Update: Remains at a Deer Kill Site



It's great to have contacts. I finally sent the above photo to Charlotte over at the Adirondack Ecological Center to see if she knew what it was.

A quick recap: I found this brown ball of stuff at the site where a deer had been consumed by (probably) coyotes. My first thoughts were that it was part of the innards, but the fine texture reminded me more of fecal matter, albeit fecal matter from a domestic animal that eats processed food. As it turns out, I was both right and wrong with both guesses. Here's what Charlotte had to say:

"Your deer gut photo looks like the rumen...not the organ but what was in the rumen. Pretty typical for coyotes and what-have-you to not eat it. Pretty vile (or bile). We see that a lot around carcasses."

So, it wasn't an organ, but it was from the innards. It wasn't scat, but eventually it would've been once it was thoroughly processed.

And there you are!

Looking for More Signs of Spring?

Just in case you need a further dose of spring, hop on over to my gardening blog for some views of spring in Vermont - from my time at Merck Forest and Farmland Center. Just click here and enjoy!

More Signs of Spring

As I drove home from work yesterday, I watched two crows chasing and harrassing a raven. Every time they dove at it, it flipped over and presented its feet. Very cool. My camera was packed in my bag on the seat behind me, so no photos.

This morning, my boss came in and announced not only were the starlings back (she saw two at her feeders yesterday), but this morning she had red-winged blackbirds and grackles. I walked by her house about 8 AM today and didn't see or hear any blackbirds of any kind...must be they waited for the sun to warm things up a bit more.

Meanwhile, back in my yard, I discovered the following additional signs of spring late yesterday afternoon:


The giant pussy willows have emerged.



The black pussy willows have emerged.
These guys are stiff and bristly, not soft
and fuzzy like "normal" pussy willows.


The hazelnut catkins await real spring. Two of my four shrubs
have these male flowers this year. Maybe I'll get nuts this time around?


The apple trees have soft green tips, with what look like
new leaves at the very end.
I actually noticed these
a month or two ago...should've noted last fall when

the pussy willows popped if the apple trees had put out this new growth
at the same time. Will have to keep my eyes peeled better next fall/winter.




The rodents got beneath the snow and snuggled up around this burning bush, using it for fodder through the winter. This is why I wrap the bases of the trees and shrubs I want to protect. I don't mind too much that this shrub was attacked, for it is considered an invasive and is one of three more plants I need to remove from my gardens.

Spring?

I've been away the last few days. "Away" meaning I took time off from work. It was beautiful weather - I should've been out doing naturalist stuff. Instead, I did household stuff - cleaning, grocery shopping (a day-long event here in Newcomb because it requires a trip to Glens Falls), and reading. And even though the days were bright and sunny, with scads of blue sky and sunshine, the wind was bitter cold!!! Still, things have been melting. The roadsides are all covered with snert (or is it snirt?) - snow and dirt, or dirty snow. The snow away from the roadsides is alternately rotting and freezing. South-facing hillsides are bare. In other words, it looks like April out there, not early March.

This morning when I went out to fill the feeders (birds have been Spartan lately - even the blue jays are not wiping out the peanuts on a daily basis), I was shocked to see the following signs of spring:

1) Tulips, up almost two inches!



2) Daffodils up about an inch, pushing steadily through the leaves!



3) Azalea buds starting to swell and turn green!


4) The rhododendron leaves turning green!


At 8:30 AM, even Toby was lying down and soaking up some rays.



Even my 50 gallon "rain barrel", which collects the water dripping from my leaky gutters, was full of water. WATER. Not ice! After a clear night! The skim of ice on top was so thin it only took a gentle tap to shatter it. It's been full of mostly ice for weeks.


It's just too early for these signs of spring. Either we are going to have spring really really early this year, or we will get dumped on and all these plants will be sorry they put in an appearance so soon in the season.


When I got to work, I noticed that another warm weather creature had been out and about:



This is the remains of the bag of solidified bacon grease I had at the feeders. Remember the raccoon from my last post? I'd give good odds that it (or one of its friends) finally discovered this high-energy snack a couple nights ago and made short work of it.

Our snow stick is down to about 12 inches. More sunny weather is predicted for this week. It sure seems like spring.

Early Morning Tracks

I was the first person in to work yesterday morning, and after two days of being closed, the only tracks on the driveway were those left by animals passing in the night. What a treat to see such beautiful clear footprints in the frozen slush.



Fox and raccoon - a nice combination.



I'm always delighted to see raccoon tracks. Around here, where the winters can be brutally cold at times, raccoons only come out when the weather turns mild. When we have a warm night (warm, of course, being a relative term) we pretty much know that the raccoons will be out and about.



Raccoon tracks are always so easy to identify: they look like tiny human hand prints. Five toes, front and back. And when they walk, they place a hind foot next to a front foot, leaving a perfect impression of each, side-by-side.

