ID pending...found on middlebury college field trip. No dorsal ridges and no scent
Small frog, approx 2 inches long. Very common along this boardwalk, but very hard to see for photographic capture.
Habitat was a beaver pond in an boggy woodland, fringed with sphagnum, tamarac, and fir.
Individual observed while calling. A female mink frog was also captured in the vicinity.
3 calling mink frogs were noted at the pond.
The presence of 16 calling male mink frogs was noted during call surveys. Activity was focused in pockets along the southern edge of the marsh.
Two calling mink frogs were heard while conducting point-count call surveys. Night surveys also recorded two calling males.
I observed Mink Frogs (Rana sepentrionalis) making breeding calls on South Branch Pond in Baxter State Park in the North Woods of Maine.
The sounds I recorded that evening can be found here:
The photo was taken at the same pond two years previous on July 10, 2009.
The mink frog (Lithobates septentrionalis) is a small species of frog native to the United States and Canada. They are so named for their scent, which reportedly smells like a mink. The scent is more akin to that of rotting onions to those unfamiliar with mink. It is also sometimes referred to as the north frog.
