This is the rarest of the Pribilofs breeding species of shorebirds. On a typical year there are between 4 and 6 pairs on the island. Semipalmated Plovers prefer open bare ground, or the flat areas in the sand dunes to breed. Often one can find a pair or two along the road on the east side of Big Lake, or around the salt lagoon. In late summer the family groups move to freshwater lakes (those which have experienced a fall in water level and are ringed with sand), or to the Salt Lagoon. Listen for their distinctivechew-weecalls, given in flight. For an explanation on the separation of this species and the accidental Common Ringed Plover, see the account of Common Ringed Plover.
