Human disturbance is especially harmful to the state’s bat populations since the arrival of the disease known as white-nose syndrome, a fungus that has killed more than 90 percent of bats at hibernation sites in New York due to how closely bats congregate in caves during winter months.
Even a single, seemingly quiet visit to a cave can cause bats to temporarily increase their metabolism and expend significantly more energy than normal. » Continue Reading.
At the start of National Bat Week, the New York State Department of Environmental Conservation (DEC) has urged outdoor adventurers to suspend exploration of cave and mine sites that may serve as seasonal homes for hibernating bats.

Context is critical, right? Years ago I took a second job loading trucks at night, and a few guys on the dock had what you might call “white-nose syndrome.” All I had was coffee, so they could work faster than I, though they spent a lot more time in the rest room. I hope they eventually recovered.
Addiction is a serious and potentially life-threatening matter, but from a bat’s perspective, white-nose syndrome is something even more devastating. This disease, which is nearly always fatal, has killed 80% of the bats in the Northeastern U.S. in less than a decade. Initially found in central New York in 2007, white-nose syndrome now affects bats in 25 states and 5 Canadian provinces. Since it was first identified, it has felled more than 7 million bats, leaving once-packed hibernation sites, or hibernacula, empty, and pushing some species to the edge of extinction. » Continue Reading.
Despite remarkable similarities in appearance, flying styles and behaviors, not all bats are created equal. In the Adirondacks, there are approximately nine species of these dark, winged mammals during the summer months, yet all possess their own unique physical characteristics and habits.
The manner in which bats deal with the total lack of flying insects that occurs with the onset of winter is one feature that illustrates how bats are different. Even though more than half the species that populate our region migrate to and then enter caves or mines that extend deep underground, all have definite preferences for below the surface. While some species proceed far from the entrance in order to reach warmer and damper locations, others favor cooler and drier spots closer to the world above. » Continue Reading.

Anyone entering a northern long-eared bat hibernation site from October 1 through April 30, the typical period of hibernation for bats, may be subject to prosecution.
Human disturbances are harmful to the state’s bat population following the spread of the disease known as white-nose syndrome, which has killed more than 90 percent of bats at most hibernation sites in New York since it was first discovered in a popular cave near Albany. » Continue Reading.
The U.S. Fish and Wildlife Service (FWS) has proposed weakening protections for the northern long-eared bat by reducing its stats from “endangered” to “threatened”. Advocates for endangered species say FWS has included a special rule aimed at conceding to pressure from industries and politicians critical of the Endangered Species Act.
The less-protective proposal comes despite the fact that the bat, which has been decimated by the fungal disease known as white-nose syndrome, has already declined by up to 99 percent in the Northeast. » Continue Reading.
August is when a majority of wildlife families dissolve, as the young gradually start to wander from their parent’s care and begin finding food for themselves and developing the strategies for surviving on their own. Among the many maturing creatures achieving independence as summer wanes are the young of the various species of bats that exist within the Park. Regardless of their habitat and the types of bugs on which they prey, all juvenile bats are now capturing their own food and exploring their surroundings without the supervision of their mother. » Continue Reading.
The U.S. Fish and Wildlife Service proposed Endangered Species Act protection today for the northern long-eared bat, which has been devastated by the disease known as white-nose syndrome. The agency declined protection for the eastern small-footed bat.
Colonies of the northern long-eared bat affected by white-nose syndrome have in many cases experienced 100 percent mortality. Protection for the bat is the result of a landmark agreement with the Center for Biological Diversity that requires the agency to make protection decisions for 757 species. Before today’s decision, Indiana bats were the only bat in the Adirondacks on the Federal Endangered Species List (listed in March 1967).
The New York State Department of Environmental Conservation (DEC) has announced the results of last winter’s survey of the hibernating bats in New York. The survey was a cooperative effort among state wildlife officials, the U.S. Fish and Wildlife Service and numerous volunteers to monitor the effects of white-nose disease, a fungal infection that has devastated regional bat populations since it was first documented in a cave near Albany (in Schoharie County) in 2006. Since then white nose disease has spread throughout the South, Midwest, and eastern parts of Canada. Earlier this month new cases were identified for the first time west of the Mississippi in Missouri.
According to a study in Science, little brown myotis, a once common local species, has experienced a population collapse that could lead to its extinction in the northeastern US within 20 years. The Forest Service recently estimated that the die-off from white-nose will leave 2.4 million pounds of bugs uneaten and a financial burden to farms. A growing scientific consensus agrees the cause is Geomyces destructans; there is still debate over whether or not it was introduced from Europe by cavers.

Interest in bats has steadily increased over the past several years as the problem of white-nose syndrome has become more acute, especially in the Adirondacks. As people become more familiar with this unique group of mammals, numerous questions regarding their ability to survive the ravages of this rapidly spreading disease continually arise.
While there are answers to a few questions, most have none, other than “best guesses” or “ideas” from very intelligent wildlife biologists who have regularly studied these creatures. However, even the experts are limited in responding to some questions about bats, as there has not been much research conducted into numerous aspects of their natural history and population status, especially here in the Park. Although some features of bats are well known, many habits and behavioral traits of these winged animals still remain a mystery. » Continue Reading.

Biting insects are the price of admission for playing in the backcountry of the Adirondacks. But this year these pests seem to be more plentiful and ferocious than in years past. This is particularly true for the blood-sucking scourge known worldwide as the pesky mosquito.
Last month I experienced the large number and ferocity of mosquitoes first hand during an eight-day trek within the remote interior of the Five Ponds Wilderness in the northwestern Adirondacks. Saying mosquitoes were plentiful would be a vast understatement given the near-Biblical proportions of the blood-suckers encountered there. » Continue Reading.
Yesterday I visited an old graphite mine in Hague that once harbored the largest population of wintering bats in the state. Back in 2000, state scientists estimated that the old mine contained 185,000 bats. Last winter, they found only a few thousand.
Such are the devastating effects of white-nose syndrome [pdf], first discovered in upstate New York in 2006. Since then, the disease has killed 90 percent of the state’s bats and spread to hibernacula throughout the Northeast and as far south as Virginia. » Continue Reading.
At long last, we come to the end, the final chapter on Adirondack bats. I left the most common species for my last piece because what is common today may be gone tomorrow. I speak of the little brown (Myotis lucifugus) and big brown (Eptesicus fuscus) bats, those furry cave-dwellers who have been most heavily impacted by the fungus-based disease now known as white-nose syndrome (WNS). Every hibernaculum in New York has now been diagnosed with the disease, and in some of the caves, these bats have experienced over 90% mortality. It’s a sobering fact. » Continue Reading.
To the average Joe, an Indiana bat (Myotis sodalis) is not a terribly impressive animal. It is a smallish, brownish bat, often mistaken for a little brown bat (another less-than-dazzling member of the clan). A scientist in the know, however, can detect small differences to tell these species apart, such as the length of the toe hairs (I kid you not), the length of the ears, the color of the snout, the amount of shine to the fur, or the presence of a keel on the calcar (a spur of cartilage that gives some rigidity to the trailing edge of the wing membrane near the bat’s foot). » Continue Reading.
