The latest download from Nest 3 had some interesting footage, in particular an intrusion on 27 June when an unringed osprey followed the Nest 3 male to the nest as he returned with a catch. The intruder was around for about six minutes; some of the action including the intruder landing on the nest is in this video.
The adults are bringing in sticks and moss, building up the nest.
The male continues to spend time standing on the nest with the female and still feeds the chicks at times.
On Monday Chick 1 was just about able to walk a few tottery steps.
