Brown pelicans are frequently injured by monofilament fishing line and fish hooks discarded by recreational anglers, with rehabilitation centers treating thousands of entanglement injuries annually.
Pelicans entangled in monofilament line experience progressive restriction of wing movement, circulation loss in trapped limbs, and in cases of hook ingestion, inability to swallow prey. Birds with line wrapped around bills starve within days. The suffering is prolonged and visible — entangled pelicans are often observed at fishing piers for days before they are captured for treatment. Monofilament recycling infrastructure and angler education campaigns that reduce line discarding are highly cost-effective welfare interventions given pelican rehabilitation costs.
