Herping in Will County, Illinois

Blue-spotted Salamander: PC Tristan Schramer
Date:
April 4th 2015

Species Found:
  1. Spotted Salamander (Ambystoma maculatum)
  2. Blue-spotted Salamander (Ambystoma laterale)
  3. Western Chorus Frog (Pseudacris triseriata)
  4. Eastern Newt (Notophthalamus viridescens)
  5. Northern Green Frog (Lithobates clamitans melanota)

The Trip:

Tristan had herped in Will County before and found a lot of cool species that Noah and I had never seen. We decided to make a stop there after we were done helping with the mudpuppy research. We got there and started making our way toward the ponds. Deer were everywhere and what was weird was that these deer seemed to be more brave than the other deer I had seen. You could get as close as 10 meters to them before they ran away. We finally got to a pond and flipped a log by the water's edge. Surprisingly, 2 of the species we had come to find were sitting right there. A Spotted Salamander, which I had seen before, and a Blue-spotted Salamander, a new species for me. I was really excited to see my first Blue-spotted  but I was just as excited about the Spotted because it had orange spots on its head, a trait that I had never seen before.

We knew we would find more of these salamanders so we carried on without taking too many photos of these. The second log we flipped had a large gravid Spotted Salamander. It was the fattest salamander I had ever seen.

As we continued to look under logs, we found whole clumps of these salamanders, just crawling all over each other. We also found some salamanders living in the logs, under the bark.

We then settled down by a pond to photograph the salamanders. As pretty as they were, they were frustrating specimens to photograph. They just refused to sit still for longer than a second.

Some of the salamanders we found had some weird lumps on their throats and bellies. We weren't sure what this was but we knew it wasn't good news. We took pictures of the affected areas to forward to herpetologists so that they would be able to find out what was wrong.

The background music to all of this was the deafening sound of Chorus Frogs calling. A small log that I flipped had a small Chorus Frog under it.

We moved away from the small ponds and went to a large pond with lots of vegetation and algae in it. Tristan said that this would be a good place to find newts, an amphibian that I had never seen before. It took about 5 minutes for Tristan to catch a male Eastern Newt in his net. This was a new species for me so I took my time examining it. Its skin was much rougher than the skin of any salamander I had seen before. Newts are also known to be poisonous, but only when ingested. I had no plans of eating the newt so I was pretty safe. Tristan later caught a female with a large, fin-like tail.

Somehow Tristan managed to get pictures of the newt yawning. This was hilarious.

At some point we caught a tadpole of a Northern Green Frog. It looked a lot like the Bullfrog tadpoles I had seen before but the spots were different.

This trip was pretty successful. I got 2 new species to add to my American Herp List, which now stood at 48 species.

UPDATE:
We sent the photos of the diseased salamanders to herpetologists Chris Phillips and Andrew Kuhns and wildlife veterinarian Matt Allender. According to them, the lumps were formed by "yellow grub", a parasitic fluke that needs salamanders (or fish) to complete its life cycle. Here is the wikipedia excerpt:

Yellow grub require two intermediate hosts, usually a snail and a fish, but in vernal ponds salamanders are often infected, and one definitive host - birds.  If an infected salamander is ingested by a heron or other wading bird, the fluke matures in the throat of the bird, eggs are released through the birds feces, hopefully back into the water, and picked up on the foot of a snail, they then reproduce asexually and exit the snail foot as free swimming larvae in search of another fish or salamander to repeat the cycle.

It is unclear what effect this parasite has on the salamander's survival, but the disease is apparently quite widespread.

Spring Herping in Vermilion County, Illinois

Spotted Salamander: PC Yatin Kalki
Date:
March 15th 2015

Species Found
  1. Red Back Salamander (Plethodon cinereus)
  2. Spotted Salamander (Ambystoma maculatum)
  3. Silvery Salamander (Ambystoma platineum)
  4. Northern Spring Peeper (Pseudacris crucifer)
Background:
The snow had just about melted and signs of Spring were starting to show so we decided to go herping. Noah, Tristan and I went to Vermilion County on March 12th with a group of about 10 herpers from all around. We didn't expect to find any snakes but we hoped to get a few salamanders and frogs. On this trip we heard a few Chorus Frogs calling but we didn't find a single amphibian or reptile. We did, however do a lot of hiking and saw some amazing sights. There was a stream that cut through the preserve, with a pretty cool looking mini waterfall, where we found a dead coyote pup. We also saw a few wild turkey: 2 males and 1 female.

