Hi Peter,
We are on acreage 35klms N of Brisbane. When I feed the dogs each evening the magpies, Kookaburras and Grey Back Butcher Birds all join in.
The pecking order is complex. A Kooka is above a Maggie. Two Maggies top a Kooka. There are squabbles every feed time. The Butcher birds are small and agile. Fly in very quickly and make a quick getaway with the prize.
I started feeding the Maggies initially to stop F-one-eleven (F111) from swooping me. It worked. Each spring the Magpies have new offspring. They join in for 9-10 months and are kicked out. Allowing room for the next ones.
Some have learnt that taking food from my hand is an effective method to avoid confrontation with the other birds.
Under the trees I place seeds. That attracts many different parrot varieties, including Cockatoos.
Cheers Marty
