Southern giant petrels (Macronectes giganteus) scavenging on the carcass of an Antarctic fur seal (Arctocephalus gazella). These birds display with open wings and shrill calls throughout the feeding frenzy. This large seabird is native to Antarctica and the southern hemisphere regions. It has a wingspan of around 195 centimetres. It feeds mainly on carrion such as dead seals and penguins, but will also eat krill, squid and fish. Photographed on South Georgia.
