A groundbreaking doctoral study by Cassandra Ugland from the Norwegian University of Science and Technology (NTNU)’s Department of Biology has uncovered that young European shags make critical migration decisions based on their first winter experience. Published in the Journal of Animal Ecology, the research reveals that birds exposed to harsh conditions during their initial winter are more likely to migrate south in subsequent years, while those with milder winters tend to stay put.
The findings highlight how early life environmental stress shapes long-term behavioral patterns in migratory species. With data collected across key breeding sites in Norway and the North Sea region, the study underscores the ecological significance of climate variability on avian survival strategies.
