Diademed sandpiper-plover is poorly known and uncommon, and rarely recorded. While its habitat is thought to be secure, it is possible that overgrazing is a threat. Diademed sandpiper-plover The diademed sandpiper-plover or diademed plover ("Phegornis mitchellii") is a species of bird in the plover family Charadriidae. It is monotypic within the genus Phegornis.

The species is found in the Puna grassland ecozone of the Andes Mountains from Argentina and Chile, through Bolivia to Peru. In this habitat it prefers mossy
