Snow petrels are among the hardiest seabirds on Earth, nesting deep in Antarctic rock crevices, but face welfare challenges from extreme weather events, pollution bioaccumulation, and climate change impacts on sea ice.
Snow petrels face welfare challenges primarily through the indirect effects of human activity on their isolated Antarctic environment. Climate-driven sea ice loss reduces the abundance of ice-associated prey, forcing birds to travel further and expend more energy finding food during the critical chick-rearing period. Chicks that receive insufficient food suffer from nutritional deprivation in an environment where cold stress is ever-present. Pollution bioaccumulation reaches even these remote birds, with potential immunological and reproductive consequences.
