Pelicans face persecution from fisheries, entanglement in fishing gear, and habitat disturbance at breeding colonies across their global range.
Fishing line entanglement causes prolonged suffering with hook injuries to the mouth, esophagus, and pouch. Monofilament line wrapping around bill or body causes slow strangulation. Persecution through shooting and poisoning by aquaculture operators causes direct suffering. Nesting colony disturbance causes mass chick abandonment with starvation following.
