I have been doing research on ARBs for a year now (I do a couple of hours of research almost every day) but found one single reference of the small flocks you mentioned -although they said four birds of the same family- and it wasn't a reputable one at that. That's why I was asking for yours.
I am sure that your observations are correct but, in my personal experience and for what I know about field biologists work, observing a single individual of a species tells us more about the individual bird than the species in general. Parrots have such distinct individual personalities and quirks that one would not know if what one is observing is a generic species behavior or an idiosyncrasy of the bird we are watching. For example, my experience is completely different from yours. I've had four senegals, one male and three females, and although the male was a holy terror when he first came, he no longer bites (he is now on my lap, pushing his head against my elbow asking for head scritches) while the hens were all three the sweetest, sweetest things to me (never a single bite) and they all liked going to ground all the time- so much so that this has become a problem with the male because I have to constantly tell him to get off the floor. On the other hand, I've never ever seen Isis, the ARB, on the floor, her 'thing' is to fly around, up and down the stairs from the first to the third floor and has her favorite 'perching spots' on each floor but all of them are high (the top of the cardinals cage in the living room, the top of the door between the canary room and the kitchen, the top of the fridge in the kitchen, the frame of a picture my husband has in his study so she can chew it up, and, on the second floor, the shower curtain rod in the bathroom, the top shelf in the dressing room and the rail of the stairs). But, in all honesty, I can't really give an opinion on ARBs behaviors because I only have the one female and, again, if I went by her, my conclusions would be the opposite of yours because my senegals seem to be much fiercer than her -especially my female which I have to watch like a hawk or she will pick a fight with the ARB given half a chance -and win even though she is smaller! And my GCC hen would not only confront her but also make her back up whenever she tried to bully Pablo, her handicapped boyfriend... I guess my Isis is a bit of pushover compared to your redbelly
