Albatrosses are the most efficient travelers of all vertebrates on the planet. They expend zero energy soaring hundreds of miles over the ocean each day using dynamic soaring and slope soaring. They have a tendon in each shoulder locking their wings fully-extended, so once aloft and soaring across a fair breeze they never need to flap their wings. Like some vultures they hunt by smell, sensitive to the odor of carrion and other biological processes.
