Congratulations are in order today for Rocky and Jubilee, the proud new parents of four baby peregrine falcons (or eyasses, as they're properly known) on the rooftop nest at 55 Water St.

The couple, who have been together for several years and made their home at 55 Water in 2008, previously had four children almost a year ago, named Brianne, Ramona, Matthew and Stephen. The new chicks have yet to be named, though the DEP will likely be on-site soon to tag the baby birds.

Falcons have been nesting at 55 Water St. since 1999, as one of 15 active nests across the five boroughs, and the building's website has been tracking their activity with a live BirdCam for several years. Though they're little more than precious fluff balls for now, soon, the eyasses will grow into fast-moving killing machines, diving for prey (like pigeons!) at speeds of 200 mph and using their talons to dislocate their victims's vertebrae. But seriously, who likes rats of the sky anyway? Apart from this guy.
