UPDATE: Two falcon eggs hatched in quick succession today. Tune in to see the little balls of white fluff.
Time to tune in to Falconcam.
The ledge atop the Rachel Carson building in downtown Harrisburg is busy with pre-baby arrival activity as the first egg of the 2012 peregrine falcon nesting season is set to hatch.
The falcons are nesting - as they have every year since 2004 - once again on the ledge of the building housing the state Department of Environmental Protection.
The Carson building is named - appropriately - for Pennsylvania's own groundbreaking scientist who a half-century ago warned the world of the dangers of DDT, the pesticide that nearly wiped out the peregrine falcon population.
Today thie Carson building can take credit for being the nursery for at least two dozen baby falcons who have gone on to find mates and nest on skyscrapers and bridges far beyond Harrisburg.
Back to the ledge at the moment, state falcon experts say that based on past incubation periods, we can expect the first egg of four eggs to hatch soon.
The female is exhibiting behavior that would suggest this as well. Some of the eggs have white spots on them, also an indication that the first hatchling will arrive very soon. The close camera views are provided to get the best coverage of this fascinating point in a Peregrine Falcon's reproductive cycle.

New York City's red-tail hawks beat the Pennsylvania falcons to the punch in the hatchling department.
The two chicks born to a mating pair of hawks nesting on a ledge on the New York University's Greenwich Village campus made their debut last week. Watch their progress - and yummy dining on rat entrails and pigeon innards - on hawkcom.
