Abstract

The unique hummingbird specimen collected by J. W. Sefton, Jr., in 1932 in the Rincon Mountains, southeastern Arizona, is confirmed to be a hybrid, Calypte costae × Selasphorus platycercus. The hybrid exhibits a blended mosaic of plumage characters of the parental species. Other parental hypotheses were ruled out on the basis of plumage color and on measurements of the outermost rectrix (R5).
