Hooting and a hollering

I headed out for a walk late morning to one of my usual spots. Just 2 minutes into my walk i had my blip! This oystercatcher was going mental, hooting and a hollering round me. It was obviously guarding chicks. 
I could have had my pick today, with damselflies and marsh harrier shots to choose from but have stuck to my original plan and blipped the oystercatcher. Other shots can of course be seen here
