This sounds like an exhibit they could have probably charged visitors extra to see.
At the British zoo Lincolnshire Wildlife Centre, keeping some of the bird residents’ vocabulary limited to G-rated language has proven challenging — and park employees had to go as far as separating five African grey parrots to squash the swearing.
. . .
Nichols told BBC News that the foul-mouthed birds would “swear to trigger a reaction or a response,” so when park visitors burst into laughter or other birds reacted at their interjections, they’d hurl more bad words.
“With the five, one would swear and another would laugh and that would carry on,” he said. “… Some visitors found it funny but with kids visiting at weekends, we decided to move them.”
Added Nichols: “I’m hoping they learn different words within colonies — but if they teach the others bad language and I end up with 250 swearing birds, I don’t know what we’ll do.”
