Here is another one of the four breeding species of shorebirds on St. Paul. If you see a bird flush from a roadside, it is usually either one of these or a Lapland Longspur. They are certainly among the most ubiquitous birds on the island, but the subspecies of Rock Sandpiper that nests here is an endemic breeder. The nominate C. p. ptilocnemis breeds only here but winters along the Gulf of Alaska. The mainland form C.p. tschuktschorum (say that five times fast!) passes through only as a migrant.
