Marine Birds

I chose to do marine birds as my organisms because they can be found feeding off of other organisms that inhabit rocky shores. Marine birds don't get wet when they enter the water. They have a preening gland which secretes waxes and fats over the feathers to "waterproof" the bird. They also have salt glands in their body. This allows them to drink salt water, and sneeze the salt of out the water so it doesn't go into their body.
