Seabirds face multiple human-caused welfare threats including plastic ingestion, bycatch in fisheries, and climate-driven prey shifts that cause prolonged chick starvation.
Seabirds face welfare threats that accumulate throughout their lives. Plastic ingestion causes progressive gut impaction, false satiety, and reduced reproduction due to malnourishment. Chicks fed plastic by parents attempting to provision them starve to death alongside adequate fish. Bycatch drowning is rapid if not rescued. Climate-driven prey shifts cause prolonged chick starvation as parents travel further for food with declining success rates. The combination of threats across long-lived species creates compound welfare impacts.
