Western Cottonmouth -
Agkistrodon piscivorus leucostoma
This big cottonmouth had just come out of the swamp and was heading towards the bluffs. Though it was fairly unwilling to gape, it did hold its head straight up in a very defense fashion. Not too far away, I spotted this very brightly colored juvenile near the edge of the swamp.
Western Cottonmouth - Agkistrodon piscivorus leucostoma
Finding cottonmouths in close proximity would be the common theme of the day as we ended up seeing more than fifty individuals on the road, near the swamp, and along the bluffs. We continued further down the road and saw a few more moccasins and the occasional green snake and ribbon snake. As we neared another swamp crossing, Chris spotted this pretty little Nerodia.
Yellowbelly Water Snake - Nerodia erythrogaster flavigaster
This would be the only species of water snake we would see on the weekend, with Mississippi Greens and Diamondbacks remaining elusive. The day rolled onward and provided plenty more of the usual suspects. We pumped into several herpers along the way who had mentioned they had seen timber rattlesnakes the day before in the late afternoon, yet despite our efforts walking high into the bluffs we had not seen the third species in the southern Illinois pitviper trifecta. As we were nearing the end of our day, I noticed on large bluff face was being hit by the sun really well and decided to go check it out.
Needless to say I was pretty excited when I spotted this juvenile timber make its way back toward the bluff wall. Timbers in the Midwest do not den in the large numbers that are often seen at den sites in the northeastern United States, so dens are a lot more difficult to locate and check. But I did see another timber at this exact same spot a few years ago.
Timber Rattlesnake - Crotalus horridus
Probably a yearling snake, this young horridus sported some very nice serrated chevrons, a dark post-ocular stripe, and a nice rusty dorsal stripe, all characteristic of timbers from the western part of the species' range. I didn't bother the snake too long for photos and after parting ways we called it a night. The next day brought some rather unfriendly weather. But earlier on in the morning, the sun was out and so we decided to spot hop a bit before heading to the road. Friday ended up being a great day for a species I didn't see last year or the previous day.
Black Rat Snakes - Pantherophis obsoletus
It was cool to see the transition that this species goes through in terms of appearance as they age from neonates to adults. The neonate was found along the bluffs amid a light rain in the mid afternoon. Earlier in the morning Chris and I cruised the sub-adult; which was about 2 feet long, along a rural road in the farm country. The nice adult was found scaling the bluff wall much later in the day during a heavy downpour. While a large group of herpers was photographing the black rat snake, part of the group moved farther up the bluff wall to stay dry and stepped precariously close to a known timber den. I was a bit surprised when someone in group yelled, "Timber!" I ran a short distance to see this adult timber poking its head out of its den.
Timber Rattlesnake - Crotalus horridus
This was the best photo I could manage before the rest of the group startled the snake back into its den. Based off the size of the head, the snake was probably in the three foot range. It's hard to know why it was thinking about coming out amid a heavy rain and temps in the low 50s, but I wasn't complaining. The inclement weather would cut the day shore, but Friday night was filled with lots of shenanigans around the campfire. It was great to catch up with people that I had herped literally all over the place and share a few drinks and laughs. Saturday would turn out to be one of the most interesting days I've ever had at snake road. Temperatures would only reach the mid 50s with scattered sun and clouds. Our first snake of the morning was this sharp cottonmouth on its way to its den.
Western Cottonmouth - Agkistrodon piscivorus leucostoma
Surprisingly cottonmouths would be in short supply on this day, with most being seen with their heads merely poking out of crevices in the bluffs. We decided to flip as many rocks as we could in hopes of seeing some of the fossorial species in the area. Not long after, someone in a group ahead of us flipped this beautiful little earth snake under a large rock.
Western Smooth Earthsnake - Virginia valeriae elegans
A secretive species, earth snakes spend much of their time burrowing underground in search of insects. They can occasionally be found under rocks and other sorts of cover in sloped environments. This individual was in great shape and a rather hefty individual for this species, probably 7-8 inches in length. We continued up the road and Colin Boguslawski flipped this beautiful ringneck snake near the north end.
Ringneck Snake -
Diadophis punctatus
Just like the copperheads from this region, ringneck snakes here also show a lot of phenotypic variation. Some individuals may have heavy spotting like the individual above, while others may have no spotting at all and appear to be like the northern subspecies (D. p. edwardsii). This individual was found in a large woodpile along with a few other individuals. As we headed back down the road, we got word that ahead of us a group had flipped a copperhead under a rock. We finally arrived to to a large group of herpers huddled around this little beauty which ended up being the rockstar of the weekend.
Copperhead - Agkistrodon contortrix
A truly gorgeous snake, this little fella had much more of a northern copperhead look to it than the individual that we flipped a few days earlier. Like other North American pitvipers, neonate copperheads exhibit a bright yellow tail which is used in caudal luring. We didn't bother this snake too much and then headed back town the road just in time for a member of our group to find this beautiful snake, one species I haven't seen at snake road since my first trip down.
Red Milk Snake - Lampropeltis triangulum syspila
A more colorful subspecies than the eastern milk snake, red milks retain this bright red coloration throughout adulthood. This neonate was found crawling along the bluff wall by Matt Boguslawski who was pretty bummed about missing out on the two timbers and copperheads earlier in the trip, I'm sure glad he managed to make this find. This snake also drew a large crowd and was the second most photographed snake of the weekend behind the neonate copperhead. A few more common things were found throughout the day, but nothing more exciting made an appearance in the cool weather conditions. We did stop by a few tin sites in the rain in hopes of finding some snakes taking cover, but all we found was a few of these pretty Plethodontids.
Northern Slimy Salamander - Plethodon glutinosus
The next morning took us to another well known site in hopes of finding a mudsnake and salamander species. While flipping some cover in some lowland areas of a cypress swamp, a few Ambystomatids turned up.
Spotted Salamander - Ambystoma maculatum
Marbled Salamander - Ambystoma opacum
One group did fine a Mole Salamander (Ambystoma talpoideum) but lost it before our group could get to them for photos. We headed further down the tracks, flipping cover along the way and one member of the large group pulled this monstrous racer out of some vegetation.
Racer - Coluber constrictor
Nearby, a small cottonmouth was flipped under a railroad tie and Daniel Dye's wife Yvonne called out that she had flipped a snake under a rock on a rocky hillside, but lost it. A group of us rushed over and began raking through the leaf litter and before long I saw a flash of red and pulled this little beauty out.
Midwest Worm Snake - Carphophis amoenus helenae
This small fossorial species is a personal favorite of mine, especially the individuals from this region of the country. Worm snakes here exhibit a chocolate brown dorsum with a bright pinkish-red ventral surface and are extremely attractive snakes. I spent a good amount of time photographing this snake before spending the next our or so flipping logs in the cypress swamp for mudsnakes to no avail. As we were walking the tracks on our way out, Chris Haas spotted this beautiful green snake basking on the ballast rock of the railroad embankment and was able to get it in hand for his lifer.
Rough Green Snake - Opheodrys aestivus
This snake was a great way to close a pretty awesome trip. We ended up seeing sixteen snake species on the trip and managed to completely the pitviper trifecta for second year in a row, though mudsnakes remained elusive once again. It was a fantastic weekend overall filled with lots of great field time and plenty of quality laughs around the campfire. I can only hope to once again attend a NAFHA meeting to catch up with everyone once again.
