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.
Seen at FrogWatch Thursday. DLeG says they smell like feet, and boy did this one!
The Mink Frog (Rana 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.
