Cockatoos are indelibly linked to the Australian outback, often through popular image culture, and this popular photography subject has indeed proven in recent times that cockatoos reside not only in the bush, but are also moving into many of Australia's bigger cities and towns (check out Cockatoo Wingtag - Big City Birds).
As these big white cockatoos become part of Australia's urban landscape, the average Aussie is misled into thinking that all theses big white cockatoos are all the same and belong to all the same family. 
The big white cockatoos with the yellow crest is known as the sulphur crest; scientific name Cacatua galerita galerita; and this is known as the nominate race.  The C.g.galerita lives over much of Australia. But like so many Australian parrots,  what you think you see, is not always what you think you are seeing.. in the case of the sulphur crest cockatoo, there is in fact 3 types!
Today BirdCast is chatting with Stephan Maric, who is a birdkeeper and bird lover living in Melbourne, Victoria and is one person who knows a lot about the C.galerita.galerita and C.g.fitzroyi - aka Fitzroy (or Matthews) sulphut crested cockatoo.  Stephan shares a wealth of knowledge about caring for the Australian cockatoos in your life and is a living advert for the value of bird clubs - if you know the Health Department adverts of Act, Belong, Commit - you will understand Stephan's passion for the bird club he belong to - The Avicultural Society of Australia.
The photographs Stephan mentions in the podcast will be shared on our instagram page and on the #100parrots Project page - be sure to check them out!
