What Shat That Scat?

Yesterday our Wildlife Society Club visited one (we have two!) of our field stations, the East Hill Campus in Naples, NY. The point of the trip was to allow students to learn how to use camera traps, specifically the Cuddeback Captures, both IR and incandescent. We dragged along our local camera-trap expert, Dr. JVN.



We had a gorgeous day, there was a slight threat of rain, but it held off! I love this place, I really do. It came into official possession of the college's in the summer of 2010, right as I was coming into the fold at FLCC. The man who donated the land, facilities and assets is with us still, and I've been able to forge a nice relationship with him. He is truly and "old school" conservationist who has lived through the hard times of war, economics, politics, and ecological "stuff". I guess I can say that I am living those hardships as well, but he's of the era that we're learning about now in the classroom.

This property is the perfect representation of land that can be managed and used for multi-purposes...blissfully. He's owned the land for 25 years and shortly after buying it, he constructed hiking and cross country skiing trails, a campground with an A-frame, lean-to, fire pits, and newly added: an outdoor classroom as of last summer! There is a pine plantation, grassy fields, ponds, and all of it is ours :) Oh, did I mention that it's OPEN to the public? Year round? For FREE? His trails can connect you with the Finger Lakes Trail system, and eventually to the Appalachian Trail. So, Mr. Fraley- thank you for the outdoor classroom, generosity, and the laughs (at my expense)!


Now, back to our fun yesterday afternoon!

We had 9 cameras to set out, 7 students, and John...so I got to pick two spots :) I've been so focused on being precise and neat and tidy with setting my cameras lately, since I've been conducting a mini independent study with them, so it was really fun to pick camera sites that "looked good" and set the scent willy-nilly flinging it everywhere or shoving in a hole in the ground.

Judi and Adam set a camera in the background, and are now digging a little "cat hole" to stick the scent in. I took the New York State Trapper Education course this weekend, and am now certified to live trap, if I get my license. I took the course to learn about how trappers draw the animals in to their sets, because I'm pretty much doing the same with my cameras. So it was suggested to dig a hole and put the scent or bait in there to make the animal work a bit more for it. In their case, they want the animal to dance around and step in the trap. In my case, I want their cute little picture :) !!!

Next Dana and John chose this spot because it's a cross of trails. There's a trail coming in from the woods opening out to the mowed lawn we were standing on, so we thought it was a nice travel corridor to set a camera on.

John and Dana checking out the site :)

And here is where I got this entry's hilarious title. I found so many good scats that day! This happens to have been left by a Wild Turkey. I narrowed it down to Ruffed Grouse or Turkey...and was learned on the differences between them. Basically- this is a bit too big for RG.

Next on the list...who shat that? This is from one of our beloved foxes. Immediately I say red fox because that's who I have the most experience with. Until several weeks ago, I'd never seen one, and THAT was in North Carolina (the gray literally walked up to me as I was setting the camera). But, I asked, and John confirmed that YES there's probably an overlap in: size of scat, composition, habitat and so it could belong to a gray, but more likely a red.

On our way up the hill, we found a den or burrow that looked fresh-ish. There wasn't any fresh soil disturbed, but it wasn't completely closed in and plugged up with dead leaves and debris either. John's on this woodchuck kick right now (Woodchuck Love) so he was eager to set a camera on the entrance.

Adam, Judi, John and Dana...anyone home?

Kara setting an IR camera on a chunk of wood close to the entrance. I can't remember if we scented this site or not, but I think not. We wanted to see 'au naturel' activity here..if any.

Further up the hill we found this cool pine tree that was clinging to the top soil with all the strength it had. Again, all of us looking for a "cool" spot, were drawn to this little hidey-hole that some animal may live in, or at least come in to check out. So, Tyler set a camera.

Tree hugger gone too far? I think he's trying to grab the strap from around the tree, while holding the camera in place...

