Why are southern giant petrels endangered?
On their breeding islands, Southern Giant Petrels are threatened by predation from Feral Cats and Black Rats, and by habitat degradation from introduced Caribou, Sheep and Rabbits. On some breeding islands, e.g. on the Falkland Islands, hunting has caused substantial decreases or local extinctions, (Elliot 1957; Williams 1984).
What is a southern giant petrel?
The southern giant petrel ( Macronectes giganteus ), also known as the Antarctic giant petrel, giant fulmar, stinker, and stinkpot, is a large seabird of the southern oceans. Its distribution overlaps broadly with the similar northern giant petrel, though it overall is centered slightly further south.
What predators do southern giant petrels eat?
Southern Giant Petrels are also an active predator of cephalopods and euphausiids, as well as smaller birds (particularly penguins) both at land and at sea. Although representing a small proportion of its total foraging area, potential forage in NSW waters during the winter is nonetheless considered significant for the species.
What is the average age of breeding for the southern giant petrel?
The southern giant petrel achieves sexual maturity at six or seven years of age; however the average age of first breeding is ten years. Its breeding season begins in October.
