All natalids roost deep in caves where it is hot and humid and the climate changes little. Individuals hang in widely
spaced colonies of up to 300. Northern populations of N. stramineus may migrate in winter. In between foraging bouts, natalids may roost under overhanging rock ledges outside caves.
Funnel-eared bats (Natalus stramineus) have long slender wings. (Photo by Heather A. York. Reproduced by permission.)
