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
Merge sort to insertion sort when fewer than seven array elements are being sorted. The Linux kernel uses merge sort for its linked lists. Python uses Timsort, another tuned hybrid of merge sort and insertion sort, that has become the standard sort algorithm in Java SE 7 (for arrays of non-primitive types), on the Android platform, and in GNU Octave. Merge sort In computer science, merge sort (also commonly spelled mergesort) is an efficient, general-purpose, comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the order of equal elements is the same in the input and output. Merge sort
