This dataset comprises counts of Adelie penguins attending breeding sites from images obtained with 20 remotely operating cameras across East Antarctica. Counts were made of adults, occupied nests and chicks every few days throughout the breeding season from October through to February. Locations of cameras are given in an associated dataset (Photographic images of seabird nesting sites in the Antarctic, collected by remote camera) which also provides the images obtained from the cameras. Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.

The breeding population of the black-browed albatross Thalassarche melanophrys has increased at Heard Island since the first census data were obtained in 1947/1948. Four breeding localities are known, and all populations have increased in the period 1947/1948-2000/2001. The breeding population is estimated to have been approximately 200 pairs in 1947/1948. Based on 2000/2001 census data, the population has increased to a minimum of approximately 600 pairs over the 53 years. Two mechanisms, that of increased prey availability through scavenging discards from trawlers operating within their foraging range, and climatic amelioration, are proposed as hypotheses for this increase.
