Podiceps auritus

Podiceps auritius

The Podiceps auritius was a creature native to Earth.

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 Podiceps auritus was one of the animals shown. (Star Trek IV: The Voyage Home)

Podiceps auritus is actually the scientific name for a horned grebe, although an image of a whale was shown instead on the Bird-of-Prey's display.
