Kookaburras attacking the house

A few days ago a pair of Kookaburras started attacking an old steel air conditioner on the side of the house. They sit on a branch and take turns flying right at the thing, hitting it hard with their beaks. It makes a loud clang, sometimes they get their beaks stuck between the slats.

These are the 2 kookaburras that have been attacking the side of the house for the past few days. Don’t know why they’re doing it. They’re hitting an old steel air conditioner really hard with their beaks, sometimes their beaks get stuck between the slats
