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 30% of wildlife watchers report a Red-winged Blackbird sighting in Palo Verde National Park on a given day, based on 627 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 36th most-seen of the 274 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Red-winged Blackbird in Palo Verde National Park on a given day, against about 20% in January–February and November, the lowest months. That is one of Palo Verde National Park's wettest months, with about 300 mm of rain against almost none in February.
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.
8th of 56
Of the 56 parks where we can rate Red-winged Blackbird sightings, Palo Verde National Park ranks 8th at about 30%. 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.
Same family: Icteridae
The closest relatives of the Red-winged Blackbird that you can see in Palo Verde National Park (family Icteridae, New World Blackbirds and Orioles) are Great-tailed Grackle (about 40%), Streak-backed Oriole (about 30%) and Baltimore Oriole (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-winged Blackbird is recorded against all the birds logged in Palo Verde National Park (627 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.
