Saunders Island is the second largest offshore island in the Falkland Islands (Islas Malvinas)*.  It is located in the north-west of the archipelago, comprising an area of 132 km2 and a coastline of about 100 km in length.  The island consists of three peninsulas linked by narrow necks, with extensive upland areas.  Saunders is privately-owned and is run as a working farm with sheep, cattle and horses.  It is a popular destination for both day and overnight visits.

It suffers from the presence of several introduced mammals: rats, mice, rabbits and cats.  The Neck, located on a narrow isthmus of sand, is a favoured destination for tourists, combining scenic beauty with an abundance of wildlife, including Black-browed Albatrosses Thalassarche melanophris that breed nearby.

Saunders Island is one of 12 breeding sites for Black-browed Albatrosses in the Falkland Islands (Islas Malvinas)*.  The albatross colonies are spread along the northern coastline of the island, and are often associated with stream beds or gulches that provide mud that is used for nest building and maintenance activities.

The island supports in excess of 10 000 breeding pairs of Black-browed Albatrosses, with an aerial census in 2010 recording 16 722 pairs compared with 13 053 pairs recorded during ground surveys made later the same year.  As with most other Black-browed Albatross breeding sites in the region, the population has been increasing in recent years.

On account of its Black-browed Albatross population and other breeding seabirds, including Gentoo Pygoscelis papua, Southern Rockhopper Eudyptes chrysocome and Magellanic Spheniscus magellanicus Penguins, Saunders Island is an Important Bird Area (IBA).  It is one of the few sites in the Falkland Islands (Islas Malvinas)* where one may be able to see five species of penguins breeding: Gentoo, Magellanic, King Aptenodytes patagonicus, Southern Rockhopper, and Macaroni E. chrysolophus, the last sometimes breeding within Rockhopper colonies.

Although ACAP-listed Southern Giant Petrels Macronectes giganteus do not breed on Saunders Island, there is a small colony (c. five pairs) on Burnt Islet, just to its south.
