This article is concerned with those bats that frequently enter man-made strutures and cavities including attics, lofts, barns and belfries in the Capital Region from Albany - Saratoga Region's as well as the Castkills and Chatham -Columbia County area
The Big Brown Bat
The Big Brown Bat weighs 2-3 times more than any other NY cave bat and has a wing span of 13". Most Big Browns are tolerant of cold temperatures; it often winters near the entrance of caves and mines, and is one of the state's only bat species to regularly winter in buildings including attics and belfries. The Big Brown often raises its young in buildings as well as trees; it is one of our most common summer bats. The Big Brown is most responsible for bats in the winter coming down into the living area of homes. The Big Brown thinks its spring when the heat turns up or they are awakened from hibernation, hungry and probably cold. The Big Brown will scratch on the sheetrock under the insulation in your attic to stay warm. Residents may hear this above their head and become alarmed. In the winter months this scratching or a sudden appearance is a dead giveaway of a bat's hibernating/roosting in your attic. Professional Service is needed immediately.
