Rana aurora — Northern Red-legged Frog
The California Red-legged Frog (Rana draytonii) was recently split off from this species.
Although its California cousins are rare and growing rarer, this species seems to be thriving, at least in the various streams, ponds, and lakes that I visited on our summer trip. These three photos show three progressively larger individuals that I saw in different places on the same day. The first one pictured here was probably a tadpole not too long ago; it was about an inch long, living in a large pond. The second one was about 2 1/2 inches long, and was living in a stream. The third and fourth photos show the same nice big fat frog, about 4 inches long. It was leaping about on the forest floor in the general vicinity of a stream.
Here's another fairly young frog, living in some really disgusting muck at the edges of the aptly-named Mud Lake.
