 5 inches long, they are aloft all day long, and almost always in groups. They migrate in large flocks and nest from Canada to the Gulf of Mexico. Watching a flock of swifts flow funnel-like into a chimney is a startling evening experience. The birds express themselves with a chatter of chipping cries, one of the easiest identifications of the species. Their only food is insects, and they are highly beneficial.
This slim bird is only about 5 inches long. You can spot it by a chestnut brown crown, black line through the eye, and a black bill. Chippies nest throughout the United States; they even breed as far south as Nicaragua and as far north as southern Canada, and winter in the southern United States and Mexico.
Chipping sparrows are domestic birds that show little fear of humans. They often build nests in gardens, cemeteries or golf courses, where mowed lawns provide feeding areas. Among the most insectivorous of all sparrows, their diet consists mainly of insects, supplemented by weed seeds.
Adjectives are dangerous in describing wildlife, but chippies are just plain lovable.
Cowbirds are the only native American birds to always lay their eggs in nests of other species, and have the young raised by foster parents. Warblers, finches, and sparrows, all smaller than cowbirds, are the chief victims of this practice, the fast growing foster chick monopolizing food and space to the detriment of the legitimate offspring.
This is the smallest blackbird, flocking in small groups, or mixing with grackles and red-wings. They are usually quiet, their only song a faint whistle. They range north into Canada and winter in the southeastern States. Grasshoppers, beetles, and a number of insects are eaten, and like other blackbirds, they do some damage to grain.
Smart enough to adapt quickly to urban life, crows nest in such unlikely places as alongside the Pentagon, and feed in the White House grounds in Washington.
Typically, they feed in the early hours before many people are out, retreating to parks or fields when disturbed. Their nest-robbing, crop destroying habits are often exaggerated, and less attention paid to their diet of grubs, beetles, mice, and other pests.
