The red-winged blackbird (Agelaius phoeniceus) is a species of passerine bird of the family Icteridae, and found throughout the marshlands of much of North America.

Description

The red-winged Blackbird is 7-9 inches in length, and has a wingspan between 12-16 inches. The male is a glossy-black in color, and can be mistaken for a small crow but for the red epaulets on their wings. When at rest the red on the folded wing is partially concealed; in flight or in courtship displays with the wings partially-spread open, the red coloration covers nearly half of wing area above the secondaries. Yellow also stands out as a border on the rearward edge between the red and the black. Female birds have the look of a large sparrow; predominately brown in color, their plumage is tinged with dark streaks; instead of a red epaulet there is a patch of a richer brown. Young birds are colored in a pattern similar to adult females.

Its voice has been described as a musical "konk-la-ree" sound.[2]

Name

The Latin name for the bird is based on two specific characteristics about the bird itself. The first, Agelaius refers to the fact that these birds are often seen in large flocks; in fact, some studies have determined they have the largest overall number of any living North American bird. The species name, phoeniceus, refers to the deep red color on their wings.

In addition to English, various Native American tribes have also given them names which refer to the red color. The Ojibwa language ("memiskondinimaanganeshiinh"), the Odawa language ("memeskoniinisi" or "memiskonigwiigaans") of Ontario and Michigan, and the Lakota language ("wabloša") of the Great Plains specifically identify this bird by the red wing patch. Other tribes have taken a differing approach; the Oji-Cree language of northern Ontario and the Ojibwa language of northwestern Ontario and Manitoba call it a "jachakanoob" and a "jachakanoo" respectively, in essence identifying it as a type of junco.

Range

Red-winged blackbirds are found over much of North America, from from Alaska and northwestern Canada south to northern Central America, spanning the continent to both coasts. Migrations take place only with those birds which breed in northern areas, where they migrate to the southern U.S. between late August to October; other bird populations which breed in southern climates generally stay year-round.

Subspecies

Currently, 22 subspecies are recognized by various authorities; others recognize as much as 24. The subspecies A. p. richmondi and A. p. fortis have been recently proposed to be three[3] and four[4] distinct subspecies, respectively, as well.

Habitat

Red-winged blackbirds are open-country birds, living in fields and near forest edges, but it is wetlands which they prefer. They are most often seen near marshes, creeks, or any waterway adjacent to fields. Seeds, grains, and insects make a large part of their diet.
