Do you know your amphibian egg masses?
Despite the snow, the internal clocks of many amphibians are already set to spring. As a result, a number of them have already journeyed from the safety of their winter refuges to nearby pools and ponds to breed and deposit their eggs. This past Friday, prior to the weekend storm, I spent time exploring some local water bodies and found a plethora of these kinds of eggs. Any idea of what these little eggs will eventually turn into? I’ll give you a hint, the bottom picture shows both eggs and spermatophores. If you guessed Spotted Salamander (Ambystoma maculatum), you would be correct!...

Our winter weather has been getting stranger by the day! This week we are going to see daytime temperatures in the mid 60’s and overnight temps in the low 40’s and 50’s with possible rain. And you know what that could mean right? Amphibians could potentially begin their migrations to their vernal breeding pools within the next few days! This time last year we were still buried in snow and were still experiencing some of the winds and weather from the “polar vortex.” Due to the extreme cold last year, it wasn’t until early April when we saw spotted...

Have you ever wondered what might be hiding just beneath the water’s surface in these temporary pools that crop up in early spring? This little clip reveals a productive vernal pool that has a number of spotted salamander (Ambystoma maculatum) egg masses nestled within the leaf litter of the pool floor. These pools are an important breeding area for several amphibian species, as you can see, because they provide a safe fish-less environment for the eggs and eventual tadpoles to...
Read MoreMale Competition
The Wood Frog (Rana sylvatica) is another early spring breeding amphibian common to our region. These explosive breeders utilize vernal pools, just like spotted salamanders, and their breeding activities are squeezed into just a few days. As the frogs enter the pools, males will take up their positions floating at the surface of the pool croaking their characteristic call. While they are calling, they will often joust with one another, especially if a female is nearby. These two males had a bit of a tousle, but both went on to call in another spot ready for females to come their way. Elyse...
Read MoreSpring Migrations Have Begun!
So I’ve got a bit of a funny story for you and it goes a little something like this: last Thursday night, as we suspected, warm overnight rains began to draw spotted salamanders (Ambystoma maculatum), spring peepers (Pseudacris crucifer), and other amphibians out from their winter refuges. They began their journeys to nearby vernal pools, but some of them took detours in the process. My husband Tyler and I were house and pet sitting for my parents while they were on vacation. Behind their home is a series of ponds that make up a beautiful wetland system, and vernal pools are abundant...
