Comparison of phenology of southern giant petrels at Hawker and Nelly islands over three years

The spreadsheet contains detailed information (by nest) of the timing of certain events during the breeding season of southern giant petrels (SGPs). The information was taken from images obtained from automated cameras monitoring the colonies. The numbers are 'Days since 1 June', the date chosen to indicate the start of the breeding cycle. Nest numbers were kept constant between years. Only highly visible nests were chosen. For methods and definitions see: Otovic et al. (2018) Marine Ornithology 46: 129-138.
