 Snipe sp. at Lower Moors
Yet another very challenging Wader seen this Autumn although without the excuse of viewing range on this occasion! Seeing a Wilson's Snipe on this very pool on Lower Moors with JFC & ADW back in 1998 and with the only other species of Wader seen at Lower Moors today being Solitary Sandpiper, Lesser Yellowlegs and Pectoral Sandpiper this individual was clearly worthy of close scrutiny! Unhelpfully and annoyingly, in the hour or so I watched it, it only raised its wings briefly the once when all I could see was that the axillaries and underwings appeared 'dark grey'. Hence, unfortunately no critical detail was seen re its axillaries or trailing edge. Likewise, unfortunately it raised its wings whilst I was watching it rather than pointing the camera at it. Furthermore, it was not alongside any other Snipe for direct comparison. Looking at what can be seen in the above images and comparing the features with Nils Van Duivendijk's Advanced Bird ID Guide, pro-Wilson's Snipe features would include the dark centres to its mantle feathers (although the extent of the brown patterning to the lower scapulars is of concern being clearly more than shown by the Ouessant bird (Birding World 18: 11)); its head being a warmer brown, and particularly when seen in poor light, contrasting with the rest of its plumage; its virtually solidly black lateral crown stripes (albeit a few brown 'nicks'); well-defined and broad barring on its breast-sides and flanks (dark and pale bars almost of equal width) sharply demarcated against a white background; generally being 'colder' coloured (albeit enhanced in the poorer light when the top 5 images were obtained - note it looks brighter and more colourful in the lower 3 images) with the brown on the underparts restricted to its breast; the tertial patterning fading away slightly towards the base; and its supercilium 'bulging' before its eye. In addition, to me at least, the patterning of its wing-coverts appear a close match to that of the 1998 bird. However, as Common Snipe is such a variable species, without anything like the full suite of characters of Wilson's Snipe being seen, elimination of Common Snipe would seem impossible.
