There have been two or three Sandwich Tern over-wintering in the harbour this winter, often seen fishing along the shorelines of Baiter, Arne and Sandbanks and are currently still in their winter plumage. However, today 4 summer plumaged birds arrived on the Brownsea Lagoon, found with the webcam. This is a pretty early arrival for migrant Sandwich Tern, so they could potentially be birds that have over-wintered a bit nearer than West Africa. Also in the harbour today seen from a School Birdboat was the Surf Scoter, 1 Common Scoter, 2 Great Northern Diver, 1 Black-throated Diver, 1 Razorbill, 1 Guillemot, 16 Spoonbill (15 Arne, 1 Brownsea), 1 Black-necked Grebe, 100+ Red-breasted Merganser and 20+ Great Crested Grebe whilst on the lagoon 100+ Bar-tailed and 300+ Black-tailed Godwit, 120+ Grey Plover, 300+ Dunlin, 8 Greenshank, 50+ Avocet and 100+ Oystercatcher. The Iceland Gull was reported again from Poole Park (4^th and 5^th) and the Black-necked Grebe, 3 Little Grebe, 1 Great Crested Grebe, female Goosander and 3 Goldeneye are all still present on the main boating lake. At Lytchett Bay 2 Spotted Redshank were on the pools field and in the bay 30 Brent Geese, 8 Red-breasted Merganser, 2 Greenshank and 3 Skylark were singing in the stubble field.
