Adult

In the first picture, you can see a large amount of wear on the tips of the tertials and flight feathers. That amount of wear is a sign of an adult. Adults have had those feathers since they last moulted, at some time over the late autumn/winter. They have migrated north and then nested with them and so they have become heavily worn. A juvenile, at this time of year, would have perfect flight feathers with no wear at all.

Many thanks for comment...

Many thanks for comment, that's really interesting. It was very noticeable when looking with my binoculars and I was trying to think of the reason for these feathers. I've just added another image showing these feathers in more detail.
