There's a poem in my current collection, The Elephant Tests, called At Frampton Marsh, written some time after a visit to the RSPB reserve just outside Boston, Lincolnshire, a few years back.
I was there again on Friday, being shown around by warden Toby Collett, and was amazed at just how much it has developed even in the last couple of years. A bird list of 70-odd species included Glossy Ibis, two Pectoral Sandpipers, around 10 Little Stints, 50-plus Curlew Sandpipers, 10 Spotted Redshanks, hundreds of Black-tailed Godwits, Merlin and Marsh Harrier. The particularly high numbers of waders (I've never seen that many Little Stints or Curlew Sands together) were in part due to a very high tide which came right up to the sea wall.
Here's a little group of five Curlew Sandpipers, and a larger gathering of (mainly) godwits, although there were Dunlin and Knot among them.
