Something is going on?

This afternoon, the three girls and I (Ava, Ruby and Rosy) went and say out in the back yard to enjoy the sun and to let Rosy have a snuffle in the grass. Next thing I know, there are two Butcher Birds sitting very close to us and watching us like Butcher Birds do.

It was very off putting. Then a magpie swooped out of a tree overhead and landed in the carport on top of my car... the Butcher Birds were still on duty.

I didn't really like it, got a bit nervous and so went up to give some wheat to the chickens. The Butcher Birds followed us! Bizarro! They hopped up the driveway behind us...

They obviously know something that I don't know... it's definitely not chick season so it's not a nest they are protecting...?
