Maximum dive depths attained by South Georgia diving petrel Pelecanoides georgicus at Bird Island, South Georgia
Maximum dive depths have been recorded for a number of sea-bird species using simple lightweight capillary gauges (Burger & Wilson 1988). So far these studies have been confined to penguins (Montague 1985, Seddon & van Heezik 1990, Whitehead 1989, Wilson & Wilson 1990, Scolaro & Suburo 1991), alcids (Burger & Simpson 1986, Burger & Powell 1988, Harris et al. 1990, Burger 1991) and cormorants (Burger 1991, Wanless et al. 1991).
