Bachman and Audubon spent days together in the field, and long nights talking about plants and animals. In the end, Bachman got scientific credit for discovering two warblers-Bachman's Warbler and Swainson's Warbler, though the latter had actually been first drawn some years earlier by an obscure Georgian artist, John Abbott. Bachman was the first to bring the rare Bachman's Warbler to the attention of science and was the only naturalist to see it alive for half a century. The bird was photographed near Charleston for the last time forty years ago and has not been certainly seen since 1962. The little warbler was never captured alive.
Few skins are in museum collections.
For fifteen years Bachman, Audubon and the Audubon sons worked on Audubon's final opus, Viviparous Quadrupeds , published 1845-1854. The final volumes were finished after the elder Audubon died. Bachman wrote all the text. Here in California we frequently see a third bird named for Rev. Bachman. Audubon gave the Latin name Haematopus bachmanii to this specimen brought back to Philadelphia from the Pacific Coast by Nuttall and Townsend in 1835.
