Warbler Guy, which wood-warblers are endemic nesters to the continental U.S.? More specific, which wood-warblers ONLY nest in the USA, and NOT in Canada and Mexico, etc.?

Posted on by

For your first question, Giselle, the answer:

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 state. Golden-cheeked is restricted to nesting ONLY in Texas, but migrates south during the non-breeding season.


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 and Alaska) among places where it breeds in the northern U.S. and farther north.
