Bat
From Memory Alpha, the free Star Trek reference
A bat was a winged mammal native to Earth.
Early models of da Vinci's flying machines were based on bats or sparrows. Kathryn Janeway suggested to base them on hawks instead. (VOY: "Scorpion")
When Spock tried to match the sound of the whale probe to the sound of an Earth animal aboard the Klingon Bird-of-Prey HMS Bounty, a long-legged myotis (Myotis volans) was one of the animals shown. (Star Trek IV: The Voyage Home)
