Hawk Cam 2012: It's Fledge Day! The adolescent hawk stars of the live reality raptor series broadcast live from New York University's Bobst Library, named Boo and Scout, fledged on Monday night after nearly 50 days of life. Just before 8:30 p.m., as the light was fading on Washington Square Park, one of the eyases took flight from the 12th-floor nest at the library. It sailed to an eighth-floor window ledge at N.Y.U."s Silver Center, located on the east side of the park. Then, about 10 minutes later, the second hawk took flight and joined its sibling on the same ledge. D. Bruce Yolton, who writes the Urban Hawks Blog and who witnessed the event, said on the Livestream chat accompanying the Hawk Cam that "double fledges like this are unheard of." The moment was chronicled by the blogger Roger_paw, who noted that darkness had prevented hawk watchers on the ground from seeing events clearly. The pair will most likely spend the overnight hours on the ledge before making other attempts at flying. At midnight on the Hawk Cam, only Rosie, the mother hawk, could been seen standing sentinel in the nest at Bobst Library. The baby hawks are not likely to return.
