North America's Largest Predatory Bird to Visit Hawk Mountain Nov. 10

Visitors to Hawk Mountain Sanctuary will have a 100 percent chance of seeing North America’s largest predatory bird on “Golden Eagle Saturday,” held November 10 with one-day-only eagle programs presented at 10 a.m., noon and 2 p.m.
This live raptor event is free of charge and coincides with the peak of golden eagle migration at Hawk Mountain. A trail fee applies to those who visit the scenic overlooks.
Courtesy of Shaver’s Creek Environmental Center, visitors will see a live, non-releasable golden eagle in the Sanctuary’s Outdoor Amphitheater (indoors in event or rain). Each program also will include one owl and one hawk species to show adaptations among species, and to illustrate what sets the golden eagle apart from other raptors.
The golden eagle is a true rarity throughout the northeast and an average 90 pass Hawk Mountain each autumn, the bulk during the first two weeks of November. The bird sails by on plank-like wings that stretch more than seven feet and typically migrates alone, heading south on updrafts and thermals along the Kittatinny Ridge or “Blue Mountain.” However, northwest winds bring the most golden eagles, such as the 48 that passed Sunday, November 4 on the winds following Hurricane Sandy.
Early November also is the best time to see both bald and golden eagles in the air on the same day, and visitors also can expect to see large numbers of red-tailed hawks, the Sanctuary’s third most numerous migrant. Red-shouldered hawks along with black and turkey vultures begin a steady exodus past Hawk Mountain, and days following a cold front are best for seeing all species.  
Other migrants include northern finches, along with purple finches and pine siskins, and loose flocks of common loons. Rarer birds include red crossbills and evening grosbeaks, both of which have been sighted every few days.
Hawk Mountain Sanctuary is a prime observation point for autumn raptor migration because of its location along the easternmost edge of the Appalachian Mountains. Hawks that pass here use ridge currents for uplift like glider pilots on long-distance flights. In addition to birds of prey, hummingbirds, monarch butterflies, songbirds and waterfowl use the Appalachian Mountain Flyway.
Some species follow the Appalachians to their end, before heading south to the coastal plains of eastern Mexico and falling out to the tropical forests of Central and South America. Biologists believe that the golden eagles that pass are moving south from nesting grounds in Quebec and the chilly, northern provinces of Canada. There are no documented golden eagle nests in the state of Pennsylvania.
The official Hawk Mountain raptor watch runs from August 15 to December 15. As the world’s first refuge for birds of prey, the Sanctuary boasts the longest-running database of hawk migration in the world.
Visitors should wear sturdy shoes, dress in warm, layered clothing, and bring binoculars, something soft to sit upon, and a daypack. The Sanctuary has no trash receptacles on site and follows a carry in–carry out trash policy. Snack food and water are available for sale in the Visitor Center.
Trails to the lookouts are open daily from dawn to dusk. Weekday trail fees are $6 for adults, $5 for seniors and $3 for children 6-12. Weekend trail fees through November 30 cost $8 for adults and seniors, and $3 for children 6-12. Trail fees include a variety of free weekend programs, which continue through November 18.
Hawk Mountain Sanctuary is a non-profit, member-support organization located just seven miles north of I-78 near Hamburg (exit 29B). Memberships, starting at $40 for a family, provide free admission daily for up to one year. Trail fees and membership dues support the Sanctuary and its conservation programs.
