Sker Plover

The Golden Plover at Sker is causing a few of us some headaches. Whether it is an American or an European, people can judge for themselves. However, my initial feeling is that this bird appears to have too much of an European influence to be treated as an American, not a pure one at any rate! Hopefully I'm wrong.
Discussion on this bird may run but I'll post a few pics here to help things on their way. The axillaries, and underwing generally, are very much as one might expect for a European Golden Plover (EGP). Also pro EGP is the shortish wing projection. Conversely, pro American Golden Plover (AGP) is the primary projection, which appears at least 80% with 5 visible pps. The bill appears small and the bird appears leggy even in the short grass. The face has rather an open look to it which may explain why the supercillium doesn't jump out at you, or maybe it should be bolder.
This bird is seemingly a first summer bird with much of the juvenile plumage worn and faded. This might explain the rather cold tones in appearance.  If this is an AGP then it is an unusual looking one, but whatever the case no-one can deny it is a challenging and interesting bird.
