Mystery sandpiper from San Cristóbal, Galapagos (3 Viewers)

[SteveClark]

Two small sandpipers feeding with a much larger Ruddy Turnstone on 4th April 2024. I'm thinking Western Sandpiper based on length and shape of bill but other possibilities seem to be Semipalmated and Least Sandpipers. Your suggestions will be much appreciated. Heavily cropped photos attached.

Cheers
Steve

First has yellow legs and so must be least. Second is probably the same but Western if not based on bill
