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.

The Adirondacks’ Endangered Bat: The Indiana Myotis
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.
Adirondack Bats: Keen’s and Long-Eared Myotis
Two bats that are often never mentioned (mostly because so few people have heard of them) are Keen’s myotis (Myotis keenii) and the northern long-eared myotis (Myotis septentrionalis). Both species have been found in the Adirondacks, but neither in great numbers. » Continue Reading.
The Adirondacks’ Smallest Cave-Dwelling Bats
Having covered the Adirondacks’ solitary tree-dwelling bats, it is now time to tackle the cave bats. There are a number of species to contend with, but today I am going to introduce you to just two: the eastern small-footed bat (Myotis leibii leibii) and the eastern pipistrelle (Pipistrellus subflavus).
The small-footed bat, as you no doubt guessed, is noted for its petite terminal appendages: it has small feet, only about six millimeters long. I’ve never seen any data on the size of other bats’ feet, but one must suppose that they are significantly larger with respect to the size of the bats in question. » Continue Reading.
Two More Caveless, Summer-Only Bats
Since October is quickly drawing to a close, I am going to combine two bats in today’s article, the hoary bat (Lasiurus cinereus) and the silver-haired bat (Lasionycteris noctivagans). These are the last of our caveless, summer-only bats and also our only other chiropteran residents that have striking coloration. » Continue Reading.
October is Bat Month at Adirondack Almanack
Ah, October; the month when summer has truly fled and winter can be felt in the air. Leaves explode in color and then lose their grip on life. Geese and other waterfowl beat a hasty retreat for warmer climes. Some flowers we typically see in the spring are apparently confused and put out a few end-of-season blossoms. And everywhere we turn, yards and businesses are decorated for Hallowe’en.
In keeping with this time of year, I’ve decided to bless you all with a series of articles about one of my all-time favorite animals: bats. I know, I know – I say this about so many animals, but truthfully, bats do top the list. Perhaps this is because they are so reviled by the majority of people and I love to root for the underdog. In fact, this was probably why my interest was piqued in the first place. But as I learned more and more about bats, I discovered just how fascinating these winged mammals are. » Continue Reading.
