Based on Tony's photos I identified it as Marbled Duck x Yellow-billed Teal hybrid, but after seeing Murray's photos I started to wonder if it was in fact Marbled Duck x Yellow-billed Pintail. On Sunday I went to see the bird in the flesh and this reinforced my belief that it involved Yellow-billed Pintail. After some further discussion with the likes of Joern Lehmhus, perhaps the world's foremost expert on hybrid ducks, I now think I was right the first time, that it was Marbled Duck x Yellow-billed Teal. I won't go into detail here as I've already done so elsewhere, but here is the bird.
probable Yellow-billed (Speckled) Teal x Marbled Duck hybrid, Rollesby Broad, 24th January
I couldn't find much else here, or across the road at Ormesby Broad

Coots, Rollesby Broad, 24th January
I headed round to the Filby side where I failed to find anything of interest at Ormesby Little Broad - just a couple of Water Rails and a Treecreeper heard calling. Across the road at Filby Broad I couldn't find the Mandarin that had been seen a few minutes earlier, just a couple of Goldeneye.
Stopped to check a Pink-footed Goose flock near Clippesby on the way home. Couldn't pick out anything other than a leucistic Pink-foot.
Not much to report from my lunch breaks last week - a flock of c. 180 Fieldfare at Houghton, a Grey Wagtail over Flitcham and 3 Sparrowhawks. Also a Barn Owl on the way to work at Tattersett.
