Frog Call Recordings

Below are links to two separate frog choruses.

The first was made on the night of May 18, 2013 in Eastham, at woodland Vernal Pond E09. It contains four species of frogs calling. The loudest and most conspicuous is the grey treefrog, a species that most people are not familiar with. It calls occasionally from woodland vernal ponds on warm nights from late May to early July, but is mostly frequently heard in Eastham and occasionally in Provincetown. You can also easily hear the high pitched "peep" of the common and widespread spring peeper. Occasionally, you will also hear the loose banjo string "glunk" call of the green frog. About halfway through the recording, the slow deep grunting call of the American bullfrog can also be heard, but you have to listen carefully.

The second was recorded on April, 28, 2013 in the dunes of Provincetown, at dune slack wetland P31 near Province Lands Road. It has a loud chorus of Fowler's toads (our most common toad species), with an electric buzzing call, and several spring peepers.

Cape Cod

In the mid-19th century, Henry David Thoreau walked the Atlantic coastline of Cape Cod, recording his adventures in his narrative "Cape Cod". To literally follow in Thoreau’s footsteps today would require scuba gear. Cape Cod’s Outer Beach sees an average erosion rate of close to 4 feet per year.
