[2] 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.

[3] They tend to live in deep and very humid caves and have groups from 100 up to 10,000 bats.

The Mexican funnel-eared bat also has migrant characteristics since it must live in a highly humid environment.

[5] This species displays slower flight speeds than others; as insectivores, the Natalus stramineus needs greater mobility to catch insects in densely vegetated areas.
