The Kerguelen Petrel (Lugensa brevirostris) is a small (36?cm long) slate-grey seabird in the family Procellariidae. The species has been described as a "taxonomic oddball", being placed for a long time in Pterodroma (the gadfly petrels) before being split out in 1942 into its own genus Lugensa (or Aphrodroma).
