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.

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.
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.
When most people think of bats, they either think of caves, or their attics. While a good number of species are colonial and hang out together in caves (in winter) or attics/barns/bridges (warmer months), we do have three species here in the Adirondacks that live solo lives in the woods. These are the red, hoary and silver-haired bats. Not only is their lifestyle not what we expect, but they also look much different from what we expect, for these are the most colorful bats in our part of batdom.
Today we will contemplate the red bat (Lasiurus borealis). Like any true redhead, the red bat is actually more of an orangish color, sometimes leaning more toward the yellow end of the spectrum. The males are more brightly colored than the females, which makes sense when one considers the rather exposed lifestyle this bat leads (a female can more easily hide with her young if her coloration is dull, kind of like birds). » Continue Reading.
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.
In February 2006 a caver photographing hibernating bats in Howe Caverns near Albany noticed some bats with an unusual white substance on their muzzles. The following January New York Department of Environmental Conservation (DEC) biologists documented more bats with white noses, bats behaving erratically, and numbers of dead bats. Since then NY DEC biologists have been monitoring more than 30 winter bat “hibernacula” in New York’s caves and mines. Over the past three years 93% of the bats in the Northeast, afflicted with what is known as “white-nosed syndrome,” have died. According to the US Fish and Wildlife Service, more than a million bats have perished from New Hampshire to Virginia in the past four years! » Continue Reading.
Bill McKibben, author of The End of Nature, has been rallying support from around the world to call for a fair global climate treaty. Wildlife biologist Al Hicks trying to prevent the extinction of bats in the Northeast. McKibben (left) will be the keynote speaker at the annual meeting of the Adirondack Chapter of The Nature Conservancy and the Adirondack Land Trust on Saturday, August 15, at the Newcomb Central School in Newcomb, NY. Hicks’s lecture, The End of Bats in the Northeast?, is one of three field trip/educational opportunities being offered before the meeting formally kicks off at 1:00. The event is free and open to the public. Participants are asked to register in advance.
McKibben is founder of 350.org, which according to the website, “is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis–the solutions that justice demand.” Their stated mission is to”inspire the world to rise to the challenge of the climate crisis–to create a new sense of urgency and of possibility for our planet.” The number 350 refers to parts per million, and represents the level scientists have identified as the safe upper limit for CO2 in our atmosphere.
The meeting will also feature a conservation update from Michael Carr, delivering the latest news on historic land protection projects involving the former Finch, Pruyn & Company lands and the Follensby Pond tract—175,600 acres in all. Attendees will find out how sustainable forestry fits into part of the conservation plan.
At 11:00 a.m. in the Newcomb Central School Auditorium, state wildlife biologist Al Hicks will give an up-to-the-minute account of “white-nose syndrome,” a mysterious affliction causing bat populations in the Adirondacks and at least nine northeastern states to plummet. Hundreds of thousands of bats, including animals from well-established colonies in the Adirondacks, have already died. Hicks has been on the frontlines of this environmental crisis since the outbreak was first discovered in 2007.
Participants should plan to arrive around noon for the annual meeting, or before 11:00 a.m. to attend the special lecture. Bring a bag lunch or call ahead to reserve an $8 lunch from Newcomb Central School students raising money for their trip abroad.
To register for this event, reserve a bag lunch, or obtain more information, contact Erin Walkow at (518) 576 – 2082 x133 or firstname.lastname@example.org.
Bats are on my mind these days, thanks to the work I’m doing with the DEC survey. One of the other volunteers, who is also working on a bat project for college, just sent me an email about a baby bat that had fallen from its roost and the students who picked it up. To make a long story short, the bat was killed so it could be tested for rabies because the students had handled it without protection. So, I thought I’d dedicate this post to Proper Procedures When Encountering a Bat so that future tragedies of the same sort can be avoided.
Scenario #1: You are walking along and you see a bat on the ground – what do you do? Ideally you leave the bat alone and continue on your way. However, there are circumstances that might make this action unviable. So, first you should acertain if the bat is injured or sick. Injured bats should be taken to rehabbers. Sick bats should be sent to the state for rabies testing. Sometimes bats simply fall from their roosts (have you ever fallen out of your bed?); given the chance to do so, they will climb back up to safety. If it is a juvenile, it may not be able to climb back up, so assistance might be needed.
Never, never, never handle a bat without gloves. Better yet, don’t handle it at all. If you need to collect a bat, the best way to do so is to use a can (or jar) and a piece of cardstock. Gently place the can over the bat and gently slide the card underneath, effectively trapping the bat inside the can. If the bat is uninjured and healthy, take it outside and let it go. You can do this most easily by laying the can down on its side and walking away: the bat will crawl out, find a place to climb, and then fly away. Better yet you can empty the can gently on a branch so the bat will be able to fly off immediately.
Scenario #2: A bat flies into your house – what do you do? The best thing to do is determine what room the bat is in and then isolate it there. Close all doors and open one window. Turn out all the lights. Leave the room. The bat will find that open window and fly out. There is no need to panic. If there are no windows to open, or doors to close, follow the procedure above with the can. Eventually the bat will land somewhere (on a curtain, on a wall), and you can collect it there.
