Another Amphibian Night (7-Mar-2017)

With rain most of the day that continued into night, there was definitely going to be amphibians crossing the roads. I contacted Stephen Kloiber and Jon Mularczyk to see if they were going out to help cross amphibians. Both Stephen and Jon are bird enthusiasts, that at this time of year, hang up their binoculars to help amphibians get to their breeding pools safely. Both were going out and I arranged to meet them. Amphibians can be slow to cross roads and on nights when there are many crossing there can be high mortality rates. Often in areas where many amphibians cross you will find that there are volunteers that help move them across, lowering the mortality rates and helping to ensure we have these species around for years to come. For this and other reptile and amphibian posts, I am not giving a location as to where we were. It is illegal in the state to buy or sell native reptiles and amphibians, but just because there is a law doesn't mean that people don't do it. Not giving locations helps to protect these species from collection. Above is a female Spotted Salamander, one of the first finds of the night. At this time of year it is easy to distinguish male Spotteds from females. Males are slender with a large bulge at the base of the tail. Females are full of eggs and are quite large around the midsection. 

Spring Peepers are one of the smallest spring time amphibians. Only about the size of a nickel, they can be hard to spot in the road if they are not moving. Once they get to the breeding pools they create the loudest vocals, which at times can be deafening. Most of the time Spring Peepers can be identified by an X marking on their back. Not all individuals have this, but most do.

A male Spotted Salamander that made it to the yellow line on its own. If you come across amphibians crossing the road and want to help them along, first wet your hands, then move them in the direction they are heading and place them a couple feet off the road. The spring breeders like Spotted Salamanders, Wood Frogs and Spring Peepers know where their breeding pools are and will continue in that direction once moved. 

Spotted Salamanders are in the genus Ambytoma, the mole salamanders. They are called this because the majority of the year they are underground. Spring is really the only time they venture topside. Other mole salamanders in Eastern PA include the Jefferson and Marbled, the Marbled is a fall breeder and is not often seen other than the larval stage at this time of year.  

It is common to find salamanders crossing the road with this pose. I have no idea why they do it. 

A rarer sight crossing the roads are Jefferson Salamanders. Uncommon in the state this is a protected species. Generally Jeffersons breed earlier than Spotteds, but it really all depends on the conditions of the year. 

We only came across one Red-Spotted Newt on the roads. Generally they are a much more common sight. As juveniles Red-Spotted Newts are called Red Efts and are terrestrial. They spend over four years on land before returning to water and going through a metamorphosis into the adult stage. Both in color and structure the Red Efts differ from the adults. Above is a Red Eft. Adults are generally an olive color and the biggest physical difference the adults have is a large keeled tail.

Red-Spotted Newts are also trying to breed at this time of year. Either Steve or Jon spotted this adult Newt grabbing onto an unsuspecting Spotted Salamander that was passing by. It took some time, but the Spotted was able to break away from the Newts loving embrace.

In the ponds Spotted Salamanders congregate in certain areas. Males will deposit a spermataphore that will later be picked up by a female and used to fertilize her eggs. There is no contact necessary for this salamanders reproduction. 

Every once in awhile you will also find stream salamanders like this Two-lined crossing roads in rain events. They are not traveling to specific breeding sites, they are just crossing the road. 

Redback Salamanders can also be found crossing the roads on rainy nights. This species is fully terrestrial. Eggs are laid on land and when they hatch fully formed salamanders emerge. They have no aquatic life stage. 

A salamander that is often confused with a Redback is a Four-toed. Another protected species in PA, Four-toeds commonly cross roads during rain events. 

On this night I picked up at least one piece of trash at just about every stop we made to move salamanders across. Steve and Jon helped as well. Since we were just throwing it in the back of my car I didn't take a photo of everything at the end of the night. I hope you enjoy this post and watch out for amphibians while you are driving in the spring and summer! Thank you both, Steve and Jon, for your continued efforts in helping amphibians get to their breeding destinations!
