On Pied Currawong

There are birds known as the pied currawong
You hear and see them once you never more get them wrong
With white tips on wings and tail and otherwise black as a crow
In South East Australia birds that everybody know
In Winter in huge flocks they congregate
And singing together a lot of sound they do create
On the tall trees that in the cool winds sway
They call out karra currawong all through the day
A bad reputation around them has grown
As nest robbers and for eating the young of smaller songbirds they are known
But on their defence it would seem fair to say
That Nature created them for to live in this way
With others birds for territory they do fight
And a huge flock of them is quite a common sight.
