The Falkland Islands, a British overseas territory in the South Atlantic Ocean near the coast of South America, is home to several unique indigenous bird species. One of them, Catharacta Antarctica, also known as the Southern Skua or the Falklands Skua, is in serious decline. Over the past five years, their population has gone down almost 50 percent. The exact reasons are unknown, but some experts suspect the decline is due to low breeding success and increased competition for resources. Some fear that the problems with the skua are linked with an unhealthy Patagonian marine ecosystem.
