Ruddy turnstone threats during migration and winter. They estimate that the Canadian population is 100,000–500,000 adults. The Canadian Wildlife Service estimates that the worldwide population of ruddy turnstones is 449,000, and that 235,000 are breeding in North America while the rest are breeding throughout the Arctic regions. They are very common and widespread. Their remote breeding range and widespread winter range should help them remain a common species. Ruddy turnstone The ruddy turnstone ("Arenaria interpres") is a small wading bird, one of two species of turnstone in the genus "Arenaria". The scientific name is from Latin. The genus name "arenaria" derives from

Birds of the subspecies "morinella" are smaller with darker upperparts and less streaking on the crown. The ruddy turnstone has a staccato, rattling call and also a chattering alarm-call which is mainly given during the breeding season. The ruddy turnstone breeds in northern latitudes, usually no more than a few kilometres from the sea. The subspecies "A. i. morinella" occurs in northern Alaska and in Arctic Canada as far east as
