"The sense of smell has been very understudied in birds, particularly songbirds, because they frequently have such impressive plumage and song variation," says Amber Rice, an evolutionary biologist at Lehigh University. "Some other recent work has documented that species of songbird can smell and prefer their species' odors, but this is the first example in currently hybridizing species that we know of."
