Over the last few weeks on my regular travels to Adelaide to attend university lectures I have observed Sulphur Crested Cockatoos on many occasions. Sometimes they are perched on the over hanging branches of trees lining the freeway. Sometime they seem to be keeping a keen eye on the flow of traffic from the vantage point of the light pole.
Most of the time they are busy feeding on the roadside verges. Their numbers can vary from a half dozen or so through to several hundred. Set against the bright green grass they make quite a sight. From time to time they tolerate several interlopers: a Corella or two or several Galahs.
UPDATE: You can buy a large range of items featuring photos of this species – and many others – on TrevorsPhotos, including mugs, tee-shirts, aprons, coasters and many more items.
