Razorbills are closely related to guillemots and face similar welfare threats from fishing bycatch, oil spills, and climate-driven prey changes in the North Atlantic.
Gillnet entanglement causes drowning when razorbills cannot surface after becoming trapped. Longline hook ingestion causes internal injuries. Oil spill events cause rapid hypothermia. Climate-driven prey shifts force birds to forage further north of breeding colonies increasing energetic costs. Prey scarcity during breeding causes chick starvation affecting colony productivity.
