Puffin population monitoring through citizen science programs provides welfare-relevant data on breeding success, chick survival, and prey availability.
Puffin colony monitoring provides welfare-relevant data that informs conservation management. Chick weight monitoring reveals nutritional welfare — underweight chicks indicate prey shortage and predict mortality before visible clinical signs appear. Observation of fish species delivered to chicks shows whether nutritious sand eels are available or being replaced by less nutritious alternatives. Long-term data enables detection of trends that might be invisible in any single season. Citizen science approaches that train volunteers to conduct standardized monitoring generate data at scale impossible for professional researchers alone, making it one of the most impactful contributions available to wildlife welfare advocates.
