Mexican Greater Funnel-eared Bat (Natalus mexicanus) lives in tropical dry forest across North America. It feeds on insects and spiders. Its conservation status is Least Concern.
Fascinating facts about the Mexican Greater Funnel-eared Bat
- The Mexican greater funnel-eared bat is exceptionally tiny, weighing just three to five grams. Its forearms measure thirty-six to thirty-nine millimetres; its back is pale orange-brown or yellow, its belly uniformly yellow, and its broad, cream-coloured ears have dark margins, with very long limbs and narrow, pale brown flight membranes.
- Female Mexican greater funnel-eared bats become pregnant only once each year, a condition known as monoestrous. Observations show pregnant individuals from January through July, and the slow fetal development suggests a gestation period of eight to ten months. Each successful pregnancy yields a single pup, reflecting the species' low reproductive output. This timing aligns with the bat's annual cycle in its tropical range.
- During daylight hours the Mexican greater funnel-eared bat gathers in caves, forming colonies that can contain up to three hundred individuals. This roosting behaviour is consistent across its range, reinforcing its colonial nature.
- The Mexican greater funnel-eared bat never occurs above 2,400 m, and most records come from sites near 300 m elevation. It is most common in dry and semi-deciduous forests, although individuals have also been found in conifer forests. Its distribution spans Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua and Panama, linking its habitat preference to low-land forest environments across Central America.
- In 2012 the Mexican bat Natalus lanatus was merged with Natalus mexicanus, leaving a single recognised funnel-eared bat species in Mexico. This taxonomic change follows earlier revisions: in 1959 the bat was demoted to a subspecies of Natalus stramineus, and in 2006 it was restored to full species status. The result is that N. mexicanus now stands as the sole representative of its genus within the country.
