Hello,
I must admit first gut feeling is: this surely has to be a Barn Swallow? Please note:
- appearant whitish underwing-coverts
- the right head pattern with an paler supercilium, divided from the pale throat by a dark eye-stripe
- with much wishful thinking I can just make out a darkish breast band???
- appearant darkish/coloured undertail-coverts?
- can I see the right reddish hues in the right areas for a Barn Swallow???
No offence you know: but judging these points with confidence is extremly difficult here, as you are surely aware of.
Do you have more pictures?
Anyway: its no Pratincole because your bird lacks the white rump, which should be evident here
