Yesterday, 14th July 2012, we saw and Raja photographed this juvenile mollymawk (see pictures). Although this bird has an extensive dark grey head with conspicuous white cheeks, we identified this bird as a juvenile Black-browed (or Campbell Albatross) for the following reasons:
Bill colour: horn to olive
Bill shape: relatively thick, angle of bases of upper and lower mandible quite narrow (i.e. not causing the 'glued-on effect' said to be typical of Grey-headed Albatross)
General appearance of facial pattern very Black-browed-like (especially shape of the eyebrow)
Note how the colour of the bill varies with changing light conditions!
