I was on the lookout for a rumored Wandering Tattler along the west side of the park when I saw this bird in plain view atop a barnacle-studded rock near the blue steel sculpture. Not a Tattler. Definitely a Black Turnstone (Arenaria melanocephala). Oddly, all by itself. Well, almost. I did catch a glimpse of a second one. But there wasn’t the usual little mob of them, such as I saw recently relaxing on the east side of the park (“Stones.” Oct 4 2022). After a bit of preening in the sunshine, this bird set about foraging. It had an ample meal spread out at its feet. The low tide bared slopes of barnacles. With a beak as hard and sharp as a woodpecker’s, the bird punctured the calcium ceiling inside the barnacle’s little fortress and easily extracted its living occupant. Turnstones are energetic, hard working, and versatile. This bird knows the rhythm of the waves. It’s unafraid. It doesn’t mind getting wet. It makes its home at the water’s moving margin.
