Small/medium brown bird, with streaks on upper chest, pale eye stripe. Undulating flight.
No interactions present.
Not a Woodlark, as that would have a clear buffish-white stripe above the eye, going right to the back of the head.
This is a Meadow Pipit or a Tree Pipit, but I am tired tonight, so will let others argue over it!
My Flickr photos...
We agree with it being a Pipit - Meadow or Tree - but most probably the Meadow.
