Four species pairs that cause trouble on this coast, worked through at the distance you actually see them from.
Bar-tailed and black-tailed godwit share the estuary all winter and are separated at distance by posture and feeding rhythm long before you can see a wingbar. Black-tailed stands taller, feeds in deeper water and moves deliberately; bar-tailed hunches, works the tideline and stitches.
Both go drab. Golden plover keeps a warm buff wash and feeds in tight flocks on grass; grey plover is colder, works the mud singly with long pauses, and shows the black armpit whenever it lifts.
Bill pattern is the answer, but the shape of the yellow is what carries at range: a long wedge running to a point on whooper, a rounded patch on Bewick's. Neck posture helps — whooper holds it straighter and longer.
A ringtail is a female or a young bird and the two are genuinely hard. Look at the head pattern and the width of the white rump rather than the overall tone, which varies with light on the merse more than it does between birds.
Identification pieces in this journal carry the author's name and, where a record was later revised, a note saying so. We would rather print the correction than quietly drop the claim.
