Tennessee Warbler could have been the Canada Warbler...

Except for the fact that there is already a Canada Warbler, I think the Tennessee Warbler could be named the Canada Warbler, as its entire breeding range is found almost exclusively within Canada, from British Columbia across to Newfoundland, minus a wee smidge of territory in south-west Alaska.

It is only found in the lower U.S.A. during its fall migration en-route to the Caribbean.

It's not especially noteworthy colour-wise and its nest is on the ground (not easy to see).

Please comment if you wish.
