G'day Graeme

Thanks for your thoughts and reference to your site with calls.

Are you suggesting that the 'Western' Raven is confined to the
south-west corner and the birds elsewhere in WA are nominate
coronoides?  Looking at the BA atlas data in Birdata there doesn't
seem to be a gap along Highway 1 across the Nullabor.  Corvids are
tricky however so how many of the dots are C. coronoides and how many
are C. bennetti?  I must check my own records from our trip across in
1999 when I get home tonight.  From memory we allocated many to C.
bennetti (but I've learned to put less trust in my memory these days).

So, as you drive west and head into sw WA where do you think the
'Western' Raven first appears?  What about heading north from Perth?
