So the hollows in trees don't always come easy?

I've read it usually takes a hundred years before a gum can develop the kinds of hollows required for breeding by many native birds and animals, which is one reason old trees are important. In this instance a hollow already existed, but the galah was determinedly improving on it. Maybe this is why galahs and parrots need such strong beaks and claws.

    Yes I've wondered when you watch them eating dandelions which wouldn't obviously need such strong implements.

    All the better for destroying orchards!

    Their claws and beaks are a kinda overkill for dandelions and grass seeds but they eat tough food too, such as the casuarina seeds, or at least some of the cockatoos do.
