The Yellow rail is a small, secretive rail that is seen and heard far less than any other rail in Oregon. Males vocalize during the breeding season with a five-note tic-tic, tic-tic-tic repeated incessantly during hours of dark, and call infrequently during the day. The call sounds much like two small rocks being tapped together.
Yellow rails are quite small and have a white patch on the trailing edge of the inner wing, more extensive than that on juvenile Soras. Males in the breeding season have a distinct yellow bill and are slightly larger but otherwise sexes are alike. Chicks are downy black and have a pink bill.
