The Stilt Sandpiper (Calidris himantopus) or Micropalama himantopus, is a small shorebird; it bears some resemblance to the smaller calidrid sandpipers or "stints". DNA sequence information is incapable of determining whether it should be placed in Calidris or in the monotypic genus Micropalama. It appears most closely allied with the Curlew Sandpiper, which is another aberrant species only tentatively placed in Calidris and could conceivably separated with it in Erolia.
