2. Characteristics  No real physical distinctions between sea birds and other birds such as wing shape, because each species has evolved differently to survive.  Adapted to survive in areas with salt water.

3. Diet and Feeding  Surface feeding  Pursuit diving  Plunge diving

4. Surface Feeding  Can be done while flying, or floating on the surface.  Birds often have specially adapted bills to filter out plankton.

5. Pursuit Diving  Often use wings to propel themselves into the water.  Exerts more pressure on the bird, but with better reward.  Often used by penguins.

6. Plunge Diving  Dive from flight directly into the water.  They use momentum to dive farther than they could normally because of buoyancy.  They begin their dive from about 20 meters above the surface.  http://www.youtube.com/watch?v=pWFb vbMMSV0 http://www.youtube.com/watch?v=pWFb vbMMSV0
