Janine,

Nice! At least image 4 shows a Carnaby's Black Cockatoo.

Cheers,

Nikolas

Hi all

We saw an enormous flock (at least 500, I estimated 1000) white-tailed 
Black-cockatoos flying across the highway in Yanchep NP on Friday 22nd 
June at around 3.10pm.  I have a few photos, which suggest Carnaby's, 
but I also have calls recorded which suggest Baudin's.  The call has a 
high-pitched whistling quality - more of a "wa - witch-ow!" than a 
"wy-lah".  Listening to both species' calls on the Morcombe Iphone app 
today still left me in some doubt - the flock call of the Carnaby's is 
possible (and this was a huge flock), but most of the calls I recorded 
were of single birds or pairs that had stopped near us.  Also, some of 
the birds were seen tearing at the bark of rough-barked eucalyptus trees
 - a habit noted for Baudin's (according to Simon Nevill's Birds of the 
Greater South West.)  

Here is a link to a Picasa album with the best photos I have: 
https://picasaweb.google.com/112756569112498336946/PicsWAJune2012 ; 
Please forgive the poor quality of the photos.  I can't figure out a way to 
upload the sound recordings, but I can email them to anyone who 
wants them. 

I know the location strongly suggests Carnaby's but the call is really 
giving me trouble.  Being from Melbourne I really don't know these birds
 at all. 

Janine
