A nice May outing

In May of 2009, I spent a day with herpetologist Dave Mifsud and his intern Max surveying a critical habitat type known as prairie fen. This fen exists on a lake margin and is home to several protected herp species in Michigan. Targets on this beautiful May day were the Eastern Massasauga Rattlesnake, Spotted Turtle, and Blanding's Turtle. Today was a real treat, as Jim Harding also joined us for the day. Jim is considered to be the "go-to" guy on Michigan herpetofauna. After brief introductions and conversation, we headed into the field.


Fen habitats that are intact as this one, are critically fragile and important in Michgan. Fens are considered to be a peatland, meaning that they are composed of tons of decaying plant matter. This decaying plant matter is very old and can be dated back thousands of years from when the glaciers receded, meaning nutrient recycling in these habitats is very slow, and therefore makes them very fragile to human disturbance (development, pollution, etc.) Late May is a tough time of year to survey these sites for species as the cover becomes very thick and makes it difficult to spot snakes and turtles, here's Jim and Dave traversing the area.


It took us awhile, but eventually we scored our first find of the day, a large gravid female Eastern Garter Snake. Dave is currently involved with some major projects in re-evaluating the distribution of Michigan herpetofauna and so even common species need to be documented at sites, we processed the snake and continued on our way.

Eastern Garter Snake - Thamnophis sirtalis

Another cool faunal component of peatlands such as this are species of carnivorous plants. The more common being the pitcher plant, and the less common being the sundew. We were able to come across a few sundew plants during the day, the biggest concentrations of them I've ever seen in the wild.


One of the highlights of the day came around mid-day as we were traversing the fen. Max and I were out near the edges of the property when Max called out, "Blue Racer!" Immediately I ran over to see a beautiful adult Blue Racer basking in the hazy sunlight. Blue Racers are a snake I don't often get to see in the field and it was a great sight indeed. Unfortunately, we only managed a few shots of the snake before in darted away into the thick cover.

Blue Racer - Coluber constrictor foxii

Finding the racer was a huge lift for morale, and we headed off site to check some side roads to see if anything was about. Unfortunately, the road bordering the site we had just been surveying produced this sad sight.


This large adult Eastern Massasuaga had clearly been hit earlier that morning or the afternoon before. However, we noticed that the rattle had been cut clean off with a knife or other sharp tool. It sickens me that some Michigan residents feel the need to hill this species of snake, as it poses no real harm to anyone if they leave it alone. Oh well, I guess whoever killed this snake has a cool souvenir for his trailer...Rednecks....

Anyway, we continued up the road and came across a much more encouraging sight!


This adult female Blanding's Turtle had been excavating right on the edge of the road. Blanding's Turtles and other Michigan turtle species have a bad knack of crossing roadways to nest or even nesting right on road enbankments. Jim picked up this girl and gently palpated her to find that she was still full of eggs. I had never palpated a turtle before, so it was cool to learn a lesson from Jim.



Blanding's Turtle - Emydoidea blandingii

It was a fantastic day despite the DOR massasauga, but overall we were able to document some cool species and enjoy each other's company. The Blanding's we found on the road warranted a few return trips from me which yielded more turtles excavating on the roadside, a reminder for Michigan residents to drive carefully during May and June.

Florida Rattlesnakes!

Back in June of 2009, I made a short weekend visit to Florida for a cousin's graduation party. Although the trip was not a herping trip, one can always find time to get a little field time regardless. Our flight arrived mid Thursday morning and by later that evening my cousin Robbie and I were out in a local state forest in central Florida. The temperatures were hot, but it didn't deter us from getting a little herping in. There's something about the Florida pinelands that I love, just a unique habitat.



Although the heat was manageable, the bugs were just dowright awful. As the sun began to get low in the late afternoon we decided to hit some roads that crossed through the forest to hopefully catch some snakes moving on the roads. As we were leaving from our pull off, I noticed something on the right side of the sand road and immediately stopped the car. Rob looked at me and asked, "What?" I looked back at him and tried to explain the small shape I had seen, "This is going to sound crazy, but I think I just saw a pigmy rattlesnake coming onto the road." Rob immediately jumped out of the car and ran back about 10 yards and began yellled for me. Sure enough...


