These Sulphur Crested Cockatoos are all wild birds. I live on the outskirts of Sydney near bushland where these cockatoos live in large flocks. They are very playful birds and these photos were mainly taken in my front garden where they often stop off on their way to the nearby golf course to drink at the lake. There are several local flocks that appear to have a few hundred birds in each flock. They sure do brighten up a dull day. They are often joined by Galahs, Long-billed Corellas, Little Corellas and Rainbow Lorikeets.
