One Chick Left

Watching the Columbus Peregrine Falcon YouTube site this afternoon.
The youngest chick is still on the ledge, but I suspect it won't be for long.
It's running up and down the ledge flapping it's wings, hopping up and down. This behavior is building flight muscles and courage to leave the ledge.
I anticipate that it will leave the nest ledge tomorrow or the next day.

There was a large development gap between this bird and the "twins" (that's what I was calling the middle 2 birds because they were very close in size and abilities).

Below are pictures from last Thursday of the youngest bird and one of the twins. You can definitely see a big difference.

Here is a picture from today of the youngest practicing its balancing abilities on one of the lights.
