I had a walk around around Brooklands, Abbey Mead and along the river this morning. It was drizzling and cold with a bitter north wind and there wasn't really much to see to be honest. I'm ninety five per cent certain I saw a green sandpiper though, medium length bill, dark underwings and very pale/white undercarriage, it flew down river quite fast calling a couple of times but i'm not absolutely sure so no tick on that one. Also nice to see the large flock of goldfinch still around the NW corner of Brookland lake. I stopped on the piece of high ground to the west of the sunken marsh and as I looked over towards the heronry further upriver something must have spooked the herons because they all suddenly took to the air, I counted twenty three flying just above the trees, with more still visible in the branches, it was quite a sight to see so many in the air so close together. They circled around Abbey Mead for a few minutes before returning back to the trees. Later on while walking back down the river path there were sixteen all standing together on the exposed mudbank by the creek, I think the collective noun might be a siege of herons which did seem to suit the scene on this occasion. I tried to get close to take a picture but with sixteen sharp pairs of eyes I didn't stand a chance. When I got home I looked out of the patio doors and could see this heron (below) fishing in it's usual spot on the far bank of the lake and wondered if it was one of the twenty three I'd seen earlier. I wouldn't be at all surprised.
