Big Bird

The Bird is the first boss found in Super Mario Land 2: 6 Golden Coins. He lives in his giant nest at the top of of the Tree Zone and guards one of the six Golden Coins, which is hidden in a huge egg. The bird attacks Mario by swooping at him. In order to defeat him, Mario has to jump on his head three times or hit him with six fireballs. After the bird is defeated, the Golden Coin of the Tree Zone is revealed from the egg. His swooping behavior is somewhat similar to Hoo from Super Princess Peach.

The bird reappears in the comic Mario vs. Wario, where he gets hit by the witch after she launches her fire and gets burnt.
