Alex the Parrot learned how to use syntax and grammar, as well as invented his own portmanteaus of existing words to describe complex and mixed ideas.

He also learned the concept of zero (he was like 30 years old, but still) and is the only non-human animal to ask an existential question: "What color am I?"

There is the parrot called Apollo on Youtube that will probably get pretty close to that if not accomplish it. They are like only three years in and the parrot is pretty damn good at categorizing things, even things he hasn't seen before, into categories based on its color, texture, etc. but like everything held above your head is a 'hat' so like true comprehension isn't there.

Edit: you already referenced him lol
