There were a couple of Caspian Terns at the pits today, an adult and an immature making it 144 species for the year there. I had a go with the camera at about 180m range, interesting blue wash overall, the sky was clear blue so presumably that is the reason. Here are a couple of shots, one without zoom on the scope eyepiece and one with about 50x, the image gets softer the higher the mag.
I checked out Bordelais Bog too, barely any bird activity but Slender Spreadwing was new for the site. Close examination of several small odes revealed Band winged, White-faced and Cherry Faced Meadowhawks. Also present the first Autumn Meadowhawk for the year…. Photo below.
