A gaggle of Norwich birders were listening outside their houses, pubs, universities last night, producing a fair assembly of nocturnal migrants (invismig). I think the tally included Wigeon, Teal, Mallard, possible Gadwall, Moorhen, Water Rail, Ringed Plover, Curlew, Green Sandpiper, Redshank, Oystercatcher, Common Snipe, Song Thrush, Redwing, Blackbird.
