I guess the uppermost one is higher in the pecking order, Martin! We have some here in New Zealand, seemingly imported and then released into the wild. Up until now, I have thought that the ones we see have been Rosellas, however, looking at the evidence, it seems that they are probably Lorikeets. Love the pic!
Yes, Jim that is the pecking order! Thanks for your comment
