With nearly 490 species recorded (45% of species of birds in North America), Point Reyes National Seashore easily claims the prize for the greatest avian diversity in any U.S. national park. The species total here, in fact, is larger than the species total in each of forty of the United States! The optimal latitude, diverse habitats, stopover on the Pacific Flyway, and geographic magnet of the peninsula are responsible for attracting this amazing diversity.