Scenario #3: Bats are roosting in your attic – what do you do? The odds are if you have a good number of bats in your attic, or barn, or garage, you probably have a maternity colony. This is a group of pregnant females who have sought your attic/barn/garage as the perfect place to give birth and raise their young. They are looking for locations that are warm (really toasty roosts help the babies mature faster) and have plenty of room to move around if it gets too warm, or too cool, in one spot. If you have a maternity colony, they will give birth by June. Baby bats are not flighted for several weeks. Once the young can fly and feed on their own, the colony moves on, usually at the end of the summer. Hiring an exterminator is really not a great idea, especially now that bat populations are declining. These days the thing to do is exclusion, wherein you locate all the entrances and exits the bats are using and seal them up…after the bats have left in the fall (or before they return in the spring). You don’t want to exclude the adults while the babies are still in the roost – they will starve to death and you will have a smelly mess. You can try erecting bat boxes nearby to provide an alternative roost site. These alternative roosts will have to be large enough to provide the bats with the conditions they need to raise their young (similar to those in your attic/barn/garage); the little boxes you can buy at garden or hardware stores are not going to cut it.

Myth Busting: Forget everything your mother and friends told you about bats – chances are they are wrong.
1. Bats do not fly into your hair/head, or at least not on purpose. Have you ever accidentally walked into a wall or doorway? My theory is that in those cases in which a bat has hit someone in the head, it was simply a miscalculation on the bat’s part. It may even have been a juvenile that is still getting used to flying and using its echolocation.
2. Bats are not aggressive. As a matter of fact, they are actually rather shy animals, and many species are easily tamed. Bats only bite when cornered and given no opportunity to escape (like any other animal).
3. Bats drink your blood (after biting you on the neck). Well, first off, the only bats we have here in New York are insect eaters. You are not an insect, so you are safe. But yes, there are vampire bats – in Mexico and Central America. There are only three species of vampires; two of these species feed on birds. Only one is dependent on mammal blood, and it mostly drinks from cattle (now that cattle have moved into its habitat and are easy prey). These bats are all very small, and at most they drink (lap, actually, like a cat) a tablespoon of blood; more than that and they cannot fly.
4. Bats are dirty. Actually, bats are very clean animals. They groom themselves (and each other) almost as much as a cat does.
5. Bats are blind. Since people cannot see at night, they presume nothing else can see at night either. Therefore, bats must be blind because they fly at night without any difficulties (and we know that the blind can often navigate very well). In fact, bats have good eyesight, but they depend on echolocation (it’s like SONAR) to navigate at night and find their prey.
6. Bats are flying mice. Well, they may look like mice with wings, but bats are not even closely related to mice. As a matter of fact, bats are in a category all their own: Chiroptera (which means “hand wing”). There is nothing else on this planet like them. And, just because I love this fact, believe it or not almost one-quarter of all mammal species are species of bats! That’s right. Scientists have identified approximately 4000 species of mammals around the world, and about 1000 of these are species of bats. That should give us all an idea of just how important they are.
What about rabies? Any mammal can get rabies. Rabies is a virus that is tranmitted through saliva, usually from a bite. In general, the odds of a bat having rabies is set at less than one half of one percent. You are more likely to get food poisoning at a church picnic. That said, there are areas that do have higher incidents of rabies in bats. The last time I checked, New York listed it as 8%. Rabies testing requires the testing of brain tissue, which is only possible after the animal is deceased, so it’s not like a healthy animal will be released if its test is proven negative.
So how do you know if the bat is sick and should be sent for testing? Usually when bats get rabies, they exhibit a passive form of the disease. In other words, they do not become aggressive and charge at you, foaming at the mouth. If you encounter a bat that is lethargic and just not acting normally, it is probably sick. Such bats should be sent for testing.
With the cataclysmic decline of our most common bats these days, I think each of us should think twice when we encounter a bat. Don’t handle it. Don’t squash it with a broom. Help it leave your house safely. Bats have important roles to play in our ecosystems, even here in the Adirondacks. We should do everything we can to help those that remain survive.
What is your favorite bird/animal/flower? This is a question I am often asked, and for me it is a difficult one to answer because there are too many fascinating things out there to select just one favorite. That said, I am especially fond of bats. They are highly misunderstood animals that are actually linchpins in many ecosystems. If more people understood their importance, they might be as popular as baby seals and elephants. Sadly, it often takes tragedy to bring around a change in feelings, and for our bats, that tragedy is White-nose Syndrome (WNS). » Continue Reading.
Marsupials – the possum. The Adirondacks is in the upper range of the possum, so you often find them with signs of frostbite, particularly their ears. Amazingly they give birth just 12 1/2 days after mating.
Shrews and Moles – There are six different species of what are called “red tooth shrews”. They have an average life span of just a year and eat almost continuously. Our shrews have a toxin in their saliva which paralyzes it’s prey. The pygmy shrew weighs less then a dime making it (arguably) the smallest mammal in the world. The water shrew dives (mostly in streams) for its prey, including frogs and fish. They are often caught in minnow traps. We have two moles – hairy tail (the most common) and the star nose (uglier and aquatic). » Continue Reading.
