Bird in solitary confinement after abusing zoo visitors Initially the birds, imported to the Chinese zoo from Vietnam, were a success, winning visitors over with their "lovely appearances and clever tongues." Maybe some tourist taught the bird this bad language. To avoid contaminating its cage mates, the animal, which was not named, has reportedly been placed in solitary confinement where it is undergoing "special training." Keen to rehabilitate the foul-mouthed bird, zookeepers have been playing it tapes containing "polite words." Future offenders will be deprived of food, the newspaper added. Meanwhile visitors have been asked to refrain from teaching cuss words to the birds. "Human behaviour will affect the animals," Mr Li said. A sign has also been erected at the zoo. "'Please do not use foul language to get a rise out of the Myna," it says.
