The rusty blackbird (Euphagus carolinus) is a medium-sized New World blackbird, closely related to grackles ("rusty grackle" is an older name for the species). It is a bird that prefers wet forested areas, breeding in the boreal forest and muskeg across northern Canada, and migrating southeast to the United States during winter.
Formerly abundant, the rusty blackbird has undergone one of the most rapid declines of any abundant bird species in North America in recent years, for reasons that are not well understood. Adults have a pointed bill and a pale yellow eye. They have black plumage with faint green and purple gloss; the female is greyer. "Rusty" refers to the brownish winter plumage. They resemble the western member of the same genus, the Brewer's blackbird; however, Brewer's has a longer bill and the male's head is iridescent green.
Their breeding habitat is wet temperate coniferous forests and muskeg across Canada, New England, the Upper Peninsula of Michigan, the Adirondack Mountains in New York and Alaska. Birds usually nest at the edge of ponds and wetlands with the cup nest located in a tree or dense shrub, often over the water. Emerging dragonflies... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rusty Blackbird sighting in Shenandoah National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 168th most-seen of the 186 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rusty Blackbird in Shenandoah National Park on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Rusty Blackbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 13
Of the 13 parks where we can rate Rusty Blackbird sightings, Shenandoah National Park ranks 12th at under 5%. The best odds are in Wrangell-St. Elias National Park (United States, about 20%), Wood Buffalo National Park (Canada, about 10%) and Point Pelee National Park (Canada, about 10%).

GBIF citizen-science records
It is estimated from how often the Rusty Blackbird is recorded against all the birds logged in Shenandoah National Park (12 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.
