I'd spotted some distant small sea mammals breaking the surface to the south but could not ID them specifically.
My attention was drawn by our local Swallows alarm calling. I looked up and saw a Sparrowhawk.
It initially perched on the Heligoland trap. It then walked around the top of the trap peering in. Looking for it's next meal. It shows how adaptable these fantastic predators are. I captured a couple of images with my phone.
I have found a few corpses of passerines and also a Teal. I wonder how many avian predators are hiding around the island with Merlin and Peregrine spotted recently.
