Several pairs of these Rock Pipits here at Epple Bay all year round.
No interactions present.
I don't think it is that easy to be sure from the picture that this is a Rock Pipit, as the legs are silhouetted and will appear dark against the watery background. It is well streaked on the back and the flank streaking can't be judged. Other angles would help to eliminate a Meadow Pipit.
