Pelicans are among the world's most distinctive waterbirds, breeding in large colonies and facing welfare threats from fishing line entanglement, habitat degradation, human disturbance at colonies, and food depletion from overfishing.
Key Facts
Eight pelican species exist globally; the American white pelican and Australian pelican are among the most widespread
Brown pelicans were nearly eliminated from the US by DDT poisoning in the 1960s-70s; their recovery after the DDT ban is one of conservation's great success stories
Pelicans breed in dense colonies; disturbance during incubation and chick-rearing causes nest abandonment, chick exposure, and mass breeding failure
Fishing line entanglement and hook ingestion are among the leading welfare problems for pelicans in recreational fishing areas
Injured pelicans frequently present to wildlife rehabilitation centres with fishing-related injuries including line wrapped around bills, hooks in pouches, and line entanglement causing wing injury
Food depletion from commercial fisheries reduces pelican foraging success, requiring longer foraging flights and more competition between individuals
Welfare Considerations
Pelican welfare is threatened acutely by the intersection of their fishing behaviour and human recreational fishing. Pelicans attracted to fishing piers and marinas by discarded bait and catch frequently become entangled in monofilament line or ingest hooks — injuries that cause prolonged suffering and often death without veterinary intervention. Line wrapped around the bill slowly strangulates the pouch; hooks embedded in the digestive tract cause internal injury and slow starvation. Colony disturbance during the breeding season causes welfare harm at scale: a single boat or hiker flushing a colony of 1,000 nesting pairs can expose hundreds of eggs and chicks to lethal heat or predation within minutes. Pelican rehabilitation is demanding but achievable; wildlife rehabilitation centres have developed effective protocols for fishing injury treatment.
What You Can Do
Never discard fishing line at fishing areas — use line recycling bins and carry all line out with you
Cut hooks off discarded bait before disposal and flatten barbs on hooks you use to reduce injury severity
Respect exclusion zones around pelican breeding colonies during the nesting season
If you see an injured pelican, contact a local wildlife rehabilitation centre immediately
Support fishing area management that protects pelicans through signage, line recycling facilities, and bait disposal bins
Donate to wildlife rehabilitation centres that care for fishing-injured pelicans and other waterbirds
