I think the pekinensis-option can be exluded by the absence of a clear-cut white throat and on the upperside there is no contrast between the inner and outer wing.

An additional image from the Lauwersoog-bird. The pale-tipped median underwing-coverts should confirm the ID as a Pallid. A hint of pale scaling on the undeparts can also be seen. A better picture from the finder FJ here; http://waarneming.nl/fotonew/1/5728801.jpg
