Excellent shots of them Alison.  I wish them luck! 

Alison:
Thank you for the reply, TPC. I do realize how high the mortality rate is during the first year. As far as I know there is not a fledge watch here - since the nest is at a power plant, I'm not sure they would want people running around on their property, for security reasons. Some of the plant employees do try to keep an eye on the birds and will search on the grounds if need be.

The other two chicks are on the move.

The Peregrine Chick:
Unfortunately Alison, that's why there is such a very high mortality rate among hatch-year birds.  Nestboxes and webcams and volunteers can only provide so much support, ultimately, its up to the fledgling itself.  It is also possible that the chick had an underlying problem and that is what caused the chick to fledge earlier and/or run into difficulties during fledging.

They are three females, which is why I am concerned about the first to fledge. Also, one of the cam operators at King is really good about moving the cam around to check on other possible perches or problem areas, and there has been no sign of her. Both parents have been bringing food for the other two frequently, and perching where they can watch over them.
