Field notes

  • It is one of the few petrels that breeds during the austral winter, arriving at nesting colonies as early as February.
  • Remarkable for its diving ability among procellariids, it can reach depths of nearly 10 meters to capture prey.
  • The species is frequently nicknamed the 'Pediunker' by sailors, an onomatopoeic name reflecting its distinct call.
  • It is highly susceptible to longline fishing bycatch, which has contributed to its status as a Near Threatened species.
  • Unlike many related species, it tends to nest in burrows situated on well-drained, vegetated slopes rather than flat ground.
Habitat
Pelagic open waters and sub-Antarctic island coastal slopes.
Range
Circumpolar throughout the Southern Ocean, typically between 32°S and 58°S.
