Sorry to be a pest!
I recorded this yesterday at a slough about 5 miles south of
Saskatoon, SK. Sorry about the quality - I've edited out as much wind
noise as I could.

According to what I've been able to find on the web, the 3 frogs found
in Saskatchewan are Boreal Chorus, Wood and Northern Leopard. I'm
familiar with the calls of the first two and have listened to
recordings of the Northern Leopard. The first frog that starts calling
in the centre of the recording's stereo field makes a sound commonly
transliterated as "ribbit" and doesn't sound like any of the three. It
is then joined on the right side by a loud Boreal Chorus (BC) frog.
I've never heard the BC make a "ribbit" sound.
The only recording of a Canadian frog that I can find that sounds a
bit like it is a Pacific Tree Frog which would be way outside its
normal range, apart from which I don't think it inhabits sloughs anyway.
Is this a Boreal Chorus frog being awkward or a different species
altogether?
Thanks
Pete
