which seemed to be obvious threat, among the wild birds or directed by the wild birds toward the captive ones. The captive birds may fly about excitedly (although they sometimes seem to remain quite calm), and give the same range of apparently low intensity displays as the visiting wild birds, and the captive ♂ sometimes seems to be trying to "get at" the visitors; but they don't do anything very exciting either.
   It should be noted, incidentally, that the aviary doesn't seem to be in the territory of any wild birds ―and it certainly couldn't be in the territory of all the visitors― so it is a little difficult to see what the attraction is. It may be just general gregariousness.
This species does seem to be quite gregarious in some ways. I have never seen flocks assemble, except in the cases when 3 or 4 visitors are gathered together; but it is noticeable that whenever one of the visitors flies off suddenly all the others tend to follow it ―and the captive birds try to follow too. This species does at least have the follow-the-leader tendencies of many gregarious species; (and this may also be correlated with the brilliant yellow wing patches)
    When I first got the 2 captive birds, they were put in a small cage (with the Euphorias); and I saw a couple of displays in these circumstances which I have not seen again since they were put in the aviary. There were Gaping; and an elaborate stretch (St) pattern with breast & belly feathers fluffed (BF) and Wing-fluttering (Wfl) and a peculiar soft husky call (Wh). All the latter may be included in a "Wh complex."
