Advanced welfare science for barn swallows integrates physiological indicators, behavioural assessment, and ecological monitoring to provide comprehensive welfare evaluations informing conservation management.
Advanced welfare science for barn swallows applies biomarker approaches originally developed for mammalian welfare research to this challenging study species. Telomere length and feather corticosterone provide retrospective welfare indicators that complement behavioural observation. This scientific foundation enables more precise welfare assessment and management recommendations for populations in different habitat quality contexts.
