I break for Porcupines!

In a fit of boredom I was looking at the roadkill tracking websites for California and Maine.  I wasn't overly surprised by some of what I saw on their sites, for instance California has a lot of dead racoons, skunks, and opossums.  But when I looked at the Maine site I was saddened by what I saw, lots of dead porcupines. I have a soft-spot for porcupines because they get a bad rap. Really who can resist this level of cuteness in a woodland creature?  I know what your thinking they have razor sharp spikes that they can throw at you, how can you think it's cute?  First of all let's do a little experiment. Stand up and move away from whatever your reading this on and in your best headbanger move bang your head forward making sure not to hit anything.  Are strands of your hair stuck into the nearby wall? No, I didn't think so.  A common urban myth is that porcupines can throw their quills, those spiky things on their backs, which is not true. They can throw their quills about as well as you can throw your hair across the room after all a quill is nothing more than modified hair.  Porcupines when they feel threatened will whip their tails around and whack at their attacker leaving them full of some of those 30,000 quills. Porcupines will also arch their backs, raise their quills in a defensive posture, and shake when their attacker gets near increasing the chances of one or more of the quills having enough force to get lodged in their attacker.

These quills are a work of art when it comes to animal defense. They are hollow and barbed (hooked) at one end which allow them to stick easily into anything. Once these quills are embedded in something warm they expand making them harder to remove. Muscle twitching also helps to drive the quill deeper into an animals or human's skin. So the best thing to do if you end up with a porcupine quill in you is to relax that muscle and pull the quill out with a pair of pliers. If you forgot to bring your first aid kit with you have no fear porcupine quills have a antibacterial fatty layer on them, so you have a little while to get back to where you can was your wound and put a bandage on. 
Quills are not just good for defense they also serve the purpose of helping the porcupines to float. Quills are hollow in the inside and since porcupines have about 30,000 it acts as a built in life preserver which is useful to an animal which is an avid swimmer.

So why are their so many dead porcupines in Maine? Probably because their is so much great habitat for them there. They love to eat hemlock, birch, maples, and skunk cabbage just to name a few.  They roam through forests and wetland areas following their nose to tasty bits.  While they have a great sense of smell they have bad eyesight.  Porcupines also have a love of salt which has led them to eat such crazy things as outhouse seats and wooden canoe paddles.  During some times of the year the porcupines maybe drawn to the roads because we humans salt road surfaces and porcupines being slow moving dark colored nocturnal animals motorists just don't have enough time to get out of their way.  The rest of the year they just fall victim to trying to cross the roads to get over to a preferred foods and not moving fast enough.

TURKEYS!!!

Staying in with the holiday spirit I thought I would wax poetic about about turkeys since this time of year I see them everywhere. Wild turkeys travel in a gang, like this one.

I ran into these three turkeys while out for a walk in one of Madison, WI city parks. Only thing was they were not alone.

THEY JUST KEPT COMING! All told there were 16 turkeys lurking in the woods.  I did my best to give them their space, but wherever I went they were pretty close behind. I zigzagged they zigzagged, I turned around and jogged back down the trail they jogged down the trail after me.

Now most people I know would not be worried by this, but me I'm scared of turkeys. You might say it is an irrational fear, but have you ever seen the spikes on the back of a turkey's leg?
Males use these formidable spikes to injure or kill other male turkeys during mating season. So imagine a large 6-24 pound turkey flying at your head with spikes a blazing, scary thought am I right?  Did I mention they can fly at speeds of up to 54 miles an hour?

The coolest fact I know about turkeys is using their gizzard they can crush 24 English walnuts at once.  The gizzard is a small muscular pouch in the turkey's neck which helps to break up their food into smaller pieces for digestion. This pouch often has small rocks or pebbles in it to help crush anything in it.

While the wild turkey's domestic cousin maybe fairly dumb, if you watch a group of wild turkeys you'll find they can be fairly inquisitive.  Joe Hutto’s  book and also the Nature documentary he talks about his experiences raising wild turkeys and watching their inquisitive nature. While I am not advocating adopting wild animals the documentary makes for interesting watching.


Keep your eyes peeled the next time you take a walk in the woods for smart, fast flying, spike caring heavy birds!  Just watch out for your head.

My Winter Slump......

