Zoo had to separate African Grey Parrots

[Catherine]

Lincolnshire Wildlife Park introduced 5 African Grey Parrots to the same enclosure. They got along, but the staff soon noticed they were working together to make fun of zoo visitors. The birds would swear at them and laugh at them. They got pretty bad and finally the birds had to be separated.

It does not surprise me. African Grey Parrots are very intelligent. The 5 birds were having fun.
Maybe if people had laughed back at the birds and made fun of them, their reaction might have been different.
Too bad, because I think the birds were having fun.
