American Crows (Corvus brachyrhynchos) and Fish Crows (C. ossifragus) traditionally roost communally in winter. Across their range, many of these roosts have been in existence for a number of years. Very large roosts tend to occur in regions where there is abundant food, and also where northern migrants augment resident crow populations, as in Oklahoma (Good 1952).