The last few days were wonderful daytime highs in the 60 light breeze life was good. This morning I woke up to what seemed like a awesome fall morning, which lasted all of three hours. By 11:00am this morning the cloud celling had lowered the wind started to pick up and the snow started falling once again. Don't get me wrong I love going for walks in the snow enjoying the peaceful solitude and the subtle squeak of the snow under my boots, but this is our 4th significant snow so far this fall and as far as I'm concerned it is a little too early for me to be seeing this much snow. 

This somehow got me to thinking about animals who never EVER have to wake up on a particular cold morning stuff themselves into 4 layers of clothes and trudge off to work.  Marmots and ground squirrels I salute you for being the smartest animals on the planet. Marmots and ground squirrels spend a whopping  8 months of the year in hibernation.  Marmots generally crawl from their burrows in mid-May. From Mid-May through early September their days are spent eating food and catching some rays. About 44% of the time they are above ground in the morning hours is spent basking in the sun which helps them to get the most energy out of the food they eat. 

Marmot awaits hikers on the trail.

 

 

Now life is not all rosy for my marmot friends since they are a little on the portly side, as far as rodents go, there are a bunch of animals just waiting to eat them for lunch. Hawks roam the skies waiting to catch one alone. Coyotes, foxes, and weasels looking for a snack sniff out their underground burrows and dig them up.  Marmots are also trolling the talus slopes looking for nutrients just like all the other animals. Most of the animals nutrients comes from the food they eat or animals bones and antlers they gnaw on. However, there is the occasional added bonus from hikers who pee on the edges of the trail.  Yes, marmots and other animals will eagerly eat your pee marked ground in order to get nutrients they need to survive. And I'll throw this out there as a word of caution yes, marmots are small other animals which will also go after your pee are not and are WAY more dangerous, so please no marking your territory along the edges of the trail.

Two marmots fight over pee soaked ground.

 

 



By mid-August my marmot friends are beginning to feel sluggish and by early September have crawled back into their burrows for the last time until next year.  Around this time the weather starts to change in the high country. Stiff 45-50 mile an hour winds buffet the treeless slopes as the snow starts to fall from a cold grey sky.

Sleep well my marmot friends and may you safely avoid the weasels and coyotes who would love to eat you as you sleep. 

Humm.......Maybe Pika Next?

Maybe it is because I have been sick the last few days or maybe I have been in the woods too long, but my mind has been running amuck with ideas.  It all started when I read this article in The Guardian the other day.   I'll be the first to admit I don't understand the whole point of this experiment, but maybe it would help with research on pikas.

Pika are fun little critters only 6-8 inches in size and they are cute!  (Don't believe me check out the photos others have posted on Tumblr.)  In my life I have seen exactly one, yep one.  Not from lack of trying on my part either I've hiked high into the alpine regions of many parks and yet have seen only one of the elusive little buggers.

Problem with trying to see one is they are shy creatures, probably because there are so many things looking to eat them like golden eagles, weasels, foxes, coyotes, etcetera.  Also they don't do well with heat.  Their normal body temperature is 105F degrees and if their body temperature gets to close to 109F they can die.   There is a lot of research being conducted on how climate change is effecting populations of pika and the outlook is not good in most cases.  But with the help of ordinary people scientists have been able to map 139 new pika locations.

So what has this got to do with glow in the dark rabbits you ask?  What if in response to a warming climate they are foraging more in the evening and less during the day?  Small brown animals out in the evening would be very hard to spot.  Since pika are the smallest member of the rabbit order would it be possible to insert the jellyfish gene into pikas the same way they did to the rabbits?  I'm not suggesting we do it to a lot of them just 4 here and there just to see if they are changing foraging patterns in response to a warmer climate.

Just a thought.

From A Kid's Toy To Science Experiment.

It is always fun for me to see how scientists get inspired. A former coworker of mine was inspired to study bees after watching a beekeeper remove a colony of wild bees from her house in an old record player case.

Well now it seems that a child's toy magic wand has inspired one scientist to look a little closer at the spider webs and how they work.   This research will make spiders even cooler than they already are.

