Hello marnix,
your pictures seems to show more than one bird. All show some barring on the tail, so they are Bar-tailed Godwits. No offense, sorry

The fourth picture shows the right short legs, that look to short for a wader of this size
 
no offense taken

i was under the impression that i observed just the one bird, however, i didn't keep it under observation at all times, and it's possible that a second bird entered the picture without me noticing - i had just assumed that the different colour pattern might be due to different light conditons
 
The one on pic #1 is a juv: plumage all of the same generation and with an internal pattern to the individual feathers that recalls that of Whimbrel.
 
As well as the barred tails that have been pointed out above which makes identification easy in this case, while obviously a diagnostic feature, this isn’t always visible in the field.

So, note the upturned bill (Black-tailed is straight) and in winter, the upperparts plumage of Black-tailed Godwit is a plainer grey, Bar-tailed upperparts give the impression of being patterned (with dark streaks through the feathers) with 1w showing uniform plumage (#1). In flight, the longer legs of Black-tailed clearly extend beyond tail, the wings of Black-tailed also show an obvious white bar with the white rump patch being squared off by a black patch on the lower back not present on Bar-tailed. When feeding on mudflats, Bar-tailed tend not to raise their heads as much as Black-tailed, feeding and foraging with head kept mostly down while walking.
 
thanks, i'll try and keep those pointers in mind next time i'm in the field (which might be some time since i'm in local lockdown in Cardiff, soon to be converted into a 'firebreak' lockdown)
