The hawks have been nesting on a third-floor windowsill overlooking Logan Square since 2009. And not long after they arrived The Franklin Institute set up a webcam to watch the pair nest and their offspring hatch.
The excitement begins in March - three eggs are already in the nest this year - and continues through June when fledglings leave the nest. Stay tuned for an April hatching.
This spring is the fourth year running that Philadelphians can watch the cycle online
. There's also a blog
for truly avid hawkwatchers to follow along in extreme detail.
For background on the hawks, the Franklin Institute made this video.
