Most of the birds found in the park and parkway are migratory, spending only 3-6 months here each year. Migratory birds are protected while they nest in national parks, but may lose safe nesting sites on other lands due to human activities. Migratory birds also face numerous perils on their long journeys to and from wintering grounds. Human-caused habitat changes fragment forests and remove safe feeding and roosting areas in migration corridors. Birds that migrate to the tropics may lose their winter range due to deforestation. Birdwatchers and scientists alike have become concerned about the future of migratory birds. Show your concern by enjoying birds in your backyard and during your travels. Assist scientists tracking bird population changes by participating in bird counts and surveys such as Christmas Bird Counts, the North American Migration Count, and Breeding Bird Surveys. Find out about the Partners in Flight program in your home state. You can use your interest and knowledge of birds to help assure their future.
