The large amounts of energy required for flight have led to the evolution of a unidirectional pulmonary system to provide the large quantities of oxygen required for their high respiratory rates This high metabolic rate produces large quantities of radicals in the cells that can damage DNA and lead to tumours Birds however do not suffer from an otherwise expected shortened lifespan as their cells have evolved a more efficient antioxidant system than those found in other animals.
Albatrosses and other seabirds take advantage of gradient of windspeeds from near the water s surface into the air Once aloft they glide with the wind gaining speed as they get closer to the water where friction slows the wind Once near the water they turn into the wind which gives them lift raising them until they reach the peak of the wind gradient At that point they turn again and glide with the wind repeating the cycle
