"The sexual dimorphism and evolution of this species is closely tied to the two heliconias native to the Lesser Antilles: Heliconia bihai and Heliconia caribaea. Male Purple-throated Caribs exclude females from Heliconia caribaea through territoriality, but are prevented from feeding at all but the shortest-flowered Heliconia bihai plants due to their shorter bills. This renders males inferior in exploitative competition with the longer-billed females, leading to sexual partitioning of these two plant species driven by intraspecific competition. The two heliconias do not occur in equal abundance on many islands within the Lesser Antilles, and whichever heliconia is more common develops a second color morph with flowers and energy rewards corresponding to the sex of its primary pollinator."
