Cockatoo Coalition to protect this bird

Theme park bosses have been forced to start offering visitors weird-looking umbrella hats -- to stop birds from pooing on them.
Zoo keepers at Chessington World of Adventure say they noticed many visitors to their walk-through aviary were ending up with poop on their head.
And while it's meant to be considered lucky, few guests agreed and many were even being put off visiting by the prospect of being pelted by parrot poo.
