Plate 55. Double Elephant Folio.
One of Audubon’s five mystery bird “species.” They remain unidentified as such. They are probably hybrids between species. What Audubon called Cuvier’s Wren could be a hybrid between a Ruby-crowned Kinglet and a Golden-crowned Kinglet. If you want to know more, you can read about these five interesting birds, and how Audubon perceived them, in the reference works, or online (search for “Audubon mystery birds”).
