I'm really rusty on the frogs out there. Our early spring ones are the
Spring Peepers in the trees and bushes and Upland Chorus Frogs at the
water, along with the American Toad and Southern Leopard Frog. At least
where I live, other parts of Georgia have others. The only chorus frog
in your area is the Pacific Treefrog, the one you are hearing up in the
bushes and so on. If you are hearing another frog, it's probably a
Ranid. Rana aurora, the Northern Red Legged Frog occurs in your area.
Your other choices are the Western Toad, Bufo boreas, and the Tailed
Frog, Ascaphus truei. I know the call of the Pacific Treefrog, don't
know the others right off.

I spent many years studying biologic subjects at Oregon State
University, so am familiar with the climate. Did a good part of my
younger years in the NW as well. At 38F, the Spring Peepers are happy
here too. And wind is a factor for them since they call from up in the
branches. Even frogs that call from the water slow down when it's windy.
Around here most of the real windy periods in the winter are cold air
coming down from the north. Not much between us and the north pole. Cold
here is around 0-5F, though that's not all that common. We can be
anywhere from that to the 70's in January, depending on where it comes
from. Today is in the 60's, first warm day in a week or two.

Right now I'm in the process of redoing the utilities in mine, replacing
heater, controller and blower. So it's out of action at the moment. But
you certainly get to notice what's going on.
