Normally in our area Pied Currawongs chase the larger, but less numerous,
Greys away. Today however I watched two Pieds encouraging with urgent calls
(or were they just calling to other Pieds) two Greys who were levering off a
large patch of bark from a Eucalyptus nicholii. When the patch fell off both
Greys and four Pieds flew down and began feeding on the insects on its
underside. Throughout this the Greys ignored the Pieds.

Half and hour later the Pieds were back to chasing the Greys away.
