Well if you are not a West Australian you may be scratching your head on this podcast name!  What on earth is a Naso?  The name comes from the birds scientific name - Calyptorhynchus banksii naso - a black cockatoo species described by the famous English birdman John Gould; he chose this name in reference to the bird's large bill.  
The Naso is an Australian black cockatoo that lives in the far south-west corner of Western Australia.  This bird is also called the forest red tailed black cockatoo, as it lives and feeds in the eucalypt forest endemic to the south west corner.
Sadly this cockatoo is under serious threat of extinction (like so many birds) and is given a suitable listing to reflect it's status in the wild by the WA state government.  There was once large flocks of the Naso but sadly with human endeavours such as logging, agriculture and clearing, along with  natural disasters such a bushfires, this bird is struggling.
The Naso is an incredibly noticeable bird; it is showy and loud.  You couldn't miss hearing it if you wanted to!  So although Birdman Dad has seen the Naso in wildlife parks and in people's aviaries (helping protect the species DNA survival) he wanted to see the Naso for himself in it's homeland.
Truly a beautiful bird and a real joy to hear as you walk way down on the forest floor.
