Hawk Cam: Looks Like an Egg Is Hatching April 9, 2012, 2:23 pm While we can't count hawks until they've hatched, it sure looks as if there is a hole in one of the eggs in the Hawk Cam nest high above Washington Square Park, the kind that is made by a baby hawk pecking its way to daylight. Folks on the chat room noticed it around 1:30 p.m. today - Day 34 after an egg was spotted in the nest and well into the expected hatch window. It can take a baby hawk, known as an eyas, as long as a half a day to break free from its shell. In a process known as "pipping," it will use a sharp horn-like attachment on its beak, known as an egg tooth, to slowly chip through to the other side. Feeling the vibrations underneath her, the mother hawk, Rosie, will begin to hover over the eggs rather than sit, standing often to push the eggs around the nest with her beak. Bobby and Rosie, stock up on diapers and pre-masticated rat. And hawk fans, stay tuned to City Room for updates. On Twitter, use the hashtag #nythawkcam and follow @NYTMetro.
