Herpetofauna - One Life's List

Ramsey Canyon Leopard Frog
Rana subaquavocalis

Huachuca Mts., Arizona. August 4, 2000.


What constitutes a Life List sighting? This was a tough one, since our only way to see a Ramsey Canyon Leopard Frog was to use binoculars.  What could we see?  Only the eyes and the top of the head, sticking out of the vegetation in this little man-made pond.

This rarest of North American frogs was only discovered a few years ago, when its small population had further diminished to just a handful, perhaps a hundred.  They are only found here and in another nearby canyon, and most of the frogs left are in the manmade pond pictured here.  Efforts are being made to increase their numbers and establish other populations of the frog.

What makes them unique is the male frogs call while underwater, a trait unknown among other North American frogs.

They teeter on the brink of extinction. Here are some links for more information:
