Do we know who the photographer was GCG? If you find it, I will added it to your post 
And it looks real to me ... often chicks will hang out together just like that ... and this photo reminds me of a really cute photo of Tupper peering around the edge of a building at me ...
I don't know where gemcitygemini got that photo from, TPC, but I would say that originally it came from the webcam earlier today.
The people at the site have a real interest in the birds, and when the fledglings are not in the nest, they will pan around the top of the library to try to find them.
I was watching the fledglings this morning too. Here are a few of my pics. The fledglings are on the wall which runs around the top of the library, which I believe is the highest building in Amherst.
Backed off a bit in the left pic; the edge of the nest box is visible on the right. In the pic on the right, part of the wall is visible, and the hills beyond.
Big Sister's first flight a few days ago was to the roof of the campus hotel. I have seen her fly, but have not yet seen Little Brother fly, although he was the first to "ledge", three or four days before his sister. He went for a walk along the top of the wall, and was gone for a while. When he came back, his sister yelled at him, and then reached over and gave him a kiss. These two are very close. For the last few nights, they have returned to the nest box to sleep in the closed-in part of the nest.
Big Sister is banded black/green 01/BE. Little Brother is banded black/green 76/BS. They have not been named, as far as I know.
