4th Still Sitting Tight

As of this morning, the 4th nestling is still on the ledge and has not flown.  Nothing to be concerned with, in fact, it is better when they take their time and develop further before flying.  The remaining bird could be the last one hatched and/or it could be a female--females tend to fledge later than the males.
Reports are starting to come in of sightings of the fledglings around town.  Here is a photo of one of the falcons seen near the Riffe Tower on Sunday afternoon:

We appreciate the extra eyes out there!  More updates as information becomes available.
