#plate 88

[thebirdsofamerica]

Plate 88 of The Birds of America by John Audubon, the Autumnal Warbler, now thought to be immature Bay-breasted Warblers. Their showing up at a certain time of year parallels the Winter Hawk plumage mistake Audubon made. (This isn't a criticism of Audubon. He certainly didn't have the tools or knowledge base of today's ornithologists.)
