Sunkhaze National Wildlife Refuge 1

On the weekend of May 18th and 19th, my herpetology class took a trip to Sunkhaze National Wildlife Refuge. We spent the night at a camping area nearby. Upon first arriving at the camping area, we were greeted by many eastern newts in the pond at the site. They were quite cute and proved fairly easy to collect once they were found. I didn't actually catch any, but I didn't mind. 




Once we had dropped off our belongings, we traveled to the refuge and spent the first part of the afternoon hunting for frogs. And we found many! There were green frogs, pickerel frogs, leopard frogs, and some wood frogs. I am not sure which frog is in the first photo below, but the second one shows a pickerel frog, which is similar in appearance to the northern leopard frog. The pickerel frog is more apt to have two organized rows of squarish spots, however. The third photo is that of a green frog with blue coloration. The bucket in the next picture is full of green frogs, while another green frog is pictured chilling in a pond and being held. It's ideal to hold a frog from their hind legs to prevent harming their soft bodies and to keep them from attempting to jump away. 







We spent the rest of the afternoon attempting to find snakes but only came across one eastern garter snake, which I did not get a good photo of. We left the area to return back to the camp area and spent the early evening relaxing before going out again that night to find more frogs. During the night outing, we found more green frogs and many bullfrogs. The frog in the picture below is a large male bullfrog, which can be discerned from the yellow throat and the large tympanum behind the eye. To tell the difference between green frogs and bullfrogs, you need to observe the dorso-lateral folds along the back, leading down from the eye. It continues almost completely down the length of a green frog while stopping short and curving behind the tympanum of a bullfrog. 

That outing ended the first day and led way to a very cold night spent in sleeping bags that did not offer hardly any warmth.

Tree Frogs of Maine

For the past ten weeks, I have been enrolled in a Herpetology class, exploring the lives of amphibians and reptiles worldwide. On Friday night, the class took a trip to find gray tree frogs, one of two tree frog species found in the state of Maine. We searched for them around a small pond and were happily greeted with a chorus of their calls. Some were on trees while others were perched along the moist bank. I managed to pick up two of them, but I much rather enjoyed watching their vocal sacs and many contracting muscles move as the trills to seek a mate continued. I took a picture of one while I held it, although it's not a very good photo, another of it on the ground, and I recorded part of the chorus. There were also many spring peepers calling, the smaller tree frog species in Maine, pictured in hand as well. It was a very satisfying night, in spite of the many bug bites I received all over my back.
