　　The professor talks about two special adaptations developed to help seabirds find food. The first adaptation is the Length of wings. Usually, when birds fly, they have to flap wings up and down and uses a lot of energy. But albatross, a kind of seabird,has specially long wings that enable it flies without moving wings up and down.So it can glide and float on the wind using little energy. This is so because albatross has to cover huge expanse of ocean to locate food. Another adaptation is a cute sense of smell. Fulmar also has to find food scattered in the ocean and its main source of food is tiny plankton. Fulmar develops tiny tubes inside nose hole and the special tube-shape no strils help them to pick up the scent offood. Plankton is hard to see but it gives sharp distinctive odor. So Fulmarcan find plankton by smelling them even from far away.
