Currawong and the Bark

I hear a rustling in the Galinyala Port Lincoln mallee trees and look up to see a currawong in the top branches pulling away a strip of brown bark to release something that had been slightly deeper inside. What it is I cannot see, but he gets his beak in there, spearing around, like a finger, trying to locate it. Currawong in the morning mallee tree, rustling and reading the bark like paper.
