Open Hours: At dusk in mid-summer
The Congress Bridge over Colorado River houses approximately one and a half million bats in mid-summer. In the spring, the pregnant female makes her way north to roosting sites in the Southwestern United States. They each give birth to a baby and at five weeks of age the pups can fly. Hundreds of people line the bridge at dusk to catch a rare glimpse of the bats as they leave the bridge for their nightly feeding. It may take up to 45 minutes for all the bats to exit. They will consume between 10,000 and 30,000 pounds of insects each night.
