| | Birding in Cincinnati - The Cincinnati Warb;er |
 | | In his description of the Cincinnati Warbler, Langdon wrote that Dr. Elliott Coues, who examined the specimen on Langdon’s behalf, believed "its relations are mainly with Helminthophaga pinus [Blue-Winged Warbler], although in the concealed fl of vertex and auriculars it slightly resembles certain plumages of Oporornis formosa," or Kentucky Warbler. |
 | | If it were encountered today, the Cincinnati Warbler’s fl auricular patch, which looks like it has been cut right off the head of a Kentucky Warbler, and the mix-and-match Kentucky and Blue-winged Warbler characteristics clearly would mark this bird as some kind of a hybrid, not a new species. |
 | | Kentucky Warbler was all but ruled out, in large part because in 1948, there were only three records of that warbler in Michigan, while Mourning Warbler was known to breed just north of the location where the Michigan warbler was collected. |
