Can Fawkes apperate on school grounds?

I was just reading OOP for the fifth time and it all of a sudden hit 
me... Several times in the 5 books we are reminded that no one can 
either apparate or disapparate on/in school grounds. (Not only from 
Hermione several times but from other students and teachers as well) 
In OOP, Fawkes disappears to go and do jobs for Dumbledore, and then 
when Fudge tries to take Dumbledore out of the school, (after 
Dumbledore takes responsibility for the D.A. club) the book tells us 
the Dumbledore took ahold of Fawkes' tail and they were 
gone/disappeared. Do the rules not apply to animals? Because, what 
Fawkes did sure sounds alot like Disapparating to me. At least now, 
we have solved how Dumbledore gets around to places so quickly. 
Please let me know your theories. Thanks,
