A bunch of Brown Skua, a seabird that appears a bit like a cross between a typical gull and a Big Petrel, have been discovered to have the virus on Fowl Island. Fowl Island is a British territory belonging to the South Georgia and South Sandwich Islands. Brown Skuas are migratory, so it’s believed that the virus could have been carried in from South America, an space the place seabirds and mammals have been arduous hit by HPAI.
This discover is troubling for a number of causes. The primary is that it demonstrates the unbelievable attain that avian influenza has achieved.

From albatrosses to penguins to geese, an outbreak on the islands has the potential to be devastating each to the inhabitants of grownup seabirds and to the success of their breeding season.
With the current discovery of Fowl Flu on Fowl Island, the security of each migratory and remoted Antarctic chicken populations could also be in danger.
