Butcherbirds and Chain Saws

It has been quite some time since Pied Butcherbirds have come to investigate a possible snack when I have been cutting wood.

The first I knew the Pied Butcherbirds were about was when I was cutting something flashed past in the corner of my eye and landed in a tree near me.

Hanging on no matter what the size of the tree is to look around the cutting site.

On the end of the log you can see among the already cut rounds of timber, hoping an insect will scurry about.pied butcher bird05_chain saw_named_home_july 2018
These two looked in the bark that I stripped from the log so the chainsaw would get blocked with the fibres from the bark.pied butcher bird03_chain saw_named_home_july 2018

I think they may have found a few insects. Under the bark were some wood cockroaches hibernating. It took a while for the wood cockroaches to think about moving when I first pulled the bark back.pied butcher bird04_chain saw_named_home_july 2018

Overall there was four Pied Butcherbirds rummaging in the bark and the cut pieces of tree. They never sat close enough to get all four in the one photo. The last time the sound of the chainsaw bought Pied Butcherbirds around was over ten years ago. I wonder where they have been?
