It was quite content feeding in the soft mud at the waters edge, 20 metres upstream from the footbridge quite unconcerned by passing walkers, even spending some time preening and roosting.
This individual has a long bill tapering to a downcurved tip and dark legs, white beneath and in the overcast/foggy conditions appeared grey brown but with small areas of browner tones visible around the crown and neck. The bird was not heard to call and I didn't see it arrive or depart so did not see it in flight. I believe alpina race birds have the longer bill length but there is much overlap. Amazing to think that in a few weeks this bird could have travelled NW up along the shorelines of Scandinavia, Northern Europe or even as far as Siberia.
