Eggs and chicks can fall prey to birds, such as the sheathbill and the brown skua.
On average, a skua is about 56 cm (22 in) long, and 121 cm (48 in) across the wings.
The perceived decline may be due increased predation from gulls, skuas and introduced mammals.
These nesters include species of albatrosses, petrels, skuas, gulls and terns.
This would affect the population of penguins, petrels, albatrosses and skuas.
At one time the great skua was extremely rare in my constituency.
The same is true of the petrels, the skuas, the terns, and many of their eggs make quite delicious eating.
I need not stress that we are also concerned with other animals and wildlife, particularly birds such as the albatross, penguins, petrels, skuas and fulmas.
