Dunlin
Sorting Dunlin into subspecies is not easy but this one shows all the classic features of a British-breeding schinzii. It is short-billed, and has relatively pale rufous upperparts without a contrasting grey hindneck. The fact that it was on an upland reservoir right next to Dunlin breeding habitat is also another good pointer. There were two birds together and they were "singing" with that beautiful, pulsating trill that they make on the breeding grounds: xeno-canto.org/908418
