We went and spent Sunday evening with the good binocs in hand and all seemed very quiet. We thought for a moment that the chicks were gone. An adult suddenly turned up out on nowhere with fish in hand (talon) which stirred up the chicks. It looks like the chicks are feeding themselves now. They still stay down in the nest. I've never seen them close to fledging because I've never been out so much at this time of year, so I don't know what to expect. I'll just have to keep watching I guess.
