Antarctic Fur seal pup weight at Bird Island, South Georgia, from 1973 to 2020

The weight of Antarctic fur seal pups at Main Bay on Bird Island have been measured since 1973. 50 pups on the beach and 50 pups in the Tussac grass at the back of the beach are sexed and weighed in January, February and March each year.
