Long-term population increase of black-browed albatrosses Thalassarche melanophrys at Heard Island, 1947/1948 – 2000/2001
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 es...
