Natalus stramineus

Mexican Greater Funnel-eared Bat

Order: Chiroptera
Family: Natalidae

 

Conservation Status: Least Concern.


These tiny bats have such sensitive echolocation systems that they usually avoid mist nets. Mist nets are made of very fine threads and are important to scientists studying bats. Bats that blunder into the nets get entangled, but are almost always not hurt and can be gently freed, studied, perhaps tagged, and then released.

Mexican Greater Funnel-eared Bats flutter through the understory of the forest, pursuing small, flying insects. Groups of up to 300 often share large caves. They roost well apart from each other, deep in the cave, and fly out about half an hour after sunset to forage. Females usually bear a single young, born late in dry season, and are known to join other females and their offspring in maternity colonies.
