The foul-mouthed birds were split up after they launched a number of different expletives at visitors and staff just days after being donated to Lincolnshire Wildlife Park in eastern England.
"It just went ballistic, they were all swearing," the venue's chief executive Steve Nichols told CNN Travel on Tuesday. "We were a little concerned about the children."
"I get called a fat t**t every time I walk past," Nichols complained.
The African grey parrots -- named Eric, Jade, Elsie, Tyson and Billy -- were given to the park from five different owners within the same week, and shared a quarantining facility together before being placed on display.
But staff immediately noticed that the birds shared a propensity to fly off the handle.
