Lesser Long-nosed Bats (Leptonycteris curasoae yerbabuenae) and Parry's Century Plant (Agave parryi) flower stalk. Lesser Long-nosed Bats are specialized for visiting flowers and feeding on nectar and pollen. They have elongated rostrums, long, brush-tipped tongues, reduced tooth number and size, and the ability to subsist on a diet of nectar and pollen. They also consume the fruit of columnar cacti. These bats live in colonies containing thousands of indiduals in "hot" caves and mines. The Lesser long-nosed bat is one of only five bat species that undergoes long distance migrations. These bats spend spring and summer in the SW United States then migrate to central Mexico for the fall and winter. Sonoran Desert, AZ.
