Warbler Guy, which warbler may disperse &/or migrate by July? Which eastern warbler species is a likely West Coast vagrant?
By contrast, in the spring, during my annual spring jaunt to the Midwest, I'm often sweating by noon while watching the same species in northern deciduous hardwood habitat. There, it’s a common transient through Door County, a northern Wisconsin environ that hosts 16 to 18 nesting warbler species as the farthest southern terminus expression of boreal forest in the lower 48 USA states.