Now THIS scat...this is special scat. We, on good faith, know this belonged to a Mustelid, or loosely: a weasel. The tell-tale shape, twistiness, and composition of hair and little bones screamed weasel to us. When I say weasel, I kind of refer generally to all of those that are from the weasel family in NY. In this area and habitat, we could have: fisher (rare), mink, long-tail, short-tail, and the least (rare). We also have river otter and marten in NY, but not in this region or habitat. So, John thought that this was perhaps a little too small for mink, so maybe I filled in, a long-tailed weasel. Again, with the foxes, there's so much overlap. It's hard to tell.

Same scat again. To describe the habitat, we were in a pine plantation, and this scat (and the one below) was specifically on the berm of a small fire pond. Well, this year I guess we should call it a vernal pool- it was SO low and it's only the beginning of April!

A different scat, but perhaps a little more fresh. It was small, twisty...weasel-y.

Second scat again.

Dana and Adam are setting a camera to get the weasel. The pond berm is to my right in the picture, and in the picture below...

I'm standing on the berm, the pond to my left. Usually that pond is up to the lip of the berm. Not so much this spring...poor salamanders and frogs!

I convinced everyone to stop for a minute so I could set up and get a picture. That's the past yearbook editor and future mom in me. I like to include everyone! Especially now that I'm blogging!

On our way back down the hill, a final shat of the day. This is a beautiful coyote scat! Sorry for the lack of scale, but the pine cones are 4"-6" long.

It was just full of hair, and John explained to us that usually when you find a scat full of hair, it can mean that the animal was just picking a carcass clean. First choice at a fresh kill would be the meaty parts, but later in the season, or a late comer to the party is left with the hairy, boney parts. And that's what I found while pulling this apart- lots of hair and bone fragments.


I LOVE learning about scat, it's almost as cool as the remote cameras to me. Like the cameras, I don't have to 'be there' to learn all this information about the animal. I can come across it later and either look at the pictures, or examine the scat to get an understanding of foods, behaviors, habitats, etc etc etc. And scat is often NOT smelly (although I've heard raccoon scat should be handled with care), and not really gross. Just a lot of cellulose or keratin that the animal can't digest.


Anyway, we'll be letting our cameras soak for two weeks, and then hopefully I'll have all kinds of majestic creatures to share!

Winter Wildlife Tracking with Nick and Valerie Wisniewski

Another fantastic wildlife adventure: complete!

Through the club I am President of, The Wildlife Society Student Chapter at FLCC, I was able to arrange a tracking weekend workshop, and hire 2 lovely people from Walnut Hill Tracking and Nature Center (Orange, MA). I met the Wisniewski's last summer when I traveled to them with my Black Bear Management class that I was enrolled in last summer. We were studying this interesting type of marking behavior that black bears do, and these people are some of the only experts that I've been able to find.


For more info on this bear behavior: Back to bloggin'...for now.
Anyway, I loved learning from them last summer, so I decided to see if they could come visit us at our Muller Field Station for the weekend. I invited club members and other conservation department students, and some staff members for the experience.

Friday afternoon, Sasha (our advisor and my friend) met Nick and Val at the field station to give them the tour and get them settled in. We left them to explore for the night, and returned the next morning. We had a GREAT group of people that all came together for the weekend, and who were all very enthusiastic. I was thankful for this because I didn't want people showing up for a free 'weekend away' and to not take it seriously! This was far from the case. Students involved were: Myself, Kelly, Kasey, Leslie, Judi, Petra, Deanna, Sean, Marshall, Tyler, Dakota - - and staff members: Sasha (advisor, conservation technician), and Nadia (Muller K12 outreach coordinator).

We learned about track patterns, stride, straddle, track shapes, pads, negative space, other things to look for like nails/fur on the track, gait names, and how to measure all of those wonderful things! Nick and Val were teaching to us on a basic level, because although we had differing degrees of knowledge/experience about wildlife, we were still ALL basic trackers. It's a huge, wide field of knowledge and takes a long time to learn!

