On A Question Of Long Bill Corellas

He asked me why long bill corellas call out in the sky
High above the town in large flocks as they fly
My ignorance on this i did not even attempt to deny
I answered his question with an i do not know why
Long bill corellas behave in  such a way
Though i see them and hear them calling every day
On tall trees in the park or above the paddocks by the town
To flock in large numbers one of their claims to bird renown
But one thing of long bill corellas i have come to know
That within their small range their flocks in numbers do grow
But due to smaller living territories they remain on the protected list
As those who know far more about birds than i do insist
That on the protected list they do stay
These birds i know of and see and hear every day.
