A mid-week jaunt in almost spring like weather, was in great contrast to the rain of near biblical ammounts, the prevoius day. Just the usual wildfowl were on the Basin, but I was alerted by a flash of electric blue, a Kingfisher, the first record this year. It landed very conveniently on a tree at the back of the reeds, where excellent views were had. There were many Finches present, Greenfinch and Goldfinch in song, 3 Linnets, and a few Chaffinch in the copse. A single adult Yellow-legged Gull roamed the mud in front of the Dome. The Thames was quiet, so had a stroll along Bow Creek, just one Redshank and about 50 Teal were present. On the way back to the Dock I encountered a male Black Redstart flitting among the buildings at Orchard Place, it was also calling. Back at the Dock the Tufted Duck had increased to 30. There was one very interesting sighting of an Isopod, a Sea Slater, only the second record here of this mainly marine invertebrate.
