I am in Georgetown this week for the Texas Master Naturalist state conference so no Park blog post, but I did see an amazing Tricolored bat at Longhorn Cavern. It is called a Tricolored bat because each hair goes from black at the base to yellow in the middle to brown at the tip. Tricolored bats are much much smaller than the Mexican free-tailed bats we have in our Park. These guys are as small as 4 grams. The free-tails are over 12.
