Red-legged Frog

The Red-legged Frog, a threatened native species in Oregon,^[1] is a common name for a particular kind of frog of the west coast of North America. The Red-legged Frog requires stream side, woodland environments for survival. The Red-legged Frog is further subdivided into two categories:

California Red-legged Frog, Rana draytonii
Northern Red-legged Frog, Rana aurora

These two have long been thought mere subspecies of Rana aurora, R. a. draytonii and R. a. aurora, respectively, with "Red-legged Frog" accordingly applying to that species as a whole. Analysis of mtDNA cytochrome b sequence data points to their being two distinct species however.^[2]
