Comparative ecology of the six albatross species breeding on the Crozet Islands
Six species of albatrosses breed sympatrically at the Crozet Islands. The population size, masses and measurements of adults, nesting habitats and coloniality, laying, hatching and fledging dates, duration of incubation and brooding shifts are compared. The growth of chicks, diets and feeding method...
