The Gull Roost

It's getting dark, minus 2 and we're staring out across an old mine working that's frozen over.

Why?

Because today I saw, for the first time on my local patch, this year:
Great Northern Diver
Green-winged Teal (first time ever in the UK)
Yellow-legged Gull
Lesser Black-backed Gull
Knot

Today was a good day, a very good day!

BI is now 0.864, BBB = 15, and BCWP of +1
