Bo the Mexican free-tailed bat is one of 100 million bats that live in Texas, and in this colorful picture book, he takes children on an exciting trip across the Lone Star State and educates readers with dozens of "bat facts." There are thirty-two different species of bats living in Texas and more than one million living under the Congress Avenue Bridge in Austin. Bo and his friends can be found all over, but most people will never see them up close. They love to hide, and caves are great places for that. In fact, the largest bat colony on earth can be found in Bracken Cave, near San Antonio. There are almost as many bats in that one cave as there are people in the entire state One in every four mammals is a bat, and bats help control mosquito populations. Bo explains echolocation and how it's used to help bats hunt and fly, and he explores the great state of Texas from a unique bat's eye view.
