Here is one bird you don't want to mess with.

As an owner of a Goffin Cockatoo and former owner of a Moluccan Cockatoo, you should know that is is never a good idea to put a large bird into a round birdcage.

A bird cage for a large tropical bird needs to be very large and this cockatoo knows it very well.

WARNING: INTENSE LANGUAGE

 

Here is the backstory, according to MrtechnicalDifficult, The cage being destroyed is the Cockatoo's cage. The Man in the video takes in rescue birds.

He had received a full grown parrot in this tiny cage (which is borderline abuse) so he destroyed it with another bird (who has quite a mouth) named pebbles, and trying to advocate that birds hate living in tiny ass cages like that one.

The bird is okay, just needs a little adjustment in his language skills.
