When I first saw them, they were feeding on the white berries on a row of sorbus trees in the part of Bessemer Court nearest to John Lewis depot. Later they were resting and preening in a nearby tree. This is close to where I saw some last week, so they must be staying around here for a while. There were at least 19 birds today.
A quick look at Willen later found amongst the usual ducks, 3 male goosander and 2 goldeneye (Tony Garner)
