Do you want someone to stick their neck out?
Red-throated pipit.
Heavily streaked breast, with the black forming solid lines, yellow base to lower mandible, and apparently streaked rump (the latter being the clincher).
Primary projection is a result of feather positioning I think, as only Pechora would show that feature normally, and that species has a dark loral smudge in front of the eye and an unstreaked rump. I also believe Pechora is virtually or completely unrecorded in Europe in spring, whereas Red-throated is regular.
The slight orange on the throat in the fourth picture is an indicator, but doesn't really help for me on the identification of this one.
Surprised it didn't call at all - hardly remember any Meadow or Red throated pipit I've ever seen that didn't, especially when taking flight.
