冰川海洋上的鳥兒~ Hints： petrel vulture crumb Antarctic scavenger wandering albatross updraft South Georgia

They are the crumbs left behind after a catch by killer whales. Giant petrels, the vultures of the Antarctic, soon dominate the feast.
The biggest of all the scavengers is the wandering albatross. With a wingspan of over three meters, this bird can range over greater distances than any other. It needs the updraft created by waves in order to fly, and only these stormy southern waters provide that in such abundance . Throughout the winter, wandering albatross remain in the south, for although the continent is trapped in ice, there are a few outer islands that always remain beyond its grasp, and these provide the albatross with their nesting sites.
Three thousand pairs of wandering albatross nest on one of them, here in South Georgia.
