What bat eat nectar?

There are three kinds of bats in the world that eat nectar and pollen of plants. Two of the three kinds are found in South and/or Central America. They are called glossophagine bats and lonchophylline bats (Glossophaginae and Lonchophyllinae are the scientific names of the two groups). The third kind of nectar-feeding bats are the macroglossine bats of Africa and Eastern Asia (including Pacific islands).

Glossophagine bats can hyper-extend their tongues an enormous distance out of their mouths. They insert the tongue deep in a flower, and trap nectar in their "paintbrush tips" of their tongues, conveying it back into their mouths for swallowing.

Lonchophylline bats have a deep groove on either side of their tongues. They extend the tongue deep into a flower, and the nectar seems to rise in the groove on each side by capillary action. Glossophagine and Lonchophylline bats have clearly developed specialized structures for nectar-feeding independently of each other.
