## Summary

The western sandpiper (Calidris mauri) is a small migratory shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific mauri commemorates Italian botanist Ernesto Mauri (1791–1836).
This is one of the most abundant shorebird species in North America, with a population in the millions.
Within the genus Calidris the western sandpiper is most closely related to the semipalmated sandpiper (Calidris pusilla).
