Distribution. Antarctic Seas. 
Adult. Upper-surface dark bluish-grey ; chin, throat and sides of the face blackish ; remainder 
of under-surface silvery-white ; wing like the back, edged on the inner side with white, 
under-surface white with the upper edge and tip bluish; tail of fourteen feathers ; eyes 
brown ; bill reddish ; feet flesh-colour. Total length 610 mm. : culmen exposed 30, 
from gape 52, wing 190; tarsus 25, tail 155. 
The sexes are alike. 
The immature have the chin and throat white. 
Chick in down, uniformly dark and sooty. The changes undergone as the nestling grows shows 
that the colour of the head is in all cases somewhat blacker in the earlier stages than the 
remainder of the body. But this difference gradually disappears, owing no doubt to the 
change in the nestling’s down. 
Nest. A ring of stones varying in size according to the owner being a good or bad “ getter.” 
Eggs. Clutch two (three days elapsing between the laying). In shape they are equally rounded 
at either end. The outer texture of the shell is chalky and under this is a green colour 
which by transmitted light is very marked. 64-72 by 50-55 mm. 
Incubation-period. 31-34 days. 
Breeding-season. End of October to beginning of December.
