Plate 148 – Pine Swamp Warbler

While exploring the Great Pine Swamp (see Plate 88) in the summer of 1829, John James Audubon collected a specimen of the Pine Swamp Warbler. Audubon then doubted the existence the Pine Swamp Warbler: “the young of the Black-throated Blue warbler (Plate 155), the female of which resembles them so much that I looked upon it as of a species distinct from the male.” For the later octavo edition of Birds of America, Audubon re-identified the male Pine Swamp Warbler as a female Black-throated Blue warbler and declared that the Pine Swamp Warbler “must be erased from our Fauna.”
