Bats and Agaves: An Interconnected Relationship of Birth, Life, and Death

Pregnant migratory bats need the sweet nectar from agaves to make their annual journey north from central Mexico to the U.S. Southwest to give birth to a single pup. Agaves depend on migratory bats to pick up pollen as they feed to ultimately propagate new plants.  Learn more about this interconnected relationship and what’s being done to save bats and agaves.
