The Bumblebee Hummingbirds (Atthis heloisa) of Ramsey Canyon Revisited
Christopher W. Swarth
ABSTRACT: The provenance of the two specimens constituting the only evidence of the occurrence of the Bumblebee Hummingbird in the United States has been questioned. But their origin in or near Ramsey Canyon, Arizona, in 1896 is confirmed from the journal of Harry S. Swarth, one of the four collectors who mounted an expedition to the Huachuca Mountains that year. In his journal, Swarth mentioned them as unidentified hummingbirds, one collected in Miller Canyon on 29 June 1896, the other in Brown’s Canyon, a side canyon of Ramsey Canyon, the following day.
