Brown and white pelicans face ongoing welfare threats from fishing line entanglement and hook ingestion that cause wing injuries, foot damage, and starvation requiring skilled rehabilitation to address.
Pelicans entangled in fishing line experience progressive suffering - the line tightens as the bird moves, cutting off circulation and causing tissue death over days to weeks before the bird is found. Swallowed hooks cause internal pain and prevent feeding. The scale of entanglement mortality in fishing areas with high pelican populations represents a preventable welfare burden - every piece of monofilament properly disposed of eliminates a potential entanglement hazard that persists for years in the environment. Rehabilitation programs address individual welfare but cannot substitute for prevention at scale.
