Nature Mystery Number 2!

I was out for a walk not too long ago and came across an awesome sight; evidence of a 6 foot tall beaver!!!!

Could this be a hold over from the last ice age which has been hiding out in the deep dark wood of Maine? After all during the last ice age there were beavers which measured about eight feet long and weighed close to 220 pounds.  What are the chances? Well, about as good as me seeing Bigfoot walking through the Oregon woods, not going to happen.

So, what is going on here?  Walk a few more feet further into the woods and you will find a beaver dam and the beginning of a beaver lodge. Since beavers can cut down trees as large as two feet around the beaver strolled by and thought hey this would make an excellent log for my beaver dam and got to chomping. Now while birch trees are a rather hard wood those amazing incisors they have easily make short work of this tree.  

Now the top set of chew marks is about 3-3 1/2 above the surface of the ground and the bottom cut is about 2 1/2 feet above the surface of the ground. Why is the top one so far off the ground?  It is a little hard to tell the how I took the picture, but there is a pretty significant hill on the left side of this picture. By looking a the wind blown shape of the tops of the surrounding trees it is obvious the wind blows over this area pretty strongly from the west (left side of the photograph.) As the wind blows across the hill the snow builds up deeper and deeper until the wandering beaver scopes out the tree for chopping.  As the winter nears an end the snow slowly starts to melt more of the base of the tree becomes uncovered and the beaver came back for another section of log. However, the beaver never had a chance to completely chip through the second section of tree before the snow melted out from underneath it.

Keep and eye out for mysteries in the forest around you!


Ps: If you have never seen just how into building dams beavers are take a look at the largest beaver dam anywhere in the world. Found in 2007, it is over 2,800 feet long!

It sounded like such a good idea until....

I'm all for saving money and making your own homemade stuff whenever possible, but somethings are really not worth the effort it takes.

Example number one: Maple Syrup

While I was living in Vermont my roommates excitedly exclaimed at breakfast "Hey let's make our own maple syrup!" They looked at me expecting me to share in their excitement, but were met only with a blank stare on my face. "It will be fun!" my inner-city Chicago roommate exclaimed. Now I had made maple syrup at a number of different jobs, so I knew how much work was going to be involved. After much begging they wore me down and convinced me to help. The first weekend went simply enough a friend loaned us all the supplies we would need; sap buckets, taps, to unused large plastic garbage cans to store our sap in, a 50 gallon oil drum set up which we could use to build a fire in and put our evaporating pan on top. He was even nice enough to help us tap the trees. After a few weeks passed we had enough sap to start the boiling process. As the sap boiled down we added more sap to the pan and at the end of day one of boiling we had made about 1/4 cup of syrup. 24 hours of boiling to make a measly 1/4 cup of syrup. This went on for weeks; collecting sap, boiling sap, splitting wood for the fire barrel. After about two months of doing this every weekend we had managed to produce 6 pints of smokey tasting backyard maple syrup. 192 hours of work to create 12 cups of maple syrup that is $160.00 a cup. On average it takes 25 gallons of sap to make one gallon of maple syrup and unless you have a large and preferably shallow pan to boil it in the whole process will take a very long time.

Example number two: Candle making

While I was working on one of the Boston Harbor Islands I realized there were tons of bayberry bushes all over the island.

Northern Bayberry Shrub

After making sure it was ok with my bosses, that I harvest some of the berries, I grabbed a bunch of shopping bags and started to collect them. Two large bags of  berries later I thought I had enough to make some candles.  Now the main reason I was doing this is because in my family it has always been a tradition to burn a bayberry candle all the way down to the bottom on New Year's Eve. The legend goes that if you burn a bayberry candle all the way to the stump it will bring you good luck and prosperity in the new year.  Bayberry candles can be hard to find and when you do 100% bayberry candles can be rather expensive. Few hours of simmering the berries I had a nice little waxy skim on the top of my water. Grabbed two more bags of berries and repeated the process making maybe 1/8 of an inch of wax. Now with the invention of the internet the great Google will tell you that you need anywhere from 1-15 pounds of berries to make enough wax for a votive candle or possibly a 3 inch pillar candle! However, preinternet the reference books I was reading were not very helpful telling me only that wax content varies based on the health of the plant. After simmering about 10 shopping bags full of berries I finally admitted defeat and had created maybe a birthday candle sized amount of wax.

About 12 years later I created another type of candles which worked much better and was way easier! Tallow candles. I was working at Lewis and Clark National Historical Park where I got to dress up in costume and teach people about what life was like for the Lewis and Clark Expedition.

Me Tending the tallow in buckskin clothing.

One of the school programs we have at the park the students learn quill pen writing, flint and steel fire starting, and tallow candle making. Obviously it is too dangerous to have fourth-graders boiling hot flammable fat so that job fell to me and the kids would wick up the candle molds that I would be filling with tallow. At the end of the day they each went home with a candle.

