What sub-species of sulphur crested cockatoo is this?

[Nathan1]

Not hugely familiar with all of the sub-species, just wondering if someone else can identify it for me.

Thanks.

Oh and I'd also like to know what makes the sub-species distinguishable other than size...Always like to learn more about birds

I'm not overly familiar with Cockatoos, but if I were to venture a guess, I'd say the bird in the photo is an Eleonora Cockatoo, also known as the Medium Sulphur Crested Cockatoo.

If it has a bald patch behind the crest its a Eleonora { like Wendy said] . Their good size birds [I have one] . But this picture looks more like my LS2 ,which is smaller.

Pretty sure it's a medium sulpher crested
