Foraging ranges of incubating sooty terns onychoprion fuscatus on Bird Island, Seychelles, during a transition from food plenty to scarcity, as revealed by GPS loggers
The foraging tracks of incubating Sooty Terns, nesting on Bird Island, Seychelles, were identified using GPS loggers attached to the central pair of rectrices. By chance, our 2014 study covered a transition from food abundance to food shortage. Incubation shifts during food abundance were mainly 1-2...