Dusky Pigmy Rattlesnake - Sistrurus miliarius barbouri

I absolutely love these little rattlesnakes, and this was only the third I've ever seen, and the first in 2-3 years. his little guy was pretty jumpy and was filled with a little attitude, these cousins of the Massasauga have a much more agressive streak than their big cousins. We spent a few minutes with this cool rattler, and then headed out to hit a few more roads. We were excited to have found a pigmy on our first outing and the rest of the evening looked good. Not too much later on, we came across this massive DOR Yellow Rat Snake, a snake that has eluded me in Florida, the only ones I've ever seen have been DOR.



A little discouraged by the Yellow Rat, we pressed on. Our persistence paid off when we hit another sad road right at sundown. We looked ahead and saw what appeared to be a snake. However, when we jumped out of the car, it turned out to be my second ever Eastern Glass Lizard, love these guys.


Eastern Glass Lizard - Ophisaurus ventralis

As we left the forest heavy rains set in. Within a few hours, the Florida roads were littered with these guys. One of my favorite Anurans due to their funny looks and call.


Eastern Narrowmouth Toad - Gastrophryne carolinensis

The following day was filled with graduation festivities and left Saturday open for a day trip somewhere. We ended up heading north to one of the three National Forests in Florida. We arrived mid-morning and found ourselves in-between periods of rain and sunshine throughout the day. Our initial reaction to the Osceola National Forest was that its a place of natural beauty.



We spent the first hour or two driving around to explore the forest a little and get a feel for the environments found in the forest. We came across several DORs which included cottonmouths, racers, and a corn snake. On the outskirts of the forest, we stumbled across this abandoned property that looked particularly snaky.



Several discarded boards lay around the property and so we decided to flip around a little bit. Aside from a few skinks we turned up a few of these, no doubt Florida's most common snake.




Southern Black Racer - Coluber constrictor priapus

Later in the afternoon, some heavy rains moved through the forest. Fiften minutes of rain, half hour of sunshine, repeat. Thats the way the cycle went until the late evening. After a period of rain, these guys began to show up on the roads and even after dark. No trip to Florida would be complete without a few of these guys.







Florida Cottonmouths - Agkistrodon piscivorus conanti

The sole reason for us to venture to the northern section of Florida was the hopes of encountering a rattlesnake that neither of us had seen. Canebrake Rattlesnakes reach their southern range limit in northern Florida. After a few tips from Floridian Daniel Dye, we focused our driving on a few particular areas of the forest. Around 5:00 PM we rounded a large bend in the forest road, and looked ahead in the road and noticed a very serpentine shape coming on to the road. As we got closer we both yelled, "Canekbrake!"




Canebrake Rattlesnake - Crotalus horridus atricaudatus

It was one of the most beautiful snakes I've ever seen, and one of my favorite moments in the field I've ever had. We snapped photos for a few minutes, and let this gorgeous Crotalid on its way, a wonderful way to close another great trip to the great state of Florida.



Foxy

Before the beginning of the 2008 field season, I promised myself I would spend a little time looking for one of Michigan's largest snake species. The state is home to two subspecies of Fox snake; the Western Fox Snake inhabits the pine barrens of the western Upper Peninsula while the Eastern Fox Snake is found in the coastal marshes of the southeast Lower Peninsula. Not only is the Eastern Fox Snake a threatened species in Michigan, but its habitat is also one that is in need of constant management and protection. An invasive cattail known as Phragmites has choked much of these coastal marshes and outcompetes native cattails. However, some areas of coastal marsh are still in good shape and have native species still in control.



Fox snakes are one of the more attractive species in the state and their size makes them equally impressive. Several trips to the coastal marshes this summer produced severals snakes ranging from 2.5-5 feet. It was a privilege to be able to help a local herpetologist with his work on these snakes during the summer and is something I hope to do in the future.








Eastern Fox Snakes - Elaphe vulpina gloydi

Massasaugas from over the years...

The Eastern Massasauga Rattlesnake is Michigan's only species of venomous snake, and the Wolverine state is considered to be the stronghold for the species which is declining throughout its recognized range. In fact, its a is a candidate species for federal protection by the U.S. Fish & Wildlife Service and could be listed within the next few years. Ever since I got into herping a few years back, I've managed to compile quite a few field encounters with this species and have also kept a large photo collection of those encounters. So here's a big collection of photos of Massasaugas I've encountered over the years...
