Yellow Tailed Black Cockatoos

The big dark brown parrots known to most as yellow tailed black cockatoos
Though some do refer to them as the weerloos
In small flocks distinctive from other parrots in every way
Birds i do see often though not every day
To crack hard hakea nuts they must have strong beaks indeed
And often seen on monterey pine trees shredding the pine cones for their tiny dark seed
High in a tree cavity two pale eggs the female bird does lay
But only one of the young survive to adulthood this is their natural way
In Nature quite often for the strong to thrive
The weak in many cases not destined to survive
Among the slower birds of flight of the sky
In small flocks they call out wee yu as they fly
Quite beautiful birds with ways of their own
In their range known to many and to many well known.