This raccoon was headed toward the building, so I followed its tracks to see where it went. I suspected it was headed to the back deck and the suet (we bring the birdfeeders in at night, but the suet stays out). I was surprised to find the suet still in tact. It seems the raccoon had other things on its mind, for it made a beeline past the building and down the hill.


This is about the time of year raccoon mate, so we speculated that perhaps this was a male going in search of a female. Whatever its mission, it was nice to see its tracks.

Ancient Trees and Otter Antics

On Sunday last I joined a group of curious nature folks for an "Ancient Trees" hike with Vince Walsh of Kawing Crow Awareness Center in Greenfield, NY. I had blue sky and sunshine when I left Newcomb, but by the time I got down from the mountains, the sky had closed in and heavy wet snow was falling.

The first thing I noticed at Kawing Crow was this phoebe nest perched on the wing of Vince's emblem. It was a good sign for treasures to come.


After a short introduction, we donned our snowshoes and headed down the trail. Literally. The first part is about a 45' drop. Fortunately, Vince has installed ropes along the incline to facilitate our descent (and later the climb back up, which was actually a lot of fun).


Once we all made it down the hill, we forged out across the boardwalk Vince built across his swamp. What a great asset a boardwalk is to a wetland.




The wetland was so still.




Our first track of the day was this otter slide, leading towards the north end of Vince's swamp.




Here's the footprint inside the slide. I was able to count five toes and could almost picture webbing between the toes. This otter was to take up a good deal of our time as the day progressed. We tracked it until we found where it disappeared under the ice at a third swamp about three hours hence.




To me, this tree was one of the most interesting finds of the day. According to Vince, this damage was caused by the Sirex woodwasp, an invasive species that is wreaking havoc on our native pines, firs and spruces. [Update: I did a little research on Sirex noctilio (including an email exchange with two Sirex entomologists), and what I discovered tells me that this is not Sirex damage. The Sirex woodwasp primarily attacks pine trees, although spruces and firs are sometimes targets as well. This is a maple. Hardwoods are not on the menu. I will follow up some time in the future with a post about this invasive wasp, what to look for, and what our prognosis is with regards to its arrival. Based on other information Vince shared with our group about this patch of forest, I'd be willing to hazard a guess that this tree initially suffered from some sort of logging trauma (skidder damage, perhaps?), which provided the opening insects and fungi (et al) needed to begin their own invasions of this host tree.]


The otter reappeared at this stream. You can see where it came up the stream bed, through the slush, then out along the shore.



As we made our way through the woods, we passed this wigwam that Vince made with some kids last summer. Wigwams are the type of house the native people in the northeast used. Teepees were strictly a plains Indian dwelling.




Here's a close up of the wigwam. These houses are made by first creating a framework of bent saplings. Then the outside is covered with slabs of bark. Elm is the best bark for this outer layer, but these days not readily available.



The second swamp we encountered was dotted with great blue heron nests. Vince said he's counted upwards of 40 nests in this swamp. Such nesting collectives are referred to as rookeries.



It was a perfect day for snowfleas! From the moment we started our trek, snowfleas kept us company. In the woods, out in the swamps, the "fleas" were everywhere! As noted in previous posts, snowfleas are very primitive creatures, and are technically springtails, not fleas. They are quite tiny and look like pepperflakes sprinkled on top of the snow. I was able to capture these two with my macro lens.



We made our way carefully across the snowy top of a beaver dam. We had to watch our step, for the snow hid many a hole where the unwary snowshoer could (and did) fall through. Fortunately, it was usually just one foot that went down, not the whole snowshoer.



There were lots of mink tracks to either side of the beaver dam. Here we have a pair of slides, one next to the other. Was it the same animal, or were there two?


Here you can see the mink's feet, side-by-side, in the bottom of its slide.



These closely spaced tracks led away from the beaver dam and towards the shore. They didn't look like any tracks we'd seen before, so we wondered whose they were.



The tracks came down to another bit of open water, went in and came back out. But in the shallow water, there was another clue to the identity of this animal.



Vince scooped up something on a stick and passed it around for us to sniff. Hm...smelled kinda fishy to me. It was otter scat.


In case you are dying to know what otter scat looks like, here it is. It is often a rather formless mess, thanks to the fishy diet these animals consume.


We sort of followed the otter from the swamp, and re-encountered it as is slid down this stream bed. It really seemed to be enjoying itself here - lots of sliding with only the occasional push of the feet.