What you will need:
 50 pound of kidney beef fat- this you can get by calling your local grocery store or butcher shop and ordering it. You do need to specify kidney fat or you may end up with fat better used for sausage or suet feeder making.  You will also need a large pot and an open fire. Bring the fat to a rolling boil and boil and boil until you have something which looks like a clear amber liquid. When it cools it will turn a nice off white in color.

50 pounds of boiling beef fat.

Now if you manage to get your fire to the point where you can maintain a nice rolling boil you can render down 50 pounds of beef fat in about 8 hours. Watch the level of your fire or the beef fat will go up like a roman candle if the flames get too tall. Sounds simple your thinking what could possible be the drawback? Well there are a few. If you happen to own a dog the minute you bring the tallow candle into the house the dog will try and try and try to eat the thing. After all to a dog it SMELLS SO YUMMY! Second draw back is the smell when you burn it, think smokey hamburger, not exactly the mood you were hoping for around the Thanksgiving table. Oh, the biggest draw back will be how you smell after sitting around a fire pit boiling down 50 pounds of beef fat. It is a smell that will stick with you for weeks and nothing you do will make you smell any better. I'm sure the strange smell in my old car was lingering tallow stink.

Let this stand a cautionary tale that not all good ideas are really worth the effort. 

I scream, you scream, we all scream for LOBSTER!!!!

What is it about lobsters that people find so captivating?  Granted I will give you they are great drowned in butter or served with a side of onion rings.

Yumm! Lobster roll!

This past summer I spent working on a lobster boat. Now the cool thing about this lobster boat is we are built to all of the same specifications as a commercial lobster boat with three exceptions the biggest one being we carry passengers and give tours which focus on lobsters and the local area.

Before people even get on the boat they excitedly as "Hey, are we going to hold a lobster?"  "You bet" was my standard answer. With a few exceptions every time we pull a lobster trap on to the boat there are lobsters inside waiting to be released and a few that were making their escape as we are pulling the trap out of the water. There are a number of escape hatches built into a lobster trap which allows small lobsters to escape and the lobsters can back out of the openings into the trap if they want to. Every so often there were lobsters which wandered in and due to their size couldn't always get back out.

Each of these lobsters weighs between 6-7 pounds a piece. 

If you are trying to get a sense of size for the lobsters in the above picture that is my size 9 boot in the picture and to get a sense of the size of the crusher claw of the lobster in the middle take a look at the picture below.

My hand next to a 6 pound lobsters claw.

Even with rubber bands on the claws if pass a 6-7 pound lobster around the boat for people to take pictures with many will shrink back in terror as if you are handing them a loaded hand grenade. Lobsters are a little like alligators in that their muscles work better in one direction than they do in another. Lobsters have a great amount of crushing power in the crusher claw, about 100 pounds per square inch of pressure. However, you can free your arm or finger from a lobsters claw just by placing a screwdriver in the claw and twisting. I learned this maneuver by accidentally getting three different parts of my right arm stuck in various lobsters over the summer. To answer your question no broken bones, but yes it is a pain you will remember forever.

People would ask me what is the coolest thing about lobsters I knew and questions that at the time I didn't have any answers to. 

Top 5 cool facts about lobsters:
           
             1) Lobsters can regenerate all lost body parts with the exception of one. Lobsters can not regenerate lost eyes. If a lobster were to loose an eye a different body part will regenerate in the eye socket. This means there might be a four clawed lobster roaming the deep dark waters of the of the North Atlantic Ocean.

            2) Lobsters pee out between their eyes. As lobsters fight they pee in the face of their attacker.
Even though lobsters do not have a true brain, it is more a small collection of nerve endings, they can remember the smell of  a lobster they have done battle with for close to a week.

            3) The largest lobster ever caught off the North American coast was caught in Nova Scotia back in 1977 and it was 44 pounds and estimated to be 100 years old.  The amount of force in the crusher claw of that lobster can crush the bone on a humans arm.

            4) Lobsters come in a variety of colors and can be two different colors at the same time. When you cook these crazy colored lobsters they all turn red in the end.

            5) 80% of a Maine Lobsters diet is made up of lobster bait.

Answers to some of the most perplexing tourist questions:

            1) How far does a lobster migrate?  When the ocean begins to cool down they start moving to the deeper warmer waters. Most lobsters travel about a mile from where they send the summer and the deeper waters in the winter. Some may travel about 5-6 miles in search of warmer deeper waters. There was one lobster which had been tagged and then dropped in the waters off the Continental Shelf which was later recovered off of Port Jefferson, New York. That is a traveling distance of 225 miles!

           2) Why don't people farm raise lobsters?  Simple answer way too expensive. There are a few research institutions which will collect eggs from pregnant females and hatch them in an aquarium.

