Conclusion on the dodgy duck!

I managed to get good views of the hybrid Tufty on Sunday and it seems to be a classic male Tufty x female Pochard. The vermiculation is indistinct, and appears plain grey and I even managed to notice purple gloss, (it says violet on page 379 of Collins) on the head. Never mind, but at least I was able to console myself with 3 more site year ticks in the form of 1 Yellowhammer, a Goldeneye and a fly over group of 4 Ravens.
