Q. Do all birds migrate?
A. Not all bird species migrate, but most do.
Migration is defined as the seasonal movement of birds, north in the spring from the wintering grounds and southward in the fall from the breeding grounds. Among the birds that are resident, or do not migrate, are many grouse, ptarmigan, and quail species, many owl species, pileated, red-bellied, downy, and hairy woodpeckers, white-breasted nuthatch, Carolina wren, northern cardinal, wrentit, ring-necked pheasant, Townsend's solitaire, common raven, gray jay, and northern mockingbird.
