I wish Flamingos were more like Pandas. The male panda Gu-Gu at the Beijing (Peking) zoo has attacked (and sent to the Hospital) men in three incidents that have broken into its enclosure. Given that the Panda has never attacked its keepers, the zoo has no interest in replacing the Panda (and sending this one to a breeding facility).
