Frog Calls on your Calendar

Question:

Do I need to be submitting data now in January even though the frogs aren't out of hibernation? Do I continue recording data through just the breeding season (as long as I hear frogs calling) or through the entire summer? Thanks!

Answer:

Thank you so much for your question... it is a great one! Depending on where you live in the country, you will probably start hearing some species of frogs and toads pretty early in the spring. And then some species have breeding seasons that last throughout the summer.

In Maryland for example, Frogwatch USA volunteers can learn the species calls gradually by starting with those species that will call during the early spring period like the wood frog, followed by those species that begin calling in late spring like the green treefrog, and finally by those species that begin to call during the summer like the green frog. The chart below shows some of the species found in Maryland and when they typically call during the year. You can make a chart for the species in your state by consulting a field guide for more information about each species.
