Yes it is. Here's my story, if you didn't see it.
I had morning doves that nested in my window box at my old apartment. And one year one of the baby birds started flying before the other one. So I saw when the one left tried...he jumped an seemed to go straight down. I called animal control, they came out, he was ok, they picked him up in a towel and put him back up in the nest. And he was gone the next day so I guess he got the hang of it.
