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.

These little frogs, usually colored green, show up in the strangest places. Susan Gonzalez photographed one on a wire structure over her pond. The wire protects her fish from Great Blue Herons and other critters after an easy meal. The Tree Frog looks a little precarious up on the wire.

Thanks to Susan for sharing her photo with us. To see a Tree Frog with an attitude, here's the link: http://www.mendonomasightings.com/2012/02/25/pacific-tree-frog-with-an-attitude-as-photographed-by-cathleen-crosby/

This past week Cathleen Crosby and her granddaughter, Tali, came across a small Pacific Tree Frog on The Sea Ranch. The way it's looking at Cathleen's camera makes me think this frog has an attitude! This would be a fun photo to have a caption contest.

This is the only frog who's call is "ribbitt, ribbitt." It is usually green but can change color to help camouflage itself. These frogs are found on the West Coast all the way up to British Columbia. To see another photo Cathleen took of a Pacific Tree Frog on a spa, here's the link: http://www.mendonomasightings.com/2011/10/21/a-tiny-frog-with-a-big-voice-meet-the-pacific-tree-frog/

Cathleen Crosby recently photographed a Pacific Tree Frog, Pseudacris regilla, sitting on her spa. This frog can change colors to match their environment but they can't change to match a blue spa. Usually they are green but I've seen them turn brown and rusty-red. They eat insects, occasionally almost as big as they are. They have the ability to expand their body, something that would be helpful for humans at Thanksgiving!

This small frog is found on the west coast of the United States. Males are slightly smaller than the females and they have a black patch on their throats. This patch is actually their vocal sac. I can attest to the loudness of a male calling for a mate. Here Peter Baye photographed one in "full throat." Fun fact - this is the only frog who's call is "ribbitt."
