Hello,
I have been considering the background of the second, clearer photo, which shows some clear green grasses and reed. Therefore I doubt the actual photoquality to be overexposed.
Egyptian Nightjar is not so much the problem here, since the darker scapulars and darker leading edge, the row of connected pale tips to the lesser coverts, as well as the overall washed out grey, the headpattern and differing vermiculations all point to Eurasian.
The plumipes subspecies of Eurasian is quite much overall coloured as Egyptian, a sandy buffish rather than grey, keeping the paler row of coverts, rather than the scattered tips to the wingcoverts as in Egyptian. Considering the overall colour, it is more likely to be mistaken for Egyptian rather than correctly identified on that feature alone as an Eurasian. (Apart from the remaining plumage characters, which clearly show it as the last).
This bird then, being washed out, pale grey, shows hardly coarse, sharp markings to the wings and upperbody and the scapulars and lesser coverts, still holding more grey than in europaeus, lacking the sharper vermiculations as in europaeus or meridionalis(which has even sharper vermiculations).
Typical sarudnyi (if it excists) has more buff brown upperparts(only in the far east?), heavier streaking to the back. Since the last probably intergrades with the other subspecies, being intermediate with europaeus in the west and unwini in the south, the subject bird may hold its identity either with this southern thing, or with unwini.
That's how I reflected my own understanding, but would appreciate some deeper thing.
