Abstract
Brent Geese migrating in spring towards Arctic Canada have been tracked by satellite from Iceland to the Davis Strait. Length and direction of the stages were adapted to the geographic features and hospitability of the areas crossed; the ice-cap of Greenland was overflown in its southern part.
Riassunto
Oche Colombaccio in migrazione primaverile verso le regioni artiche del Canadà sono state seguite via satellite dall’Islanda allo Stretto di Davis. La lunghezza e la direzione delle tappe è risultata adatta alle caratteristiche geografiche e ambientali delle regioni attraversate; la cappa glaciale della Groenlandia è stata attraversata nella sua parte meridionale.
