See what it took to bring live streaming video of a pair of Red-tailed Hawks on Cornell’s campus. The technical crew worked day and night to install the cams early in the nesting season, before the hawks laid their eggs on a light tower 70 feet above an athletic field. To see the live feed during the nesting season, go to www.allaboutbirds.org/cornellhawks.

Under the cover of the predawn darkness, viewers of the Cornell Hawks‘ cam were the first welcome a new nestling hawk to the world. Big Red was incubating at the time, and while sightings of the nestling were difficult, she could be seen pulling pieces of broken eggshell from beneath her. As morning’s light arrived, we got our first glimpse of the hatchling, looking downy and bobbling energetically beneath its parents (watch highlight.)