Unfortunately I don't have pictures of all the species tracks we identified, but I will list them off:
  • Red fox
  • Canadian Goose
  • Short-tailed weasel
  • Long-tailed weasel
  • Vole sp.
  • Mice sp.
  • Red squirrel
  • Gray squirrel
  • Possibly flying squirrel sp.
  • Mink
  • White-tailed deer
  • Raccoon
Other types of sign ID'd:
  • Deer bed
  • Deer rub
  • Red fox scenting
  • Bird nests
  • Vole tunnels
  • Mink slide
  • Coyote scat
  • Deer scat
  • Deer browse
  • Chewed walnuts
  • Squirrel bites
  • Woodpecker holes
  • Woodchuck hole
  • Dreys
  • Otter latrine site
Live sightings:
  • Canadian Geese
  • Mallards
  • Red squirrel
  • Gray squirrel
  • Blue Jay
  • Downy/Hairy Woodpecker
Our field station, was beautiful this weekend. On Friday night, it started snowing. Here in the NE and in NY, we've had little snow this season. But, it started likely flurrying as we were getting Nick and Val settled in. By Saturday morning it was a beautiful, snowy landscape.

Myself, taking in WINTER!

The following are pictures taken over the weekend, I'll try to ID everything. It's difficult now a day or two later, and I don't have items for scale in hardly any of the pictures or labels. We were really moving on the fly! And I didn't want to get in anyone else's way. I will try to include at least one fun fact I learned about each species mentioned.

Meet and greet outside the house!

First find of the day! Deer scat.

Frosty little jelly beans. Deer scat morphs with the season or even daily with what the deer are feeding on. Currently, in the winter, deer are browsing on tough, woody vegetation. Their scats are hard, compact little pellets, as you can see in this picture.

Next find: short-tail weasel tracks. Weasels are bounders!


As you can see, there are only 2 holes in the snow. That's because the back feet land where the front feet were previously.

Checking out some mink tracks! You can't see them in this picture, but they are running right along the line of ice and snow, on the snow.

Bounding along!

Activity around a plunge hole. Mink are semi-aquatic Mustelids, and they are well insulated against the cold air temps AND water temps.

Travel between docks. You can see one in the picture, and I'm standing on the other.

Behind me, on the other side of the dock, was a bank covered in long grasses and weeds, all bent over from the snow. This makes the PERFECT cover for small critters. In this picture is a hole in the snow that the mink created. Perhaps going after prey? Or just to go somewhere else...?

Beaver chewed speckled alder.

Nick using calipers on some Canid scat. Unable to identify it, but narrowed it down between red fox and coyote. Both have scat diameter ranges that overlap eachother, so it's hard to tell. But definetely a wild dog left this scat behind. What's interesting about this, is that those stalks of milkweed you see, I left out back in January as a marker for a live trap I had set out during my Winter Ecology course. About a week and a half-2 weeks after, I went back to the spot while on a walk, and found this scat on top. It's common for dogs, especially wild ones, to scent, urinate, scat on top of something (a hummock, downed limb, plants sticking up, trash). Does it help lift the scent? Is a visual marker? What are they trying to tell me? Get out? Or here I am?


Nick!

Canadian Goose tracks

Learning to measure straddle, or trail width.

Learning to measure stride, or length between tracks.

Valerie sniffing out some red fox urine. If you haven't smelled it before, and you live in red fox country- go outside. They're in mating mode right now, and the musk was almost thick on the air. We could smell it everywhere we went, and in my opinion, it's not an altogether unpleasant smell!

Everyone belly-down and sniffing for the scent spot on the red fox trail!

Dakota getting a sniff!

Leslie taking a turn...and...

Myself!

Here we found a squirrel midden in a rotted out black walnut.

Squirrels, particularly reds I think, are very territorial. They will create caches and middens at the center or core of their territory. As a part of that territorial behavior, they will often bite along a tree or branch. This is a visual marker as well as a chemical (they have scent glands in their mouths) marker that warns off other squirrels. The redder or fresher looking wood in this picture is the bite area.

A midden of walnut husks.

My beautiful roommate, Kasey, and I! Bundled up against the snow :)

Tons of little mice tracks. Not sure of species: Peromyscus or Mus.

Judi, our resident Brit, loving the snow!


And the last track picture I'll include are parallel track patterns of a white-tailed deer. I believe these are WTD because of the width of the trails. The deer on the left was dragging, most likely HIS, hooves. And the other, was picking them up out of the snow. If you look to the top of the picture, you can see the deer on the right begins to drag as well.