The back balls are lobster eggs attached to a female.

Once they get to about one inch in length before they are released into the ocean where they will settle to the bottom of the ocean and hide in crevasses in the rocks continuing to grow. On average it takes 6-7 years before a lobster gets to the minimum marketable size for a legal lobster here in the state of Maine. So if you were to try to farm raise a lobster you would have to feed them, keep them well oxygenated, and from killing each other for 6-7 years that is a lot of time and money. That would produce a very expensive lobster!

          3) How many women are lobstermen? First yes, the correct term is lobsterman not lobsterwoman, they will correct you. about 4% of lobstermen in Maine are women. this number does not factor in the number of women who work as sternmen on a lobster boat.

         4) What is the white slimy stuff you find on the top of lobster meat? This one took me a while to figure out what white stuff people were referring to. Some of the white stuff you find on lobster meat is nothing more than a connective membrane just under the lobsters shell and there is also a little bit of fat. When lobsters are cooked their blood which is normally clear turns kinda white and gelatinous.

         5) How much of the weight of a lobster is the weight of its shell? This one the answer is proving to be a little more elusive. Right now I have not been able to sleuth out that answer. Next time I will get my lobster to go and bring it home and pull the  shell off my lobster and weigh the edible parts and the shell separately. Stay tuned!
   

Well Played Pantoufle!! Well Played!!!

I am a live and live kind of person when it comes to animals. I accept that each animal plays it own role in keeping our environment on the level and all systems working.....that was before Pantoufle moved in under the apartment floor.

I took to calling my new unwelcome friend Pantoufle because I like the way the French word rolls off the tongue and I'm still a fan of the movie Chocolat . The word also sounds a little like poof which is what Pantoufle apparently does a lot of before he/she come home to spend the night sleeping under my living room floor.  So, what is Pantoufle you ask? Meet my unwelcome house guest.

Yep, I am the proud winner of a skunk under the floor. Pantoufle using its great powers of excavation has dug a hole under the neighbor's fence and the a hole big enough to crawl into the crawl space underneath my apartment floor.

I am no stranger to skunks in fact I spent part of the summer of 1998 living on an island in Boston Harbor which had quite the large population of skunks on it. During the two times of the year when the tide is the lowest they swim the short six foot span from mainland to the island and then become trapped out there when the tide comes back in. All the visitors to the island as well as those camping overnight always asked; "So, how many times have you been sprayed?" The answer to that question was never. Skunks give you many opportunities to evade them before they unleash the funk. Three warnings before you get the stink:
Warning #1 The grumpy Old Man: Skunks will make this grumbling chattering noise as they walk around. Think person mumbling underneath their breath.
Warning #2 Foot Stomp: Skunks will hop up and down on their front feet making it look as if they are stomping on the ground.
Warning #3 False Tail Flick: The skunk will turn its butt towards you and and flick its tail without unleashing any smell.

If you ignore all of these warnings prepare for the funk!!! If the skunk unleashes all of its funk at once then your safe for about a week as they remake more funk for the next unsuspecting victim.

Back to Pantoufle it moved in under the floor giving my apartment a odoriferous smell. The local game wardens set a catch and release trap in front of it's hole and the wait commenced. A week went by and no skunk was captured. Then one early Saturday morning while I was at work the Game Warden called with good and bad news! The skunk had been captured and sadly had unleashed all of it's skunky smell as the warden removed the cage from between the house and the fence. I came home to a smell that was so bad I swear I could taste it. GROSS!! Ack, what the (blank) do I do now. I threw the windows open placed the fans in the window trying to draw the smell out. Four hours later it was no better. I took a drive so I didn't have to smell it. I read online before I left that wintergreen oil would neutralize skunk smell. Ok, where do you find that!? Making a stop at a local chocolate shop I asked if they had any clue where I could find wintergreen oil? Local co-op they suggested. So, after purchasing some awesome chocolate I stopped by the co-op and yeah wintergreen oil!!!

Holding my breath I went back to the apartment and dipped a cotton ball into the oil and placed them around the apartment and waited.  Two hours later there was just a faint hint of skunk, but not the gut wrenching skunk in your face smell.  Thank-you random internet site for clearing out the smell.      

I ate a bug and I liked it. Taste like a sack of boogers.

Lately there have been a lot of really super awesomely cool articles on bugs in the news over the last month.  And recently there have been a lot of screaming people near me making it seem like the half dead bug dragging its way across the counter is carrying sticks of plutonium on each on of its legs.

Ok, I'll grant you some "bugs" can be a little scary. The reaction to most of the people I know to the video from Australia of a hunts man spider carrying away a mouse was something close to what you would get from watching the Texas Chainsaw Massacre. Check out the video if you haven't already seen it.

