At low tide, there's mud as far as the eye can see. At high tide this is all water. The semiplamated sandpiper migrates to the Bay of Fundy during August to feed on a very small mud shrimp about the size of a grain of rice. The females come first and eat thousands of these little shrimp during a 2 week period before they migrate to South America. The males come next for 2 weeks and then the chicks. They fly totally across the ocean before they land in South America.
