Foraging strategies of breeding seabirds studied by bird-borne data loggers
Our research group has devised and manufactured a data logger, which, glued on the back of a bird, can detect and memorise the direction in which the bird is heading during a flight. Given the birds' constant cruising speed, the memorised data can be used to reconstruct the whole flight path. S...
