The two chicks left the nest on the morning of 23 May, ie 3 days ago. The picture at the top is the last one of them in the box. You can almost hear them, "You go first", "No, after you", "No, after you". In that amazing away that nature has, after 23 days in a small wooden box, they flew out into a totally different world and survived. The middle photo is later that morning on their very first flight, the juvenile tufts are still just visible, and the bottom photo was today, three days later. So they have survived so far.
