Abstract

Lesbia ortoni Lawrence, 1869, collected in the Quite Valley, Ecuador, is shown to be a hybrid between Lesbia victoriae and Ramphomicron microrhynchum, sympatric inhabitants of Andean forest edge and shrublands from Colombia to Peru. The hybrid exhibits a blended mosaic of plumage characters of the parental species. Although the parental species differ significantly in size, the external measurements of the hybrid approximate those predicted by least squares regression.