But some bug news was just sooo cool. Like hello, there are bumble bees in Northern Alaska!! Also because it is that time of year where people pull out their trusty Farmer's Almanac and attempt to predict the coming winter some people decided to try to figure out just how accurate everyone's favorite insect prognosticators are at predicting upcoming winter.

Bugs are cool there are so many reasons to love bugs and heck if all else fails they are tasty. I know I've eaten them....more than once.  We all have....deal with it. While I was working for an entomology museum we were getting ready for out annual bug fair and one of the things you could do is eat a wax worm taco or try some chocolate covered crickets. Fist we had to remove all the wax worms from the dry oatmeal they came packaged in. After a few minutes one of  the graduate student who was helping me started to freak out about having to touch bugs! I looked at her dead in the eye reached into the box and pop a wax worm into my mouth and started to chew.

Wax Worm about 1 inch long. Larval form of a moth.

 Immediately she threw her hand over her mouth and ran away flailing the other hand.  The other graduate student sat there wide eyed and stunned before asking; "what did it taste like?"  I though for a minute and said "tasteless Jello with the consistency of boogers." I dusted off one and handed it to him and after a few minutes of hesitation chomped down on the wiggly bug.  He just shrugged his shoulders and went on sorting.

Many cultures around the globe eat insect as part of the diet, yet here in the United States we get freaked out by the mere thought of knowingly eating a bugs. Sending us into gut wrenching dry heaves.

Whole books have been written about cultures and the uses of insects as food. My favorite bug food book is:

But really what is the big deal? Some spices and a little cheese and it's just like any other protein right? Regardless of if we want to believe it or not there is some bugs or bug parts in just about everything we eat. The FDA (Food and Drug Administration) even sets limits on how much unavoidable bug bits can be in our food. It's no big deal most of it is so small and chopped up you can't find it or see it without the aid of a microscope.

Add to your bucket list eat some bugs! Search out some place cooking and serving up some bugs. After all you have been eating spiders in your sleep your whole life with no complaints.

Your elementary school science teacher lied to you!

The other day I went for a walk along my favorite coastal Maine trail and heard a recurring comment from many hikers I passed; "It's too bad there are so many pine trees that are dying." There were a number of theories purposed as to why there is this great die off of trees which ranged from: "I guess they can't handle the salt water" to "they must have that bug like we do back home."

As I walked I tried to figure out just why people kept thinking that the pine trees were dying. Then it dawned on me as children we are taught, by well meaning elementary school teachers, there are two types of trees deciduous trees which loose there leaves every fall and evergreens which keep their leaves (pine needles) year round. However, most teachers fail to tell us that even though evergreens keep their needles year round they do in fact loose 50% of their needles each fall leading to that thick carpet of dead pine needles under every pine tree each fall. To conserve resources pine trees do in fact loose their needles. Once the lost 50% regrow in the spring the tree will loose the other 50% of its needles and begin to regrow them. So each year pine trees loose and regrow all of their needles.

Plus this time of year the tamarack trees put on one heck of a show by turning a yellowish gold and dropping all of their needles at once. Tamaracks are the only truly deciduous pine trees in North America.

Have no fear they pine trees are not dying they are merely getting ready for winter. Get out there and see of you can find some tamarack trees in your neighborhood.

Love is in the air.....

I was watching a nature related show a few months ago on PBS and it got me to thinking about ways animals attract a mate and help to ensure the survival of their species.

Each year while I worked in Yellowstone National Park I would indulge in some wildlife voyeurism starting with the bison in late July through September. Bison will chase, bellow/grunt (to hear some audio click here), headbutt other males, and try to push the object of their desire as far away from other males as possible. They even go so far as putting on some "cologne" to make them selves smell more desirable.  This involve peeing on the ground and then rolling in it.

Wallowing Bison in Yellowstone National Park

Elk also spend a fair amount of time making themselves smell better to the opposite sex and they also grow these massive antlers which do nothing but scream look at me look at me.

Me and My Elk Rack

Heck even the little peacock spider has a flash dance to attract a mate. It really is quite impressive and if you have never seen it you need to check out this video. How can anyone say no to dancing spiders?

I feel however there is one animal who gets a bum deal when it comes to ways to attract a mate. The musk deer.

They are primitive deer (family Moschidae) and unlike white-tailed or mule deer (family Cervidae) musk deer do not have big flashy antlers which scream look at me look at me. They have fangs which can go up to about four inches long over the course of the animals life. They are used much in the same way elk or other deer use antlers to fight off other males during the breeding season. Talk about some close quarter combat! Sadly these deer are endangered in much other their natural habitat due to poaching. The musk glands are prized by perfume makers and also used in Asian medicines. A quick search of the internet found the price can be as high as, well lets just say it is way more then I make in a years time. Sadly the commercial uses of the musk glands may lead to their eventual extinction.
