Cockatoo identification, for me, is like trying to understand Advanced Geothermal Nuclear Reactions at a Subterranean level ... pretty impossible without an expert "dumbing it down" for me!

*lol* Sorry, I can't help you here ...

Overall body length, color of crest, and the location of coloring on the bird's body can help you identify the subspecies of your friend. There are other characteristics as well.
