Distribution

Red-winged Blackbirds are found across North America, from Alaska to Florida. They inhabit various open habitats, with a strong preference for wetlands, marshes, and wet meadows.

In winter, many northern populations migrate to the southern United States and Mexico, while some birds in milder areas remain year-round. They are common in suitable habitats throughout the USA and southern Canada.

Diet

Red-winged Blackbirds are omnivorous, with a diet that varies seasonally. During the breeding season, they consume insects, spiders, and other small invertebrates.

In fall and winter, they switch primarily to seeds, including those from grasses, weeds, and waste grain in agricultural fields.

Behaviour

Red-winged Blackbirds are highly social, often forming large flocks outside the breeding season. Males are territorial during breeding, perching prominently and displaying their red epaulets while giving their distinctive 'conk-la-ree' call.

They forage on the ground or in low vegetation, probing for insects and seeds.

Vocalisation

The male's song is a distinctive 'conk-la-ree' or 'o-ka-lee', often accompanied by a display of his red shoulder patches. Females produce a series of chit or check calls.

Both sexes use various chips and chatters for communication within flocks and during territorial disputes.

Nesting & Breeding

Breeding season for Red-winged Blackbirds typically begins in late spring. Males establish territories and attract females with conspicuous displays and vocalizations.

Females construct cup-shaped nests using grasses and sedges, often woven around several upright stems in marshy vegetation. They lay 3-4 pale blue-green eggs with dark markings.

Incubation lasts about 11-13 days, performed solely by the female. Nestlings fledge after 11-14 days, with both parents contributing to feeding the young.
