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
Insertion sort elements of the unsorted input, while in insertion sort they are simply the first "k" elements of the input. The primary advantage of insertion sort over selection sort is that selection sort must always scan all remaining elements to find the absolute smallest element in the unsorted portion of the list, while insertion sort requires only a single comparison when the "k"+1th element is greater than the "k"th element; when this is frequently true (such as if the input array is already sorted or partially sorted), insertion sort is distinctly more efficient compared to selection sort. On average (assuming the
