Hawk Cam 2012: We Have a Baby Hawk! There is a new addition to the red-tailed hawks" nest overlooking Washington Square Park. At 11:02 p.m. on Monday, almost nine hours after Hawk Cam fans initially reported that one egg had a small hole, a white baby hawk emerged between two broken halves of an eggshell, making its debut on The New York Times's Hawk Cam. Members of the Hawk Cam chat room, including were elated with the news, and stunned that the birds didn't take the night off from hatching. John Blakeman, a raptor expert from Ohio who is a frequent participant in the chat room, said the hatching went as well as could be expected. Night hatches are not necessarily rare, he said, but they are rarely seen on camera. As for the other egg in the nest, he said that it could start pipping tomorrow afternoon. Red-tailed eggs are typically born about 36 hours apart. "This is going to be fun to watch," he said. The first speckled egg in the nest was spotted on March 6 by New York University's president, Dr. John Sexton, upon whose 12th-floor window ledge the hawks have built their nest, a two-foot wide tangle of branches. Since then, the mother hawk, Rosie, has been dutifully incubating her eggs from sunup through sundown, despite rain, sleet and feather-ruffling winds. The nest, lined with rope, shredded paper, feathers and other materials, will serve as the nursery for the baby hawk or hawks until they learn to fly on their own. Last year, Pip, the baby hawk named by readers, fledged after 49 days [June 23, 2011]. Rosie will feed her baby around the clock with bits of rat, squirrel, pigeon and other animals brought in by her mate, Bobby. Over a few weeks, the little one (s) will transform before your eyes from small fuzzy aliens with oversize Tweety-bird heads to juvenile hawks with awkwardly large yellow feet that seem to dwarf their stubby wings, then into something resembling the magnificent bird of prey they will become. The New York Times's Hawk Cam, which began broadcasting for a second season last month [on March 12], will continue to bring you live coverage of the red-tailed hawks Bobby, Rosie and the eyases, with additional analysis from our content partner, NYC Audubon. We'll be posting updates on City Room with developments on the nest, and on Twitter, follow @NYTMetro using the hashtag #nythawkcam.
