Garganey duo & Dusky again

A pleasant but cold walk down to the Carlton Marshes Scrape, I saw Chris M who'd just seen the Garganey. Looking from the Mound, I initially could seen no sign, I was joined by Neville L and he couldn't see them either. We saw a pair of Gadwall and male Teal plus a Little Egret. It wasn't until Robert H walked up he spotted them on a grassy spit, they just walked into view, the fine male and female Garganey. They spent most of their time walking in out of view on the grassy spit and later on they had walked around 100 yards over to the right. We then went to Fisher Row and at the spot we met Andrew E, Robs Wil & Win, James W, Paul & Jane and others. The bird had been seen again. I saw a movement and low on the left of the bush, the excellent Dusky Warbler was seen sitting on a branch and showed well for me for a good minute and a half (perhaps payback for the time spent over the previous few days?) before it moved back. Viewing the east side of these line of bushes from the tea garden path, I first saw a Treecreeper scaling one of the trunks of these bushes and then a Chiff- Chaff moving through the bushes prompted the Dusky Warbler to chase it off and then it moved right through the bushes between a dead tree and a broken tea stump.
