The hoary bat is a stunning bat with dark gray and brown fur, covered in white, frost-like tips. Hoary bats are one of the largest in America, with females being larger than males. This species is more likely to avoid roosting in human made structures, preferring wooded areas where it can hang alone, high up in the trees and along forest borders. When foraging for a meal, the hoary bat prefers to dine primarily on moths. Wind turbines have posed a significant threat to this species, with hoary bats suffering mortality due to impact with turbine blades.
