The Red winged Blackbird (Agelaius phoeniceus) is one of the most abundant and recognizable birds across North America. Glossy-black males have scarlet-and-yellow shoulder patches they can puff up or hide depending on how confident they feel. Females are a subdued, streaky brown, almost like a large, dark sparrow.
Habits and Behavior
These birds are commonly seen perched atop cattails, along soggy roadsides, and on telephone wires. Their early and tumbling song is a happy indication of the return of spring. Red-winged blackbirds are also known for their audacity. They often attack larger birds, such as hawks or crows, that venture into their nesting areas.
All About Birds
Diet
The diet of the Red-winged Blackbird is varied, including seeds, insects, and other small invertebrates. This diverse diet allows them to adapt to different habitats and seasons.
Reproduction
Males are polygynous, having up to 15 females nesting within their territory. However, studies have shown that many offspring are not sired by the territorial male. This indicates complex breeding behaviors within the species.
Red-Winged Blackbird Migration
Northern populations migrate south for the winter, while those in more temperate regions remain year-round. During the non-breeding season, they often form large flocks, sometimes in massive concentrations.

Florida Book Awards, Gold Medal for Visual Arts
In photographs that surprise with their eye-catching composition and amaze with their detail, The Art of Birds captures the beauty of birds as most people never see them. Jim Miller focuses his camera lens on distinctive and spectacular species found in the wetlands and along the shorelines of Florida and the southeast, portraying their behaviors in their natural habitats.
Similar Species
Several bird species exhibit similarities to the Red-winged Blackbird. For instance, the Tricolored Blackbird (Agelaius tricolor) closely resembles the Red-winged Blackbird. However, it can be distinguished by a white border below its red shoulder patch. This differs from the yellow border seen in Red-winged Blackbirds.

Vocalizations
The Red-winged Blackbird is renowned for its distinctive vocalizations, which play a crucial role in communication and territorial displays.
Male Song
The male’s primary song is a characteristic sound of wetlands across North America. This song, often described as “conk-la-ree!”, is a classic sound of wetlands across the continent. The 1-second song starts with an abrupt note that turns into a musical trill. Males often sing from a high perch. They lean forward, droop their wings, spread their tail feathers, and fluff their bright shoulder patches to show them off.
This vocalization serves multiple purposes:
- Territorial Claim: By singing, males assert ownership over a specific area, deterring rival males.
- Attracting Mates: The song also plays a role in attracting females during the breeding season.
Males often deliver this song from elevated perches. They use locations like cattails or shrubs. They display their vibrant shoulder patches to maximize visual impact.
Female Song
Females also vocalize, though their songs differ from those of males. A female’s song is a series of three to five short chit or check notes. These vocalizations typically respond to a singing male and serve functions related to mate communication and territoriality.

Calls
Beyond their songs, Red-winged Blackbirds employ various calls for communication:
- Check Call: A distinctive, matter-of-fact “check” sound used by both sexes throughout the year. This call is utilized during flight, feeding, and interactions with rivals.
- Alarm Call: A rapid, scolding “chak chak chak” emitted in response to potential threats, signaling alertness to nearby individuals.
These calls are integral to the species’ social interactions and survival strategies.
