"During the 1991 breeding season an inventory was made of Great Blue Herons (Ardea herodias), Great Egrets (Ardea alba) and Black-crowned Night-Herons (Nycticorax nycticorax) nesting in the Canadian portions of Lake Huron (except for the waters surrounding Manitoulin Island) and the lower Great Lakes, including Lake St. Clair and the upper St. Lawrence River. Canadian Lake Superior was not surveyed in 1991, so 1989 data are used as substitutes in this report"--Abstract.
