A gull but no grebe

After a fairly birdless session out yesterday (windy...), most of today was spend doing scrub clearance on the disused railway at Alverton; a quick look at Kilvington Lakes beforehand didn't yield much, but as we finished, I noticed that a Black-necked Grebe had been seen there a short while previously. There was no sign of it when me and Graham G had a quick look, although it could've been hidden behind the spit. However, a pair of Goosander were present, as was a nice 1W Yellow-legged Gull, which then flew off west.
