Info

CHIROPTERA ORDER Chiroptera B ats are especially unique because they are the only group of mammals that have wings and can fly. A few other mammals have “gliding membranes” that allow them to soar through air for a short time, but they cannot truly fly like bats and birds. All Ohio bats are insectivorous and eat flying insects that they can catch on the wing, but some species in other parts of the world may feed on fruit, blood, or other vertebrates. Because bats are nocturnal and it is not easy to see in the dark, they use echolocation to navigate and find food at night. Bats echolocate by making high-pitched sounds which produce sound waves that bounce off objects in the environment. The bats listen to the returning echo to determine details about their surroundings. Bats typically mate in the fall, right before winter hibernation begins. However, ovulation and fertilization of the egg are delayed until the females awake from hibernation the following spring. This is referred to as delayed fertilization.
CHIROPTERA description The fur is uniformly dark brown on the upper parts, with slightly paler, grayish under parts.
