The green - or brown - frog with a big voice as photographed by Nan Brichetto

Nan Brichetto came across this little green frog on the gravel banks of the Gualala River. It's a Chorus Frog or Sierran Tree Frog. It used to be called  a Pacific Tree Frog but its name was changed recently.

These frogs have a big call which sounds like "ribbit, ribbit." They are able to change their color to match their surroundings. Below is a Tree Frog changing from green to rusty red. This was photographed by Clay Yale.

It must be nice to be able to camouflage oneself! Thanks to Nan and Clay for allowing me to share their photos with you here.
