We met some problem to the identification.   Share with you all.  Below are two pictures of crow which took in Hong Kong. Both of them have powerful bill, but the shape of the foreheads and the bills are completely different. I would like to seek on identification:   1. Are they the same species? 2. Is there any sub-species occur in Hong Kong?     Please help. « Last Edit: May 28th, 2004, 1:58pm by BBS Moderators » Logged Mike Kilburn Guest Re: Large-billed Crow? ! Please help... « Reply #1 on: Oct 7th, 2003, 9:47am » Quote Modify Remove Hi ???   They are both Large-billed Crows.  The upper picture shows a typical adult bird with the typical steep angle between the bill and the crown.   The lower one is a juvenile. They show the shape of the skull much more clearly and do not have the full feathers on the crown.   However you ned to wacth out for Carrion Crow. There are less than 10 records, but thay also show the flat crown like the juvenile, but the bill is more slender.   Cheers   Mike   Cheers   Mike     Logged 假鳥迷 BBS Member BBS God Have fun...     Posts: 112 Re: Large-billed Crow? !
