Along with breathtaking beauty, when personality is factored in to describing a small hookbill, rosellas are loaded with spirit.   Although seldom handleable, they take great interest in everyone and everything around them.  They are very responsive and communicative with mellow voices lacking the shrillness associated with other parrots of similar size.  Our Golden Mantled Rosella especially loves to whistle tunes to popular songs and he does it complete with feeling and motions.
