Mexican Long-nosed Bat (Leptonycteris nivalis) lives in canyons across Southwestern North America. It feeds on nectar & pollen. Its conservation status is Endangered.
Fascinating facts about the Mexican Long-nosed Bat
- The greater long-nosed bat's tail is unusually short, containing only three vertebrae, which limits its length compared with many other bats. Its interfemoral membrane is covered with a moderate amount of fur, giving it a slightly plush appearance. The forearms measure between 54 and 59 mm, providing the wing surface needed for agile flight in desert scrub. Ears about 15 mm long complete its compact head morphology.
- Mating for this species occurs in November and December inside the single known cave, Cueva del Diablo, where the bats gather each year. The timing is synchronized with the peak flowering of local plants, ensuring the greatest availability of nectar and pollen for the courting individuals. Researchers believe the bats practice a polygynandrous system, with both sexes mating multiple times with different partners.
- After decades of decline, the species showed a notable rebound in the United States, with the Arizona population expanding to one hundred times its 1984 size by the year 2000. The species was listed as endangered by the U.S. Fish and Wildlife Service in 1988.
- Beyond caves and mines, these bats also roost in unoccupied buildings, hollow trees and even sewers, showing a willingness to use a variety of structures. Their range includes southern Texas, Arizona and New Mexico during the summer months of June to August, while they occupy central Mexico for the rest of the year.
- Its dentition is reduced, lacking the third molar entirely and leaving only two weakly cusped molars, a condition typical of nectar-feeding bats. The loss of teeth and dental ridges accurately reflects a diet that does not require biting or chewing, as the bat mainly consumes pollen and nectar. Complementing this, the species possesses an elongated muzzle and a long tongue tipped with filiform papillae that can probe deep into flowers.
