About the Least Sandpiper

The least sandpiper (Calidris minutilla) is the smallest shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific minutilla is Medieval Latin for "very small".

Within the genus Calidris, the least sandpiper is most closely related to the white-rumped sandpiper (Calidris fuscicollis). This species has yellow-green legs and a short, thin, dark bill. Breeding adults are brown with dark brown streaks on top and white underneath. They have a light line above the eye and a dark crown. In winter, Least sandpipers are grey above. The juveniles are brightly patterned above with rufous colour and white mantle stripes.

This bird can be difficult to distinguish from other similar tiny shorebirds; these are known collectively as "peeps" or "stints". In particular, least sandpiper is very similar to its Asian counterpart, long-toed stint. It differs from that species in its more compact, shorter-necked appearance, shorter toes, somewhat duller colour, and stronger wingbar.
