How to identify it
Male dull black, female slaty, with yellow eyes in most seasons; 21-25 cm. [1][2][3]
Like male Brewer's Blackbird but less glossy, with a thinner bill. [1][2][3]
In fall distinctive with rusty feather edges and a buff eyebrow. [1][2][3]
Compared with the brewer's blackbird: Brewer's male is glossier with a thicker bill; ranges mainly west of Rusty's range. [1][2][3]
Compared with the common grackle: Longer-tailed and larger. [1][2][3]

Where it lives
Breeds in wet northern coniferous forest and muskeg with many lakes and bogs; in migration and winter favors trees near water such as wooded swamps and riverside forest, and forages in fields and feedlots. Canadian sources describe breeding near wetlands: sedge meadows, beaver ponds, muskegs and shrub-riparian areas. [1][2][3]
How it behaves
Migrates relatively late in fall and early in spring; strays appear in the West and Southwest most often in late fall [1][2][3]
Forages mostly walking on wet ground or wading in shallow water, alone or in flocks, sometimes joining other blackbirds in dry fields [1][2][3]
Mostly insects including aquatic ones (caddisflies, mayflies, dragonflies), also snails, crustaceans, small fish and salamanders, and seeds and waste grain in winter [1][2][3]
Song like the squeaks of a rusty gate; call a sharp check [1][2][3]
Take status not established
North Ground has not established meaningful legal take of this species. That is a gap in the evidence, not a finding that it is protected or that it is open.
Where it is found
Breeds from Alaska to Labrador and south to central British Columbia, northern Great Lakes, Vermont, New Hampshire, Maine and Nova Scotia; in the non-breeding season ranges south to Texas, the Gulf Coast and northern Florida, primarily the southeastern U.S. Assessed Special Concern in Canada.
