May I ask how to assure this snipe is either common or pintail? The most diagnostic feature to distinguish them is the tail feathers and the underwing pattern but both could not be shown.
Appreciated if any experienced birders can advise.

Many thanks for the detailed information on the different scapular pattern of Swintail and Common snipes.  Now I have more confidence on distinguish them even they don't move a lot in wild fields!
