Up ahead the noise and odor of the Black legged Kittiwakes will soon become apparent. These birds take advantage of the slight depressions in the rocks to build their nests. Their nest is simply some grass and mud glued to the rock wall with their own guano. These birds nest in dense aggregations as a means of protection against birds of prey.
If a Bald eagle or Peregrine falcon flies into the area every bird will leave the rocks in one downward swoop. They do this to confuse the birds of prey by sheer numbers. Kittiwakes, unlike puffins will lay 3 eggs most seasons, their strategy gives them more room for error. If one chick perishes there are two others that may survive.
