Red-winged Blackbird

Agelaius phoeniceus

The Red-winged Blackbird (Agelaius phoeniceus) is a striking and abundant passerine bird, belonging to the family Icteridae. Exhibiting pronounced sexual dimorphism, the male is resplendent with glossy black plumage, accented by a vibrant red shoulder patch edged with a yellow border. The female, in contrast, is cloaked in more subdued hues of brown, adeptly blending into her surroundings.

Identification Tips

Males are easily identified by their jet-black feathers and the scarlet and yellow "epaulets" on their wings. Females are more cryptic, with a mottled brown appearance, often with streaks or lighter undersides. Both sexes possess a pointed bill and a medium-length, rounded tail.


Red-winged Blackbirds are versatile in their choice of habitat, though they show a strong affinity for wetlands. They are commonly found in freshwater and saltwater marshes, particularly where cattails are present. They also inhabit dry upland areas such as meadows and prairies.


This species is widespread across North America, from Alaska and Newfoundland, extending south to Florida, the Gulf of Mexico, Mexico, and parts of Central America. They are also found in isolated regions of El Salvador, Honduras, and Costa Rica.


Red-winged Blackbirds are known for their territorial nature, especially during the breeding season. Males can be seen perched conspicuously, singing and displaying their shoulder patches, while females are more secretive, often foraging within dense vegetation.

Song & Calls

The male's song is a distinctive, scratchy "oak-a-lee," while the female's vocalizations include a chattering "chit chit cheer teer teer." Their calls serve as important communication signals within their social structure.


Nesting in loose colonies, the female constructs a basket-like nest attached to marsh vegetation or shrubs. Clutches typically consist of three to four eggs, which are incubated solely by the female. Red-winged Blackbirds are polygynous, with males defending territories that may contain multiple females.

Similar Species

The Tricolored Blackbird (Agelaius tricolor) can be confused with the Red-winged Blackbird, but males of the former have darker red epaulets edged with white, not yellow.

Diet and Feeding

An omnivorous bird, the Red-winged Blackbird's diet includes seeds, grains, insects, and small animals. They exhibit foraging flexibility, adapting their diet seasonally and based on availability.

Conservation Status

The Red-winged Blackbird is classified as Least Concern by the IUCN. Despite its abundance, habitat destruction and changes in agricultural practices have led to population declines in some areas. However, the species' adaptability has allowed it to persist in a variety of environments.

What Our Birders Say
Loving it
I really enjoy being able to interact with other birders on this platform! This seems like a great way to meet other birders and find some new spots.
Great app for beginner twitchers
I’ve had a passion of photographing birds for a long time now but have only just gotten into proper birdwatching, and this app is brilliant for those just getting started. There is a great sense of community among users and the app is very easy to use and professional. Awesome app altogether

App got me interested in birding!
Super friendly community <3 This app got me interested in birding! It teaches me cool stuff and its super friendly, and fun :) The species guide is really developing my knowledge, and i love seeing cool new birds from round the world!
Just what birding needs
We need more fun in birding, for years it has had a reputation for being up tight and stuffy and only perused by retirees and anoraks. Birda helps change that perception and firmly brings birding into the 21st century! Fun, interactive while still contributing to science and conservation. If you aren’t on it, why not??

Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.
