Instead, the short answer: For some wood-warbler species, their routes change from northward to southward migration (or vice-versa), depending on the species.
Consider the Blackpoll Warbler.
An excellent graphic/video shows the change in route of this species in the spring from more Midwestern in flavor to a post-nesting aftertaste whereby migration in the fall is much more easterly, via:

This is so cool, warbler man....Dusky W.
Blackpoll I can tell in spring....but hard to ID on its south migration don't you think?
I saw Blackpoll yesterday birding in IL....Nice views! Thanks for this....
I saw Blackpoll so early this year (by May 9 in IL....). So that's early I suppose? Or not?

Do you ever see females of this sp?
I do, but hard to tell them apart from chickadees, sometimes.....Earl C.
