Abstract
The wintering range of the Great Blue Heron (Ardea herodias) extends further north than does that of any other member of the Ciconiiformes in North America. The northern limits of its range extend along the Pacific coast into southeastern Alaska, into Massachusetts on the Atlantic coast, and inland into southern Montana (Palmer 1962). In the northern part of its range, severe winter weather may persist for weeks or months. Little information is available regarding either the response of individual Great Blue Herons to severe winters or the effects of these conditions on populations. In this paper, we report our observations on a small heron population in Oregon and Washington that was exposed to a severe winter.
