The razorbill is the closest living relative of the extinct great auk and breeds on UK sea cliffs, facing similar threats to other auks from oil pollution, prey depletion, and avian influenza.
Razorbill welfare reflects the health of North Atlantic marine ecosystems. Bycatch in fishing nets causes drowning. Oil spills cause prolonged suffering. Sand eel depletion reduces chick survival. Long-lived seabirds that take years to reach breeding age cannot rapidly replace population losses, making welfare of breeding adults particularly important.
