Red-winged Blackbird (Agelaius phoeniceus)
Red-winged Blackbirds are common throughout America and can be found in cattail marshes. Males are glossy black with red and yellow shoulder patches which they puff up or hide depending on how confident they feel. Females are more subdued in a streaky brown coloration. This species of bird is highly polygynous, males tend to have many females nesting on their territory. However, one-quarter to half of nestlings turn out to be sired by a male other than the territorial male.
