what is the size of a red tailed hawk
Red-tailed hawk The red-tailed hawk (Buteo jamaicensis) is a bird of prey, one of three species colloquially known in the United States as the "chickenhawk," though it rarely preys on standard-sized chickens.[2] It breeds throughout most of North America, from western Alaska and northern Canada to as far south as Panama and the West Indies, and is one of the most common buteos in North America. Red-tailed hawks can acclimate to all the biomes within their range. The 14 recognized subspecies vary in appearance and range. It is one of the largest members of the genus Buteo in North America, typically weighing from 690 to 1,600 g (1.5 to 3.5 lb) and measuring 45–65 cm (18–26 in) in length, with a wingspan from 110–145 cm (43–57 in). The red-tailed hawk displays sexual dimorphism in size, with females averaging about 25% heavier than males.[3] The bird is sometimes referred to as the red-tail for short, when the meaning is clear in context.
Red-winged blackbird The red-winged blackbird (Agelaius phoeniceus) is a passerine bird of the family Icteridae found in most of North America and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the southern United States. Claims have been made that it is the most abundant living land bird in North America, as bird-counting censuses of wintering red-winged blackbirds sometimes show that loose flocks can number in excess of a million birds per flock and the full number of breeding pairs across North and Central America may exceed 250 million in peak years. It also ranks among the best-studied wild bird species in the world.[2][3][4][5][6] The red-winged blackbird is sexually dimorphic; the male is all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Seeds and insects make up the bulk of the red-winged blackbird's diet.
