Abstract
The main goal of this project was to obtain a comprehensive overview of an as complete as possible array of available tracking devices suitable for studying the movement and behaviour of 13 different seabird species in relation to anthropogenic use of the marine environment that often attracts specific species of seabirds (buoys, platforms, fishery, ship traffic, sand extraction and OWFs). The species that are evaluated are: razorbill, common guillemot, northern gannet, great skua, Arctic skua, black-legged kittiwake, herring gull, lesser black-backed gull, great black-backed gull, Sandwich tern, common tern, red-throated diver and black tern. For the purpose of this study, we excluded geolocator and VHF-tags as possible tracking devices, as their spatial resolution is insufficient for studying offshore behaviour and movements in relation to anthropogenic disturbances such as offshore windfarms.
