Belonging to the parrot family, cockatoos have a natural ability to mimic other species, including humans. Additionally, the birds quickly discover how their own species communicates and are able to distinguish whether other birds are part of their family or not. This way, they can prevent territorial issues and identify potential mates.
Moreover, if other birds are not present, a parrot can start to copy whatever noises and voices it is subjected to. That is why those kept as pets are renowned for imitating human speech. Parrots are the most famous species for doing this, though beluga whales and elephants also use mimicry on occasion.
In the case of this particular cockatoo, a YouTube video captured the hilarious moment between the bird and three cats. The clip shows the white parrot sharing a bed with the moggies. Then the inquisitive squawker does the strangest thing in a bid to communicate with them.
