🖤 Bracken Cave appreciation post 🖤 Located just 20 miles outside of San Antonio, TX, Bracken Cave is home to the largest bat colony in the world — home to over 20 million Mexican free-tailed bats. Bracken Cave is a maternity roost, meaning expectant female bats return to roost in Bracken in the spring, after overwintering in South and Central America, to birth their singular bat pup. Witnessing the emergence in person is an unforgettable sight. #battok #bats
