Boreal Chorus Frog is one of the few species around here - very common -
although I haven't ever heard one make a two-part 'ribbit' call. There are
Pacific Tree frogs a few hundred km southwest of my location, and the
pattern is certainly similar to your mystery frog, but there is something
about the tone of the call that makes me think yours is an abberant boreal
chorus frog....unless there are any other potential candidates? Any other
tree frog types that are closer in range?
I have found Pacific Tree Frogs in habitat similar to what Boreal Chorus
Frogs use in this area (shallow grassy ponds)
