To evaluate the generality of this effect in large gulls, we investigated the reproductive performance associated with the same type of GPS-mounted system in four Mediterranean breeding colonies of the Yellow-legged Gull Larus michahellis in 2022. We found no significant difference in reproductive parameters among adults handled with a mounted device, adults handled with no device, and controls, and no interaction with colony of origin. The impact of the GPS harness system on short-term reproduction is therefore not generalizable among larid species, and should be tested and reported whenever a new tracking programme is employed.9 p.application/pdfengcc-by-nc (c) Souc, Charly et al., 2024http://creativecommons.org/licenses/by-nc/3.0/es/Ocells marinsSeguiment biològicBenestar dels animalsReproduccióSea birdsBiological monitoringAnimal welfareReproductioninfo:eu-repo/semantics/article7489542025-03-24info:eu-repo/semantics/openAccess
