Neuroscientists from the Alberta University have identified parrot as the most intelligent bird and the African gray parrot is regarded as one of the most intelligent bird species on the planet.

Recently, a British zoo has moved out five African gray parrots from the display as they keep using cuss words in the visitors’ presence.

According to the details, the Lincolnshire Wildlife Park said they removed five African gray parrots from the visitors’ view after the “nonstop cursing ruffled some feathers”.

Steve Nichols, park CEO told an International news outlet,

“Some visitors found it funny but with kids visiting at weekends, we decided to move them. 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.”

“They were all (cursing) and blinding at each other, which was funny, but when they went outside they were quite offensive to some of the visitors,” Nichols added.

“It caused some concern as people didn’t realize it was the parrots at first, as it can sound like it is a person’s voice, but then they loved it.”
