嗯，有個名稱叫 flegde，指的是幼鳥成長到羽翼豐滿肌肉強健能夠開始練習飛行的階段。
Osprey 魚鷹是由爸爸來教導幼鷹覓食捕魚，三隻小鷹其實從離巢開始就已經在練習捕魚，
但是仍會回巢跟爸爸要魚吃，這個時期大月會持續 2-8周，參見下面的觀察紀錄
" After fledging, young ospreys begin to hunt on their own.
However, they often continue to return to the nest to receive food from their parents for two to eight weeks after fledging.
Because ospreys migrate individually, juvenile ospreys must be fully independent of their parents by the time the southward migration begins."
(Poole, 1989; Poole, 1994)
媽媽 Piret 的確已經先行離開，開始南飛過冬的年度旅程，飛行的路線可以在 Migration map (
