Walking along in wales I heard a bird chirping loudly and when I looked it was doing a weird run fly run routine towards then away from me, thinking that it was trying to catch my attention ( which it did ) and distract me into following it I wondered if it had young nearby, carefully looking between rocks nearby I saw saw them, three birdlets in a line sheltering from the wind that had picked up over the last half an hour, I took some photo's quickly with a macro then without disturbing them or touching them ( as the mother could then abandon them ) I walked away and took some of the defensive mother with a longer lens, I'll upload her next.
Edit: the mother is here
