An adult wanderer may travel 5, 000 miles, sometimes to Brazil and back, in order to collect squid for its young.

This enormous chick weighs 10 kilos, as much as a full-grown swan. It's the biggest of any seabird chick. Although it's a couple of months before it has to face its first flight, it's now at its maximum weight. In fact, it's heavier even, haha, than... heavier than the adult. The spring snows,er, are now beginning to melt, but the chick has already faced the worst of the winter weather.

Hatched¹ last March, it has sat here on its nest mound², unprotected and unshielded for 8 months, while the temperatures may have fallen to minus 10 degrees, and terrible storms raged around. It's so big that it can't possibly grow to this very huge size in the short summer season. So the parents have to come to feed it every 3 or 4 days for 10 months. And in order to do that they have to be able to reach the open sea.

Only one other animal breeds throughout the year on the outer islands, King Penguins³. They also need continuous access to the ocean to collect food for their chicks.
