Budgie
 

A man buys a budgie and when he gets it home it just keeps repeating "I'm a Geordie budgie! I'm tough as nails!” After a week the man gets so fed up he buys a kestrel and puts it in the cage. "Let’s see how tough you are now" he says.
Next morning he comes downstairs and the kestrel is dead. Budgie says "I'm a Geordie budgie! I'm tough as nails!” So the man buys a buzzard and puts it in the cage.
Next morning the man comes downstairs and the buzzard is dead. Budgie says "I'm a Geordie budgie! I'm tough as nails!” So the man buys a golden eagle and puts it in the cage.
Next morning the man comes downstairs, the eagle is dead and the budgie has no feathers left. Budgie says "I had to take me jacket off for that fucker!"

that is one bad bird...
