The Tijuana Estuary is a small intertidal coastal estuary on the international border between California and Mexico. This place is a fantastic place for bird watching. Over 350 species of birds have been recorded in this wetland habitat. This is an important stop over for birds on the Pacific Flyway, which is a major north-south route of travel for migratory birds
