My Peterson Field Guides for Western NA and for Mexican Birds says that the
Willow Flycatcher is found from Alaska to Canada to sw and e.-cen US. and
winters from Mexico to Argentina.
Is the "southwestern" willow flycatcher a seperate species or just the ones
that live in that area?
Is the issue here one of loss of wetland and therefore loss of food supply
or is it nesting habitat?
