speaking of possessive. Rio was in to the Pam spray can but has now taken on medicine bottles. I think they are his girl friends and the boy has a haremI have definitely seen the wiggle neck in Kiwi, although quite rarely perhaps because she’s a female. I have heard of parrotlets doing the wiggle neck to toys and other inanimate objects as kind of a possessive thing too. I agree with the others - ignore it even if it is super cute and funny. I have never seen this dance though! That’s fascinating!
