Western Meadowlark: This short stocky, ground-dwelling bird has dark-streaked brown upperparts, bright yellow underparts, and a broad black V on the breast. It has a dark brown-and-white striped crown, sharply pointed bill and brown tail with white edges. Feeds mostly on insects but also eats seeds. Flies low, with rapid shallow stiff wing beats followed by short glides. Sexes are similar.
Range and Habitat
Western Meadowlark: Breeds from British Columbia, Manitoba, northern Michigan, and northwestern Ohio south to Missouri, central Texas, and northern Mexico; has spread eastward in recent years. Spends winters in much of its breeding range north to southern British Columbia, Utah, and Arkansas. Preferred habitats include meadows, plains, and prairies.
The largest taxonomic order of birds, the PASSERIFORMES (pronounced pas-ser-i-FOR-meez), is divided into one hundred eighteen families and encompasses over half the world's known bird species, including many familiar birds such as finches, swallows, thrushes and blackbirds.
The blackbird family, Icteridae (pronounced ik-TER-i-dee), includes one hundred and four species in twenty-seven genera found only in the New World.
There are fifty-seven species of blackbirds in thirteen genera that occur in North America; included in this family are the long-tailed grackles, brightly colored orioles, and the meadowlarks and bobolink of the grasslands.
Blackbirds such as the Red-winged Blackbird are known for their highly social flocking behavior while orioles are more known for their colorful plumage and woven hanging nests. In the case of the meadowlarks, it is their pleasant prairie songs that bring them recognition.
Most blackbirds and orioles are slender, long-tailed birds while the grassland loving meadowlarks, Bobolink and cowbirds have chunkier bodies and short tails. Despite these differences in body shape, all blackbirds share a sharp, straight bill that can be used to forage for both small creatures and grain. All blackbirds also have fairly long legs and strong feet.
Males of several blackbird species have mostly black plumage highlighted by iridescence or bits of bright color such as red markings in the wings or staring yellow eyes. Females lack such attention getting aspects to their plumage but make up for it with subtle browns and streaked patterns that camouflage them while sitting on their nests. Streaked, cryptic plumage also helps hide both sexes of meadowlarks while orioles stand out with striking orange, yellow and black plumages.
In the United States and Canada, blackbird species are primarily birds of non-forest or second growth habitats including wetlands and in the case of meadowlarks and the Bobolink, grasslands. The lone forest dependent species is the Rusty Blackbird; a bird of wooded swamps.
Most blackbirds are short distance migrants that leave the cold north for the milder winters of the southern states although the orioles and the Bobolink undertake long distance migrations to Central and South America.
Most blackbirds are very social in nature with some species taking this behavior to an extreme in southern fields and wetlands during the winter months. In such areas, wintering flocks of Red-winged Blackbirds and grackles can form conglomerations of tens of thousands of birds that fill the country air with their rusty calls and sound of rushing wings.
The Icteridae include some of the most abundant bird species in North America. Nevertheless, two species, the Rusty and Tricolored Blackbirds, are threatened or endangered because of loss of their wetland habitats. One species, the Slender-billed Grackle, is presently listed as extinct, also due to the loss of its wetland habitat.
The blackbird family includes the only brood parasites in North America; the cowbirds. Like the Old World Common Cuckoo, instead of building their own nests, cowbirds leave their eggs in the nests of other species; a behavior that has a negative impact on the host species' nestlings and has contributed to the decline in many songbird species populations. Many species of grackle are mimics, having the ability to reproduce some sounds they commonly hear around them; for those living in developed areas, car alarms are a frequently learned and reproduced sound.
