Have you ever wondered what defines a species vs. a subspecies? Come find out with hummingbird researcher, Dr. Caroline Judy. She will present on her work studying an unusual case of island speciation seen in Jamaican streamertail hummingbirds (Trochilus spp). Streamertail hummingbirds are closely-related hummingbirds that are distinguished on the basis of bill color, which is bright red in the Red-billed Streamertail and jet black in the Black-billed Streamertail. Historically, they have been treated as subspecies by the North American Classification and Nomenclature Committee. However, Dr. Judy found evidence for reproductive isolation that informed the committee’s recent decision to elevate streamertail hummingbirds to full species status. She also will discuss many aspects of streamertail biology that are common to all hummingbirds and ask the ultimate question – why are hummingbirds as a genus so rich in species? Register now.
