Résumé :	Avian flight heights are currently a focus of interest in terms of assessing possible impacts of offshore and inland wind farms on birds. We therefore analyzed the flight-height distribution in a tracking study of foraging Lesser Black-backed Gulls (Larus fuscus) on the southern North Sea coast during the incubation period. We distinguished between marine and terrestrial, nocturnal and diurnal, straight and tortuous, and outbound and inbound flights. Individuals were equipped with specifically programmed GPS data loggers to ensure accurate flight-height measurements. A total of 89 % of recorded fixes were below
