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
Ruddy turnstone coasts. In Africa, it is common all the way down to South Africa with good numbers on many offshore islands. In Asia, it is widespread in the south with birds wintering as far north as southern China and Japan (mainly in the Ryukyu Islands). It occurs south to Tasmania and New Zealand and is present on many Pacific islands. Some non-breeding birds remain year round in many parts of the wintering range, with some of those birds still taking on breeding plumage in the spring and summer. The ruddy turnstone has a varied diet including carrion, eggs and plant material
