from finding a bug can't possibly be greater than the energy the expend doing all of that pecking.

I don't understand where all of their energy comes from.

It flies from one of our trees to the neighbor's tree and then back to ours. It woke up our daughter at 5 a.m.

They're illegal to shoot where we live, but I've got a high-powered pellet gun and wouldn't give a second thought to plunking it if I could see where the dumb thing is.

Carry on. Have a nice Sunday.
