Hi All
As far as I know there are two Canadian collections. One is Bird Sounds of
Canada by Monty Brigham. This is a 6 CD set, keyed to Godfrey's Birds of
Canada. I am not sure when this set was originally produced, but I found
this set was not readily available. It was distributed by Holborne
Distributing Co, Ltd; PO Box 309, Mount Albert, Ontario, L0G 1M0.

The Canadian resource are the recordings of John Neville. These are fairly
recent and available widely. John has produced Bird Songs of the Okanagan,
Bird Songs of the Creston Valley, Birds of the Kootenays, and Songs and
Sounds of the Canadian Rockies.

Hope this helps
