In the waters off South Africa, albatross chicks face a deadly threat from trawler cables, killing up to 14,000 birds annually in the country and 700,000 seabirds worldwide. BirdLife South Africa’s bird scaring lines have cut albatross deaths by 99%, a major conservation success. A new sensor now ensures they're actually being deployed, helping fisheries maintain sustainability standards. Yet globally, most albatross species remain endangered.
