Unusual mortality events were detected at four hibernacula in New York between early March and late April 2007. Bat carcasses and parts of carcasses were estimated to number in the thousands within Hailes Cave where this years winter survey count of 7,296 live bats was 47% of the 2005 survey total. At Schoharie Cavern, 125 carcasses were found and the survey count of 478 live bats was 36% of the 2006 total. The number of carcass collected at Knox Cave (125) and Gages Cave (805) represent 20% and 83% respectively of the most recent winter counts. All of these caves are within a 12 km radius in Albany and Schoharie Counties, NY. With two exceptions that may be unrelated, there were no reported mortality events elsewhere in NY,VT or PA. It is clear that many bats died outside of the hibernacula, and that mortalities began no later than early February. Winter submissions from the Albany County region to the NYS Health Department (DOH) of Myotis spp. were 10 times higher than mean submission rates over the last decade. Anecdotally, the number of observations reported by the public of bats flying in a wide variety of winter conditions were the highest in the experience of Department of Environmental Conservation (DEC) and DOH staff. Carcasses collected both inside and outside of Hailes Cave were emaciated, although necropsy results by pathology units at DEC and USGS are not yet completed. Many carcasses at Hailes and Schoharie had been predated or scavenged. We do not yet know the exact species composition of the kills, or the cause or causes of these mortalities, and investigations are continuing. We will discuss potential explanations including disease, and the possible relationship to record warm temperatures that occurred during the early winter.
