I visited the St. John nest and saw a relaxed fledgling in the early afternoon. I missed all of the action that took place later in the evening. Late in the evening, the eyass fledged and went over to the St. Luke Hospital roof. (I missed all of the action that took place in the evening. I never thought an eyass would fledge at 7:43 p.m.!, so I went to Astoria!)
