Visit Hawk Mountain Sanctuary on “Bald Eagle Migration Day,” Saturday, Aug. 25, and see a live Bald Eagle up close and personal during a noon-time presentation by Carbon County Environmental Center. This free presentation will be held in the outdoor amphitheater, or indoors in the event of rain.

Bald Eagle Migration Day is designed to remind visitors that late August and early September is one of the best times to see bald eagles on migration. At this time of year visitors have a 40 percent chance of seeing a Bald Eagle at Hawk Mountain’s North Lookout, and a 52 percent chance between Sept. 1 and Sept. 15.

Also visiting that day will be John and Yoke DiGiorgio, authors of the newly released “Nesting Diaries: the Triumphant Journey of Four Bald Eagle Chicks.” Part photo-essay and part natural history, the book follows progress at an eagle nest along the Delaware River in Pennsylvania that successfully raised and fledged four young—an extremely rare phenomena. The DiGiorgios will be available to sign copies of their book, or just to talk and share video clips with visitors about their experiences. They will be found inside the Visitor Center from 10 am to 4 p.m.
