Studying the at-sea movements and behaviour of juvenile seabirds is logistically challenging, but new technologies now allow tracking birds on their first migration, giving a more complete picture of population-level spatial ecology. We investigated the post-fledging migration of juvenile northern gannets Morus bassanus from the world's largest colony, at Bass Rock, Scotland. We first examined the movements and survival of 38 juveniles over their initial days at sea with GPS precision for up to 53 d post-fledging. We then compared their migration journeys with those of 35 adults tracked with geolocators.

Dans le cadre du programme européen Interreg Samarch, une équipe de l’Agence française pour la biodiversité prévoit de suivre les déplacements de poissons migrateurs. Les premiers résultats du terrain valident le protocole de détection et de capture-recapture des poissons concernés.
