Another bitterly cold & murky day. Had a look at N. Killingholme Haven Pits for the 1st time in over a year but unfortunately 2 out of the 3 pits were frozen over. Around 25 Pochard & 15 Shoveler were the highlights on the ice-free pit. A Water Rail squealed & 15 Fieldfare were on the hedges. 9 Black-tailed Godwits were on the mudflats. Most surprising sighting of the day was a Marsh Harrier that flew east over the pits and continued over the river into Yorkshire -most likely a rare winter record for the pits.
Went on to Barton and had good views of the wintering drake Smew at Far Ings along with a Bittern in flight, Willow Tit, Bullfinch & a further 3 Water Rails heard.
Brief visit to Water's Edge but quiet and the only bird of note was a Green Woodpecker.
