I guess I won't be lynched if I print a post from the Yahoo group watching the peregrines. Here we go:

My office is in 101 California directly across from the nest vent in the PG & E building. Last year I watched from my window as the two
youngsters left the vent and took their first flight. I was terrified
as each chick, one at a time took that first step off the ledge. I was astounded as George and Gracie dived under the plummeting, albeit madly flapping chicks. From my vantage point, it looked as if the parents
were "lifting" the chicks up into the air to the top of the building!
Once on the top the chicks marched importantly back and forth on the top ledge. (Emphasis Janis.) It wasn't long before I spied the chicks flapping around and eventually finding their way back into the vent at least once.

Are all youngsters alike?
