Minnesota has around 446 bird species documented in October 2020, which the Minnesota Ornithologists’ Union Records Committee or MOURC also accepts. Of the species, 89 are accidental, 41 casual, eight introduced, one extirpated, and two extinct. The passenger pigeon and Eskimo curlew are the two extinct birds that no longer inhabit Minnesota.
The sandhill crane, the largest among all Minnesota birds, is commonly seen here between March and April, though it was rare at one point in time. Regarding the smaller birds, house sparrow, house finch, and American goldfinch top the list.
The common loon with a black and white body and red eyes has been the state bird of Minnesota since 1961.
