Fighters? Males defend unusually large territories.
Lovers? Their territories include a Heliconia species whose nectar only female E. jugularis can reach with their long, curved beaks. Males gain an advantage in mating by allowing females to feed on the flowers.
Farmers? It’s the first time researchers have documented male birds guarding a food only females eat. Study authors W. John Kress of Smithsonian’s National Museum of Natural History and Ethan Temeles of Amherst College call it “nectar farming.”