Most people don't realize that spider webs are a very time consuming process and that every day most spiders consume their webs and then respin  them all over again. After all you can't catch a tiny gnat for lunch if there is a hole in your web large enough for it to fly through.  Since these webs take a lot of time and resources to build spiders want to protect them from possible damage.  Our human eyes sadly do not allow us to see spider webs really well unless the sunlight is hitting it at just the right angle, but to birds these webs stick out like giant neon signs warning them to pull up, go around, get out of the way!  Some spiders also create doorbells, a strand of silk between one of the spider's legs and the web, so they don't always have to sit in the center. As soon as the web starts moving doorbell rings and the spider darts onto the web and grabs hold of it's prey before holes get ripped in the web. 

Did you ever wonder how a spider can walk across a web and not get stuck but a fly gets stuck like super glue?  The secret is they have a coating on the hairs and their feet which creates a nonstick surface also by walking slowly across the web they have much less of a chance of getting stuck to it as they spin their webs and as they catch their prey. As a spider moves across their webs they are using their  many eyes to keep track of shadows and movement near by. While a spider can have anywhere from no eyes (cave dwelling spiders) to eight eyes they don't see very well and can mainly make out shadows and movement not what it is that is causing it.

Spiders are oh so cool.

And The Toughest Animal In The World Is.......

Every now and then someone will ask me either what my favorite animal is or what I think the toughest animal in the world is. Asking a naturalist this is a kin to asking a mother to pick a favorite child.   However the more I learn about this little bird the more impressed I am and it may be making the list of my top 10 coolest animals ever.

Standing a whopping 6-8 inches tall and weighing not much more than 1.5-2.4 ounces is the American dipper. 

 

 

 

This little pint sized song bird spends a lot of it time under water looking for aquatic insects.  Not just any old kind of water FAST moving water.  (Think of a human trying to stand up in some super heavy whitewater while trying to grab a cheeseburger off the bottom.)  To accomplish this herculean feat they have mighty long toes with some sizable toenails which allow them to grip rocks and pebbles underneath the water allowing them to walk along the bottom.  They  also have their own built in goggles called a nictating membrane which helps to protect their eyes from floating debris. Probably the most important adaptation is the extra-large preen gland which secrets oil to help waterproof their feathers.  Dippers can often be seen standing on rocks bobbing up and down. Scientists really don’t know why they bob up and down it may help them to see well.

 

 

Also these little birds are members of the polar bear club.  Then the weather starts getting colder and the rivers and streams they feed in start to freeze to they head for warmer climates.

 

Nope they just head for the nearest free flowing steam and plunge right in for a snack! 

This might just be the toughest animal anywhere!


Dippers can often be seen standing on rocks bobbing up and down. Scientists really don’t know why they bob up and down it may help them to see well. They are well   Dippers are active in this area even in winter seeking out streams which are not frozen. anding a

EVERYONE OUTSIDE!!!!

Over the last two weeks I have been stuck indoors in what is known as seasonal training. I define this a torture and I'm sure it is against the Geneva Convention to keep people normally used to being outside confined in a small space being made to watch hour after hour of PowerPoint presentations.   So after almost two weeks of this I needed to get OUT!  After a BBQ the other night I grabbed my camera and walked about 1/4 mile away from our hotel to a field just outside the entrance to Glacier National Park. I plunked my butt in the middle of a field full of flowers and sat there watching the sunset behind the famous Lewis Thrust Overfault.

I hadn't been there more than a few minutes before a coyote on his nightly rounds stumbled apon me.  He cocked his head a little to the side and gave me this look of "what are you doing in my field?"  After a few glances he went back on his way.  The sun sank lower towards the horizon painting the sky a vibrant pink and throwing the last rays of sun onto the snowfields.

 

I sat there and watched the dying light play across the sky, suddenly becoming aware of a commotion taking place about a mile down the road. A large female moose lumbered from the willows and strolled down the street ignoring the paparazzi gathered on either side.  I glanced back to the sunset in front of me and who should appear but mister fox with a mouth full of food heading probably back to his den site.

 

 

With the chill in the air growing more intense and twilight giving way to night I strolled my way back to the lodge not realizing I was being watched from behind. As I neared the lodge a coworker shouted

 


from the third floor balcony that there was a moose behind me.  I turned and sure enough there bolting for the nearby hillside was a female moose suddenly startled by a sudden group of two legged animals in her path.

This week get outside and find a spot near a pond, in a field, or even a city park. You never know who you might see.
