What species of frog is this?

[Gnag the nameless]

Alright, so today, my friend was out in his backyard taking a look for newts, as they usually come out at this time of the year. He found one newt, and oddly enough, a frog! This is the second time he's found a frog in his yard, and not only does he rarely see them, but most strange is that almost all frogs are hibernating in my area. It wasn't moving much, neither responding. However, it's become more active since, and my friend has set up a crude 10 Gallon tank setup for it. He's immediately contacted me, as he has lots of experience with newts but not frogs. He's also sent me some pictures, and I'm heading to his house tomorrow. Before then, though, we'd like to know what species it is as soon as possible. I'm thinking it's either a Red Legged frog (Rana aurora) or a Pacific Chorus frog.

My friend is assuming it's a red legged frog (Rana aurora) but I'm doubting it due to it's coloration. Anyone know for sure?



You can see the Red legs here, but it's coloration resembles more of a Pacific Chorus frog.
