The top bird is a Black Turnstone photographed in Pacific Grove, California. You must travel to the west coast to see this bird because it breeds in northern Alaska and winters along the Pacific Coast from Alaska to California. The only plumage change during breeding season is a white eye stripe and a patch of white between the eye and the bill. The Ruddy Turnstone, shown in the bottom two photos, also breeds in northern Alaska. But its breeding range also includes the far northern areas of the Arctic Tundra. It winters along both the east and west coasts of the United States. Ruddy Turnstones have a dramatic plumage change for breeding season. The photo on the left, taken on Sanibel Island in Florida, shows the winter plumage. The photo on the right, taken in Duluth, Minnesota, shows breeding plumage. It’s so different that you might think these are separate species.
