Subject: Re: Brown Booby more
As I understand it, the paler head only applies to males of Cocos. The
eye seems pale which might be an argument against Cocos. But it might be
a bit more complex since this is a young bird. It would also seem a good
idea to bear in mind that Brown Booby was split into 3 by Howell and
Zufelt, and you never know what might happen in future! But I assume if
not Cocos then the Atlantic form would be the most likely.

Right now there is a Cocos attracting a lot of people in Australia,
where it will presumably be the first documented occurrence!

Chris.

The rounded point directly in front of the heart sculpture is his favorite spot. He returns to it and is found their most often.
