Birdy is a large skeleton bird with red eye sockets. It makes crow sounds.
Birdy sits stationary on a perch until Ninja approaches within range. When Ninja approaches, Birdy will take flight. Birdy will fly and attempt to ram through Ninja, continue flying a little onward past Ninja due to acceleration, then slow down and fly at Ninja again. Birdy can also pass through walls in order to reach Ninja.
- Birdy is referred to as "crow" in the sound files.
- In the beta version of the game, Birdies used to have the same sound effect as Bats. Video.
