Nectarivory

Nectarivory is a feeding strategy based primarily on consuming floral nectar. It occurs in diverse animal groups and often involves adaptations for locating and extracting nectar.

Floral nectar: A sugar-rich liquid produced by plants, usually in specialized glands called nectaries. It is the primary food resource that defines nectarivory.
Hummingbird: A small New World bird, many species of which feed heavily on nectar. Hummingbirds are among the best-known specialized vertebrate nectarivores.
Pollination: The transfer of pollen from an anther to a receptive stigma, enabling plant fertilization. Nectarivores can transfer pollen while visiting flowers for food.
Frugivory: A feeding strategy based primarily on consuming fruit. Frugivores eat mature fruit rather than floral nectar as their main food.
Animal diet: The foods an animal consumes and the pattern of its food intake. Nectarivory is a dietary strategy defined by a dominant food source.
Nectarivore: An animal whose diet consists primarily of floral nectar. Nectarivores vary widely in the structures they use to obtain nectar.
Honeyeater: A family of Australasian passerine birds that commonly feed on nectar. Honeyeaters illustrate nectarivory among perching birds.
Pollinator syndrome: A set of floral traits associated with pollination by particular animal groups. Nectarivore traits help explain why flowers differ in shape, color, scent, and nectar placement.
Granivory: A feeding strategy based primarily on consuming seeds or grains. Granivores rely on energy stored in seeds instead of nectar.
Ecological niche: The conditions and resources that shape a species’ survival and ecological role. Nectarivory occupies a niche defined by floral resources and feeding opportunities.
