First documented record of barn swallow (Hirundo rustica) in the Antarctic

First documented record of barn swallow (Hirundo rustica) in the AntarcticHere we report a photo-documented record of a barn swallow (Hirundo rustica) from the South Shetland Islands. We also review previous records of passerine vagrants in the Antarctic (south of the Antarctic Convergence Zone). This barn swallow is the first recorded member of the Hirundinidae family on King George Island and is only the second passerine recorded in the South Shetland Islands. This sighting, along with previous records of austral negrito and austral trush represent the southernmost sightings of any passerine bird anywhere in the world.
