After we installed the pond in front of the Wildlife Center last year, new neighbors are moving in! Varieties of frogs are checking the place out, and some are definitely calling 1800 South Delphine “home.”
In recent weeks, more than 100 tadpoles have been seen sunning themselves in the warm afternoon waters of the pond’s edge. Who are the parents? It’s hard to say because a Green Frog, a Pickerel Frog, and a Gray Treefrog have all been seen in the vicinity! And, earlier this spring, director of outreach Amanda rescued an American Toad out of Maggie the Peregrine Falcon’s enclosure and relocated it to the front garden, before Maggie could claim it as a snack.
Fish and frogs in this pond are an essential component of the ecosystem for keeping the mosquito population in check and for controlling the algae that develops in the pond.
The Wildlife Center does not frequently admit amphibian patients. Since 2011, we have admitted 25 frogs and toads as patients:
- 10 American Toads, Anaxyrus americanus
- 4 Bullfrogs, Lithobates catesbeianus
- 8 Green Frogs, Lithobates clamitans
- 2 Gray Treefrogs, Hyla versicolor
- 1 California Treefrog, Pseudacris cadaverina
These patients have come to us for a variety of reasons, including dog and cat attacks, lawn mower encounters, entrapment in pools, and other unknown causes.
If you are interested in learning more about frogs and toads, the Virginia Department of Game and Inland Fisheries puts out a wonderful booklet and CD set to help you identify frogs by sight and by their nighttime calls. Identifying frogs by their calls is easier than identifying birds calls because 1) there are far fewer species to be familiar with and 2) the calls are very unique. Also, visual and auditory identification is available through the Virginia Herpetological Society’s website.
If you have frogs in your area and want to help scientists learn more about these fascinating species, you can do citizen science volunteering through a couple of different frog programs: FrogWatch USA or the North American Amphibian Monitoring Protocol.
I started volunteering with FrogWatch this year. I have a marsh in front of my house, so I can report what I'm hearing by monitoring twice a week for five minutes. Of the 11 species that are in this part of the state, I've already heard four this spring!
