Arrived at low tide, and it was extremely low. I cannot remember so much exposed mud on the Thames for a number of years. No Viking longboats though. The River Lea at Bow Creek was in places, just a muddy trickle of water a few feet wide. Would these conditions lead to a change in the birdlife present. well not really. Gulls were more numerous, with a movement of Black- headeds up the Lea Valley, and it was crowded on the Dome mud. I counted 24 Great Black- Backs, which I think is a site record. Wildfowl and waders were usual in number for the time of year and a few birds were singing in the sunshine. A pair Of Reed Buntings chased each other in the north-east reedbed on the Dock, and a Black Redstart was at Virginia Quay. But on the whole it was quiet. An unwelcome sighting was the diggers on the old works at Orchard Wharf. They were clearing rubble and vegetation from the rear of the site. Lets hope the work is minor, and does not lead to a wholesale clearence of the site.
