Brewer's Blackbird

Scientific name: Euphagus cyanocephalus

Though Brewer’s Blackbirds were formerly only found in the central and western U.S., dramatic habitat changes due to forest clearing and agricultural changes in the early 1900s enabled their rapid expansion to the east. There are both migratory and non-migratory populations of Brewer’s Blackbirds in different regions of the country.

Studies have found that Brewer’s Blackbirds spend significantly more time foraging when the winter temperature is colder. This, together with the short winter days, means that they cannot winter as far north as other species that are better adapted to the cold.
