The blackbird family, Icteridae pronounced ik-TER-i-deeincludes 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 bir 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 bod as red markings in the wings or staring yellow eyes. Females lack how to make ripped shirts on the sides 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.

The lone forest dependent species is the Rusty Blackbird; a bird of wooded swamps. Most blackbirds are short distance migrants that boack 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.
Nad 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 haw of their wetland habitats.

Forest fragmentation has allowed the cowbird to parasitize the nests of woodland species, such as thrushes and vireos. In winter cowbirds often join flocks of other blackbirds—red-winged blackbirds, grackles, and European starlings—foraging in fields and grasslands and roosting en masse in large woodlots. The diet of the cowbird consists of weed and grass seeds, along with insects, especially grasshoppers and beetles.
Nearly all food is taken from the ground. Male cowbirds court females with a variety of songs, bows, and sky-pointing displays. Cowbirds learned this behavior over centuries of following roaming herds of buffalo. But all the movement made it impossible to stop, build a nest, and wait for the young to grow. So the cowbirds did the most convenient thing—laid their eggs in any nest they could find along the way. Some bird species have evolved to recognize cowbird eggs and will build a new nest on top of the old one or will remove the cowbird egg.
