Over the weekend Nest 2 especially had a lot of rain. EB was often in this position.
Her chicks didn’t have much opportunity to develop their wing muscles and leg strength. Often flapping was to get rid of rain.
On Nest 1A the weather was a bit better and the young ospreys are much nearer fledging. This video shows the different stages of development between the nests.
The most advanced youngster is still Y1.
Today he helicoptered for several seconds on a few occasions. This was his best attempt.
