Description
Data of snow petrel (Pagodroma nivea) of the Bunger Hills during the season 1999-2000.
During the 1999/2000 summer a group of four people visited the Bunger Hills, an area of ice-free rock situated in Wilkes Land, eastern Antarctica, with the aim of gathering scientific and other information to support the development of an Environmental Impact Assessment for the use of sites in the area for landings by large aircraft capable of intercontinental flight. The following report, which describes the natural history of the Bunger Hills, was developed from observations made in the field during this visit supplemented by information published previously. more

The snow petrel (Pagodroma nivea) is the most common bird of the Bunger Hills, with an estimated population of 1000 breeding pairs in colonies of up to 50 pairs dispersed widely throughout the southern Bunger Hills at altitudes between 25 and 155 m above sea level. About 70% of nests are located in cavities and cracks in bedrock on hills and ridges, while 30% breed under or between large boulders. Nest sites are chosen to be protected from snow accumulation and strong winds. Original data obtained from http://data.aad.gov.au/digir/DiGIR.php and registered into iOBIS on 2009-01-27. This dataset on OBIS-SEAMAP is a subset of marine mammal, seabird and/or sea turtle records from the dataset on iOBIS (Total number of records: 140) harvested into OBIS-SEAMAP on 2011-10-11.
