Mexican Long-Nosed Bats Now Being Spotted In Southeastern Arizona

Researchers say they now can tell the endangered species apart from other bats by analyzing saliva left behind when sipping nectar.
FLAGSTAFF, Ariz. (AP) — Scientists have long suspected that Mexican long-nosed bats migrate through southeastern Arizona, but without capturing and measuring the night-flying creatures, proof has been elusive.
Researchers say they now have a way to tell the endangered species apart from other bats by analyzing saliva the nocturnal mammals leave behind when sipping nectar from plants and residential hummingbird feeders.
Bat Conservation International, a nonprofit group working to end the extinction of bat species worldwide, teamed up with residents from southeastern Arizona, southwestern New Mexico and west Texas for the saliva swabbing campaign.
The samples of saliva left along potential migration routes were sent to a lab at Northern Arizona University in Flagstaff, where researchers looked for environmental DNA — or eDNA — to confirm that the bats cycle through Arizona and consider the region their part-time home.
The Mexican long-nosed bat has been listed as endangered under the Endangered Species Act since 1988, and is the only one in Arizona with that federal protection. It is an important species for pollinating cactus, agave and other desert plants.
