Warbler Guy, which wood-warblers are endemic nesters to the continental U.S.?

Not many, Giselle, as only the Swainson’s, Virginia’s, Kentucky, Hermit, Golden-cheeked, and Yellow-throated Warbler have breeding ranges limited to areas within the lower 48 states.

To clarify, the Blackpoll Warbler does not qualify as an endemic nester to the continental U.S. because it breeds extensively in latitudes north (and into Canada) of the places where it breeds in the northern U.S.
