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.
For example, the male great-tailed grackle is 60% heavier than the female. The smallest icterid species is the orchard oriole , in which the female averages 15 cm in length (6 in) and 18 g (0.040 lb) in weight, while the largest is the Amazonian oropendola , the male of which measures 52 cm (20 in) and weighs about 550 g (1.21 lb).

This is shown in the red-winged blackbird by Pribil and Searcy (2001). Female red-winged blackbirds prefer to mate with males with territories over water and also unmated males. The females were given a choice between unmated males or previously mated males with the superior territories over water. In 12 out of 14 trials (86%) females chose the ...
The female bird primarily incubates for 12–14 days. [5] The chicks leave the nest only 2 weeks after hatching. [5] Nests are not built in isolation, but in colonies of up to 30 pairs. [5] Pairs prefer to nest in areas that are around 20–40' in treetops. However, colonies that live near water may also nest in reeds and other freshwater ...
