There are 125 species of tubenose birds, which include the petrels and albatrosses. The four species illustrated on this set of stamps represent three species of fulmarine petrel and one species of diving petrel. These birds inhabit an oceanic environment, feeding on the abundant food supply present in the Southern Ocean. They nest and breed on many islands in the Southern Ocean, including South Georgia, the three species of fulmarine petrel also breed on the South Sandwich Islands.
Three of the original paintings making up this set of stamps will be on display at the 'Artists for Albatrosses' exhibition, at the Air Gallery, Dover Street, London, 5-15th October 2011. The exhibition is raising funds and awareness for albatross and petrel conservation.
