Guide to North American Birds

One of the most brilliantly colored songbirds in the east, flaming orange and black, sharing the heraldic colors of the coat of arms of 17th-century Lord Baltimore. Widespread east of the Great Plains, Baltimore Orioles are often very common in open woods and groves in summer. Their bag-shaped hanging nests, artfully woven of plant fibers, are familiar sights in the shade trees in towns. This bird was formerly considered to belong to the same species as the western Bullock's Oriole, under the combined name of Northern Oriole.

Among our most familiar birds, Red-wings seem to sing their nasal songs in every marsh and wet field from coast to coast. They are notably bold, and several will often attack a larger bird, such as a hawk or crow, that flies over their nesting area. The red shoulder patches of the male, hidden under body feathers much of the time, are brilliantly displayed when he is singing. Outside the nesting season, Red-wings sometimes roost in huge concentrations.

Throughout the east and midwest, this big blackbird is a very familiar species on suburban lawns, striding about with deliberate steps as it searches for insects. Common Grackles often nest in small colonies, and several males may perch in adjacent treetops to sing their creaking, grating songs. Big flocks are often seen flying overhead in the evening, heading for major communal roosts, especially from late summer through winter.

Centuries ago this bird probably followed bison herds on the Great Plains, feeding on insects flushed from the grass by the grazers. Today it follows cattle, and occurs abundantly from coast to coast. Its spread has represented bad news for other songbirds: Cowbirds lay their eggs in nests of other birds. Heavy parasitism by cowbirds has pushed some species to the status of 'endangered' and has probably hurt populations of some others.

In the west, this oriole is common in summer in forest edge, farmyards, leafy suburbs, isolated groves, and streamside woods, especially in cottonwood trees. For several years it was considered to belong to the same species as the eastern Baltimore Oriole (with the two combined under the name Northern Oriole), because the two often interbreed where their ranges come in contact on the western Great Plains. The habits of the two are similar.

Fluttering over meadows and hayfields in summer, the male Bobolink delivers a bubbling, tinkling song which, loosely interpreted, gives the species its name. The male is unmistakable in spring finery, but before fall migration he molts into a striped brown appearance like that of the female. Bobolinks in this plumage were once known as 'ricebirds' in the South, where they occasionally used to cause serious damage in the ricefields.

The male Yellow-headed Blackbird is impressive to see, but not to hear: it may have the worst song of any North American bird, a hoarse, harsh scraping. Yellow-heads nest in noisy colonies in big cattail marshes of the west and midwest; when not nesting, they gather in flocks in open fields, often with other blackbirds. At some favored points in the southwest in winter, they may be seen in flocks of thousands.

Remarkably similar to the Eastern Meadowlark in colors and pattern, this bird is recognized by its very different song and callnotes. The two species of meadowlarks evidently can easily recognize their own kind the same way; even where their ranges overlap in the Midwest and Southwest, they almost never interbreed. However, the two species do seem to see each other as potential rivals, and they actively defend territories against each other.
