So we left the beach and had a look on the lagoon. There was loads of different ducks such as: Teal (40+), Mallard (40+), Wigeon (5) and one rare duck... a gadwall. We looked away from the lagoon and had a look across a field where we had seen a kestrel flying overhead and hovering so we went and look. No sign of it today. But, we looked across the field and noticed a bird of prey which at first had us baffled. It was about the size and shape of a red kite but without the forked-tail. I took a picture as it came closer and when we got home and had a look on the RSPB website we found out we had been watching a female Hen Harrier!
