Lonesome Cockie

The big Sulphur Crested Cockatoos descend on our place in a flock at Walnut Time. Only then..........we never see a single one at any other time of the year. They appear from nowhere. Hang out in the big Pine Trees in the paddock, then silently swoop into the Walnut Tree for a feed.
This year however we have one that keeps coming back! Just one little Cockie who waddles around the garden eating the few remaining walnuts on the lawn. (the Tree itself is long empty).
You have to wonder why? Is he an escaped 'pet' one? Has he been disowned from his flock? Does that happen? Or is he an exceptionally smart one who knows he is on to a good thing? We shall never know but we will enjoy his little visits while we can!
Apologies again for another magnificently bad quality Australian Wildlife photo!
