SHY ALBATROSS Diomedea cauta


SHY ALBATROSS Diomedea cauta
White-capped Albatross
L 96–100 cm, WS 198–256 cm.

IDENTIFICATION 
Vagrant from Southern Oceans. Slightly larger than other mollymawks, but size difference unlikely to be of use in our region. Often follows ships. Adult distinguished by distinctive underwing pattern with very narrow black border to white wing and small but distinct black patch, or ‘thumb mark’, at base of leading edge which projects into coverts (visible at quite surprising distances if one is looking out for it); also by pale yellowish-grey bill with yellower tip. 

Head of nominate race is white (with grey cheeks, not easily visible). Juvenile distinguished by underwing pattern (see adult) and by pale bluish-grey bill with black tip. Head grey. Immature often shows white head with partial darkish collar and juvenile bill pattern; best distinguished from juvenile/immature Black-browed by underwing pattern. 

VOICE 
Usually silent at sea.
STATUS/HABITAT 
Vagrant (Eilat, Israel; nominate race). Away from breeding colonies pelagic, only locally coming close to shore.
