The Nest Outside Our Window

This nest is in the hedge that's against the building where I work. It had four robin chicks in it, but they were getting very big, and yesterday two of them disappeared. They had feathers, and though they looked a little ragged (some pin feathers still showing) I'm hoping they flew away, and are alright now. The two remaining chicks you can just see if you enlarge the photo - they may be gone tomorrow...

UPDATE
The last two chicks disappeared friday afternoon... hopefully they flew away...
