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

Their appearance in flight is striking, with white patches on the back, wings and tail. The ruddy turnstone (or just turnstone in Europe), "Arenaria interpres", has a circumpolar distribution, and is a very long distance migrant, wintering on coasts as far south as South Africa and Australia.
