Cockatoos have regional accents?

["Donald G. Kimball" <>]

Hi folks:

Last Sept when I was filming Major Mitchells at Wyperfeld National Park in
Western Victoria I was very surprised to take note of their calls.  It
wasnt just one but several I heard calling that sounded dramatically
different than the ones I had filmed previously at Bowra Station.  So much
so that I knew it was a cockatoo but didnt even recognize the Victoria
birds as Majors at all.

Once I got used to this regional accent I was good to go and able to
identify them from a long distance.  Has anyone else noticed regional
differences in cockatoos calls?

Thanks!
