ornithophilous การใช้

• As many as 129 species of North American plants have evolved ornithophilous associations.
• Hummingbirds and ornithophilous ( bird-pollinated ) flowers have evolved a mutualistic relationship.
• Hummingbirds are specialized nectarivores and are tied to the ornithophilous flowers upon which they feed.
• The floral characteristics of ornithophilous plants vary greatly among each other compared to closely related insect-pollinated species.
• In tropical dry forests in southern India, ornithophilous flowers were found to bloom mainly in the hot dry season.
• It is generally agreed upon that plants formed coevolutionary relationships with insects first, and ornithophilous species diverged at a later time.
• The white-bellied parrot ( " Pionites leucogaster " ) is a pollinator of the plant, making it ornithophilous.
• The nectar of ornithophilous flowers vary in the sugar composition, with hexoses being high in passerine pollinated species while those that are insect pollinated tend to be sucrose rich.
• The diversity in floral phenotype in ornithophilous species, and the relative consistency observed in bee-pollinated species can be attributed to the direction of the shift in pollinator preference.
