Pollination is the transfer of pollen from the anther to the stigma. Many animals act as pollinators, including insects like bees, birds, and bats. Bees are well-known pollinators due to their frequent visits to flowers for nectar and pollen. Birds, particularly those with long beaks like sunbirds, can transfer pollen while feeding on nectar. Bats, especially fruit bats and some nectar-feeding bats, are also important nocturnal pollinators for certain plant species, visiting flowers to feed on nectar and pollen.
