This is a short clip showing two of the birds who call our place home arguing about who owns 'my' wool basket. They are both from the Corvidia family; a currawong (big black one) and a butcher bird (grey scale one) and so are about as smart as the average 5 year old. We raised both of them and they have both spent considerable time in the wool basket as chicks.
All our animals (kids included) go through a 'we don't hit' learning phase where we show them it isn't acceptable to be violent in the house, that way there is a safe zone for everyone even natural enemies like these two.
You can see them both asserting their right to the basket but being too polite to fight because I am there. They sometimes roost together in the house so are not really enemies, although their species usually are. Things will probably change when they both have children (you know what that's like).

Pew (the currawong) has left home and joined a gang of juvenile currawongs although he still spends about one day a week at home. We expect that to change when he gets a steady girlfriend and hope he doesn't bring the grandkids home for baby sitting too often.
Roadie (the butcherbird) is hunting for himself and doesn't need help with anything. He still sleeps inside (its Winter and the stove is warm) on a high perch and relies on us for affection (play and cuddles) but that will change in the Summer when he starts to look for a mate. Being a member of a solitary species, he won't join a gang but will find a single girl and settle down for life.
With wild birds there is always a risk of over-humanizing (and who wants more of them) but the risk is fairly low with the corvid family, thanks to their intelligence.
The galahs on the other hand......well that's a story for tomorrow.
