Members of the Bristol Bird Club are housed Friday and Saturday nights in the beautiful lodge of Natural Tunnel State Park where the club has an annual agreement with the state park system to present birdwalks. The state provides all accommodations to the club in exchange for its expertise with guided birdwalks. Members began to arrive in mid-afternoon, Friday, and enjoyed an evening of dinner and great social time. Saturday's walks will be to observe International Migratory Bird Day. Birders will gather in town squares, community centers,schools, parks, and refuges across the Western Hemisphere to learn more about wild birds, take action to conserve birds and their habitats, and simply have fun. Like any day of recognition, IMBD exists to focus attention on something important and marvelous -- in this case, the journey birds undertake between their summer and winter homes. IMBD was created specifically to highlight the migration of nearly 350 species of migratory birds between nesting habitats in North America and non-breeding grounds in South and Central America, Mexico, and the Caribbean. However, the day serves as an opportunity to celebrate all the species of birds whose annual movements enliven our lands, waters and skies. Natural Tunnel, called the Eighth Wonder of the World by William Jennings Bryan, has been attracting sightseers to the mountains of Southwest Virginia for more than 100 years. Today it is the focal point of Natural Tunnel State Park, a park which offers visitors not only spectacular sights but also swimming, camping, birding, nature activities, picnicking, hiking, a visitor center, an amphitheater and interpretive programs.
