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 Houston on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 285th most-seen of the 302 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 Houston 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.
Among the best
Of the 20 cities where we can rate Rusty Blackbird sightings, Houston ranks 19th at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%), Washington (United States, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Rusty Blackbird is recorded against all the birds logged in Houston (8 verified sightings), 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.
