On Hearing Long Bill Corellas

To their roosting trees in the townpark they call out as they fly
A large flock of long bill corellas in the darkening evening sky
At least one hundred of them for to roost they congregate
A group of them together a lot of sound create
That they are not very plentiful to say the least seems strange
As they are birds not known to have an extensive range
Unlike the short bill corellas, galahs and sulphur crested cockatoos who do range far and wide
The long bill corellas restricted by their choice of countryside
Like all cockatoos they brood their eggs in an old tree cavity
And out of breeding season in large flocks one them often does see
They are not quite so plentiful as they do seem to be
As they only live in a small part of Australia's huge Country
I hear them in the twilight sky in the fading evening light
As they fly to the town park trees for to rest for the night.
