Thanks Chris,

As a result of my request, the report with the photo has been taken off Eremaea 
now. The other report of a Grey-headed Albatross (two other observers) from the 
same spot and same day is still on Eremaea. Not sure if they were referring to 
a different bird.


Yes, Chris, also in my experience the eye-patch of a young Campbell Albatross 
(2nd year, but also possibly 1st year) is very different from that of an adult 
Campbell Albatross and looks more like some smudged make-up. To me the 
eye-patch appears cleaner in Black-brows of the same age. But again, this may 
be very variable and I haven't seen any peer-reviewed evidence supporting that. 
The 'thing' on the link you are referring to looks like an adult Black-browed 
Albatross with an extreme eye-brow somewhat reminiscent of that of an adult 
Campbell Albatross.

Cheers,

Nikolas

Certainly looks like a Black-browed to me.

>From what I remember, the eye-patch difference between melanophris and 
impavida is apparent at a young age, long before the eye-colour means 
anything. So I'd go with melanophris.

Then again, what is this thing?

Maybe the eye-patch is more variable than I thought.....

Cheers, Chris.
