Description

The Mexican funnel-eared bat gets its name from its very distinctive funnel-shaped ears. The face has a triangular shape, pale skin, and forward-tilting ears. Both sexes of this species are similar in size, unlike other species. They have brown fur, which becomes darker as it reaches the tip.^[3] They tend to live in deep and very humid caves and have groups from 100 up to 10,000 bats.^[4] Another prime difference in this bat species compared to other, is that the Natalus stramineus has the longest genstation period reported for bats (some seven months). The Mexican funnel-eared bat also has migrant characteristics since it must live in a highly humid environment. If the habitat is not as humid as their liking, their population in that habitat will drop due to many of the bats looking for a more suitable place to call home nearby.^[5] This species displays slower flight speeds than others; as insectivores, the Natalus stramineus needs greater mobility to catch insects in densely vegetated areas.^[6]
