Important Bird Areas

Cranesville Swamp

Maryland

Cranesville Swamp is a peatland bog, one of only a handful of such sites in Maryland. A ?frost pocket? on the Allegheny plateau, it supports vegetation, including sphagnum bog, hemlocks and tamaracks, typical of more northerly climates, and also hosts a bird community of species at the southern edge of their range. Cranesville Swamp is owned by The Nature Conservancy. It spans Maryland?s western border and most of its 1648 acres lie in West Virginia.

Ornithological Summary

Cranesville Swamp supports a community of birds confined to mountain bog habitat in Maryland, including Alder Flycatcher, a species listed by the DNR as In Need of Conservation, and a rare species, Northern Waterthrush. Nashville Warblers and Northern Saw-whet Owl, mountain bog species once found here, may no longer breed or do so only occasionally. Several northern forest birds rare as breeders in Maryland, despite being common at other seasons, nest at the swamp. These include Canada Warbler, an Audubon WatchList species, Golden-crowned Kinglet, Red-breasted Nuthatch, Hermit Thrush, and Magnolia Warbler.
