Noun
An animal which eats the sugar-rich nectar produced by flowering plants. Most nectarivores are insects or birds, but there are also nectarivorous mammals, notably several species of bats in the Southwestern United States and Mexico, as well as the Australian Honey Possum (T. rostratus), and Geckos (genus Phesulma) in Mauritius. The term is less exclusive than other -vores; many animals that are considered nectarivorous may also be insectivorous. Many species are nectar robbers, performing no pollination services to a plant while still consuming nectar. (wikipedia.org)
Word origin: From from Latin nectar, from Greek nektar, name of the drink of the gods, which is said to be a compound of nek– “death” + from Latin vorare, “to devour.”
