The salamanders are moving

Between midterms, papers, and St. Patrick's Day festivities, I have made it out to the ponds a couple of times to see what amphibians were around.

The first night was warm, but dry, and I was a little worried that we wouldn't see good numbers of amphibians. Every vernal pond was completely ice-free and it wasn't long before we saw the first of many newts on the evening.

Every pond we checked had decent numbers of Spotted and Blue-spotted Salamanders, but there were only a few frogs. Spring Peepers were only sporadically calling, as were Wood Frogs. A few more days of warm weather, especially if we get a good deluge of rain, and there will be huge numbers of several species. Even still, we did get a few Wood Frogs.

We did find a big ole Bullfrog just hanging out on the trail. Bullfrogs aren't very common on the site - in fact I have seen less than 20 of them over the years.

Reuven made a great find with a Northern Brownsnake under a log. This was, by over two weeks, the earliest Brownsnake I have had at the site.

Of course, several first-of-year Green Frogs were swimming along the edges of the vernal ponds, and tadpoles, which take over a year to metamorphisize and spend the winter in the ponds, were also easy to find in the larger vernal ponds.

Matt found a snake as well - this time a Northern Ribbonsnake. While they are easy to find in the day, I have only ever found two before at night during the early spring.



The entire evening we were being serenaded by several owls, including 7+ Eastern Screech-owls and 1 Great Horned Owl. A few packs of coyotes howled in the distance, and lightning danced on the horizon though rain never did arrive. Several of the screech-owls came to check us out.

The following night was more of the same - same weather conditions and same species observed. I managed to photograph several Spring Peepers, including this individual. Unfortunately they were a bit camera-shy and wouldn't call while we were photographing them. As the spring wears on, their boldness will increase!

And finally, one of the many dozens of Spotted Salamanders that breed in these vernal ponds. We also saw a single male Four-toed Salamander crossing the trail (not photographed by me), the first of the year.

Coming up - I will be traveling to Point Pelee and area for a few days this week. Hoping for some record early spring migrants!
