Well, the cel was of Asuka Jr. from Kaitou Saint 
Tail, so it wasn't worth too much and was easily 
replaceable, but man, can those feathered fiends 
destroy a cel quickly (well, the bird was using 
its beak AND claws in conjunction...)!

(Suddenly glad that I never saw Alfred 
Hitchcock's The Birds movie as a kid or I might 
have been really traumatized.)
