![]() ![]() However, after emerging from their eggs, they begin to make “peep” noises, which eventually evolve into “Tutz-utz-utz”. Prior to or during hatching, there is no recorded information regarding their vocalization. A majority of females have brown irises, but a tiny percentage of females in Wisconsin have yellow irises. Their eyes are bright, contrasting shades of yellow in comparison to their dark or dull plumage.Īdult male Brewer’s Blackbirds have yellow, round irides, which can appear white under strong lighting. They often appear as small, healthy-size birds with a round head, a black bill, and short black legs. Adult females and year-old males also have the same iridescence, albeit slightly more difficult to spot. While it is mostly in adult males during the breeding season. One of the most identifiable features of Brewer’s Blackbirds is the purple and blue-green iridescence spotted on their heads. In an instance, around 40% of a flock of 500 Brewer’s Blackbirds have spots of white or white feathers. Female juveniles are identical to their male counterparts but are a lighter shade.Īlthough extremely rare, partial albinism has been spotted in this species. ![]() Their underparts are brownish-grey, closely resembling basic female Brewer’s Blackbirds, sans the iridescence and gloss. Male juvenile Brewer’s Blackbirds have dark and dull brown upper parts, including their wings. While adult males have bright yellow eyes, adult females have dark brown eyes. The males have the slightest hint of the same glossy colors.įirst-year males look similarly to adult females, with a brownish-black plumage and a weaker gloss. On the contrary, adult females have a brown and gray plumage. During the breeding season, adult males have black plumage, a glossy purple head, and a bluish-green gloss on the rest of their bodies. The color pattern of Brewer’s Blackbirds can vary depending on the sex and the breeding status of the species.

Owing to the ease at which they are studied, Brewer’s Blackbirds have often been used as a subject model to evaluate hypotheses concerning behavioral and evolutionary ecology. Over the span of 4 decades beginning from their first recorded discovery, the species expanded their nesting population rapidly and can now be commonly found in the south-eastern United States.
