The red-winged blackbird (Agelaius phoeniceus) is a passerine bird of the family Icteridae found in most of North America and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the Southern United States.
Claims have been made that it is the most abundant living land bird in North America, as bird-counting censuses of wintering red-winged blackbirds sometimes show that loose flocks can number in excess of a million birds per flock and the full number of breeding pairs across North and Central America may exceed 250 million in peak years. It also ranks among the best-studied wild bird species in the world. The red-winged blackbird is sexually dimorphic; the male is all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Seeds and insects make up the bulk of the red-winged blackbird's diet.

Possible
About 20% of wildlife watchers report a Red-winged Blackbird sighting in Acadia National Park on a given day, based on 2,070 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 243 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April to June
In those months about 30% of wildlife watchers report a Red-winged Blackbird in Acadia National Park on a given day, against under 5% in August–October and December–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Red-winged Blackbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
20th of 56
Of the 56 parks where we can rate Red-winged Blackbird sightings, Acadia National Park ranks 20th at about 20%. The best odds are in Point Pelee National Park (Canada, about 90%), Elk Island National Park (Canada, about 60%) and Riding Mountain National Park (Canada, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Red-winged Blackbird is recorded against all the birds logged in Acadia National Park (2,070 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
