The use of drone-based aerial photogrammetry in population monitoring of Southern Giant Petrels in ASMA 1, King George Island, maritime Antarctica
Southern Giant Petrels (SGPs) are surface nesting birds with a circumpolar Southern Hemisphere breeding distribution. The species tends to have no natural enemies on land, but is sensitive to human disturbance. The search for new methods is crucial and may minimize or exclude stress and risk of nest...

Southern Giant Petrels (SGPs) are surface nesting birds with a circumpolar Southern Hemisphere breeding distribution. The species tends to have no natural enemies on land, but is sensitive to human disturbance. The search for new methods is crucial and may minimize or exclude stress and risk of nest disturbance, related to ground-based research activities. The aim of this study was to conduct a population census of the SGP of the Antarctic Specially Managed Area no. 1 (ASMA no. 1), Admiralty Bay, King George Island, using an unoccupied aerial system (UAS) based on aerial photogrammetry and to determine the optimal parameters of the aerial mission for the identification of SGP adults and chicks on orthophotos while simultaneously not causing behavioural changes. To this end, in a preliminary survey in the 2019/20 season, the locations of all breeding areas for SGPs in ASMA no. 1 were determined, and the presence of 3 colonies, Llano Point/Rescuers Hills (LP/RH), Vaureal (V) and Petrel Hill (PH), was confirmed. Terrain models for two of the colonies (LP/RH and V) were established, and the flight parameters for the next season were determined.