The next day we decided to go to Busey Woods, a small forest just off campus. We walked through the whole tract, wading through the ponds and flipping every log but we couldn't find anything there either.

The next couple of days were really warm so we decided to go back to Vermilion County and see if the amphibians had woken up yet.

The Trip:

We were greeted with the welcoming sound of Spring Peepers calling as we made our way up the trail leading to the forest. When I had come last October I had seen a fresh deer carcass in the middle of that trail. Now it was reduced to clean, white bones. We started flipping some of the logs on trail and under the third or fourth log we flipped, Tristan found a small Red Back Salamander. This was our first herp of the season so we were all way too excited about this small, super common salamander. (So common that we had seen close to 100 on one hillside last Fall). This also meant that the ground had thawed and the amphibians were awake. We were eager to find more cool herps.

We made our way into the forest and saw some neat ponds that the frogs and salamanders use for breeding. Noah and I set off herping in different directions while Tristan tried to net salamander larvae in the ponds. The area I was working was the exact same one I had worked in Fall, and sure enough, just like last Fall, I found nothing but earthworms and slugs. I headed back to the ponds to find Tristan and Noah taking photos of something on the ground. After failing to net any larvae, Tristan had found a Spotted Salamander under a large log near the pond. I had never seen this species before so I was very excited. The contrast between the dark body and the bright yellow spots was amazing. The Spotted Salamander was pretty large, around 17cm long. Seeing a salamander so big and beautiful made my day. Even if we didn't find anything else, I would have been happy.

While we were photographing the Spotted Salamander, Tristan told me that he really wanted to find a Silvery Salamander. There was supposed to be an isolated population of them here in Vermilion County, the only population in Illinois. This meant that they were an endangered species in the state. I told him that I'd be on the lookout for Silvery Salamanders, even though I didn't even know what they looked like. Since the area I had been searching before had given me nothing, I chose a new direction and went on looking under logs and rocks as I walked. I must have flipped over 200 objects because my body went into autopilot, lifting up a log, looking under it and replacing it. I was about 100 meters away from the pond when I saw a large black salamander under a small piece of wood. I had picked it up before I even realized that I had found a herp. I didn't know what species it was but it was fat, black and had some bluish marbling on its sides and belly. I called Tristan and Noah over to take a look. Tristan confirmed that it was a Silvery Salamander. This was a first time species for all 3 of us. The one I had found was a gravid female, in fact all members of this species are female. They reproduce by cloning themselves with the help of sperm from other salamander species. The foreign sperm doesn't contribute an genetic material but it activates the embryos into developing. Most Silvery Salamander populations use Blue Spotted Salamander sperm but this population uses Smallmouth Salamander sperm. It's kind of amazing that such a bizarre interaction exists in nature.

While Noah and Tristan were photographing the Silvery, I proceeded to keep searching the area I had found it in. Less than 5 minutes later, I found a little Spring Peeper under a log that was half immersed in a small puddle of water. I caught it and bought it back to the log by the pond where Noah and Tristan were photographing the Silvery. I set it down on the log and took a few pictures before it jumped into the leaf litter. When I chased after it I saw not 1 but 2 little frogs jumping through the leaves. The new Spring Peeper was yellow while the old one was gray. Both had the characteristic X mark on their backs, which gives them the name 'crucifer'. I had seen a Spring Peeper in Vermilion County last Fall but it was still nice to see the frog that was making so much noise in the forest.

It started to get dark and we decided to call it a day. We had planned to visit another spot where we had found Slimy Salamanders last time but we were satisfied with the herps we had managed to find already. With 2 new species to add to my list, I now had 39 American Herp Species. This successful herping trip is sure to be the first of many. I hope to continue to find cool herps throughout the year.
