They are primarily found in New Zealand in the forest.
There are about nine distinct species of them.
They are omnivores and are opportunistic hunters, eating whatever they happen to find in their territory.
Their wings are very flexible enabling them to hunt on the forest floor as well as hunting insects via flight, or landing on plants to eat from them.
They have large pointed ears, and a free tail. They are an important pollinator.
Rats and loss of habitat are major threats.
"Short-tailed bats are the only species of small bat which carry out lek mating (where males assemble in a special area and compete for the attention of females). During late summer, male short-tailed bats gather at strategic trees near communal roosts and attempt to attract females with prolonged singing bouts"