After we crossed this little stream, we found a small pool that was still open. The otter(s) found it, too. Note all the slides in and out. It was shortly after finding this that we crossed the stream again and I fell through. Well, one foot went through the ice and slush. Three cheers for wool and Gor-tex, for my foot did not get cold until the drive home. A bit later on, when we were looking at where the otter's tracks ended (it dove beneath the ice in a third swamp), I kept thinking I smelled something fishy...really close by. I looked at my hand, the one that went down when I crashed through, and noticed it had a brownish tinge. I sniffed. Fish. I must've placed it in some otter scat while struggling to extract myself from the stream. Ick.


It was after 3:00 when we reached our primary destination: the swamp with the Ancient Trees. These trees are black tupelos, or black gum (Nyssa sylvatica). Just how old is ancient? Well, some of these trees have been cored, and they range from 500 to 800 years old. That would be dating back to the 1500s, or even the 1200s. Long before Europeans set a toe on this continent.

Note the hole near the base of this tree.



One of my favorite tree books, and one that I use as a primary source for any tree research, is Donald Culross Peattie's A Natural History of Trees, written in 1950. Here's are a couple passages from his entry about tupelos:

“When to the amusement of Creole society, the tall and emaciated General Andrew Jackson leaped beside the short and immensely fat Mrs. Jackson, at a ball held after the battle of New Orleans, it was to the jig tune of “Possum up a Gum Tree.” The ‘possum, we may suppose, goes up the Gum tree in fall to get the fruit – or perhaps is merely treed there by hounds – but that does not make it clear why this species is called a Gum. Nowhere on the American continent has anyone ever expressed from this dry and disobliging vegetable one fluid ounce of any sort of gum. Yet lumbermen and foresters insist on the name.”

“To the Black Gum, as a timber tree, the pioneers said anathema with every abhorrence. For its fibers are not only interbraided but cross-woven. It is as easy to split across as lengthwise – that is, it can’t be done at all, even with wedge and sledge.”


The latter explains why these trees were allowed to grow to such a ripe old age: they are near impossible to cut. Therefore, they have little value to the lumberman.

Here's a peek inside the hollow opening near the base of the tree. Most tupelos are hollow, at least at the base. The trees, however, are still alive. This is because the living tissue of trees is the part that runs just below the bark, where the phloem and xylem transport food, water and nutrients up and down the tree. The bulk of the tree's trunk is dead wood, whose primarily purpose is to provide structural support to the branches up above.



Here is a shot looking straight up from inside the hollow. The tree is hollow for about six feet up.



Vince reached into the hollow and pulled out a handful of fine brown powder. This was decomposed porcupine poop. A few pellets still remained, but it has been a while since porkies used this particular den.


Digging through the snow at the base of the tree, Vince uncovered the remains of a porcupine scat pile. This is very typical outside porcupine dens.


Look at just how chunky that bark is! These are enormous plates, with crevices in between almost a finger-length deep.


Another characteristic of these ancient trees is that on one side, the heavy craggy bark is practically smooth. No one seems to know why this is. A couple of us speculated if it was because of animals travelling up and down this side of the tree, but it is only the oldest part of the tree (the base) that is "worn down." It remains a mystery.



As seen from a distance, the tupelos look like perfect Halloween trees - gnarly, twisted, and full of character. Apparently, these trees die from the top down, so many have abbreviated trunks with large branches reaching beyond the terminal end.



The fruits of the tupelo are called drupes. A drupe is "a more-or-less fleshy fruits with one compartment and one or more seeds" (Longman's Dictionary of Environmental Science). Examples are cherries, plums and other fruits that are considered "stone" fruits. A few tupelo fruits still clung to the branches.


I liked the burl on the side of this tupelo: it was basically a donut. I, unfortunately, am vertically challenged enough that you can only juuuust see the hole in the middle (it looks like a small layer of snow).


This old tupelo has seen better days. For some reason, the local beavers girdled the tree, and even gnawed the hard wood beneath. I wonder if tupelo dulls beaver teeth with its toughness? There was much discussion among the group about why beavers girdle the tupelos. Jackie sees this all along the Hudson where "her" tupelos are growing. Are the beavers just trying to open up the canopy? If so, why single out the tupelos? Vince suggested that somehow the beavers know that tupelos suck up a lot of water with their roots, so perhaps by girdling (and killing) the trees they are attempting to prevent water drawdown within their ponds.



This lovely orange jelly fungus was growing on the side of one of the tupelos. I love orange jellies, for they add a dash of color to the landscape.




We came across this really nifty witch's broom on a highbush blueberry. None of us had ever seen brooming on a blueberry, so this was a neat discovery. What causes the brooming? On some plants it is insects, on others bacteria or fungi. On blueberries? I have no idea...maybe someone out there has studied it and has an answer.





At the end of the day the sky cleared and the sun shone brightly. Heading back across the beaver dam, the swamp took on a different look than it had when all overcast. An hour or so later, as I pulled out the driveway and started the long drive home, the weather had changed once more, and rain started to sprinkle on the windshield. It was a long day, but well worth the adventure.
