Wandering albatross: Is foraging efficiency a key parameter in aging?

The male wandering albatross, which can live more than 50 years, modifies its foraging behavior with age. Researchers in France have, for the first time, shown such changes by studying aging in these birds under natural conditions. The scientists have discovered that old males forage in different waters from younger males, and are less active at the sea surface. However, none of the classic markers of human aging are altered in old albatrosses, which underlines the importance of taking account of foraging efficiency in studies on aging.
