A Ruddy Turnstone, perched on an outcropping of oysters, checks out what’s beneath him in the water as the morning tide ebbs last week near the mouth of Cedar Creek as it flows into Delaware Bay. Ruddy Turnstones usually forage on the shore, overturning rocks and stones and debris in search of food. On this morning, the Ruddy Turnstones amassed in large numbers crowding the rocks and, in this instance, an exposed oyster bed, waiting patiently as the Horseshoe Crabs laid eggs nearby in the rocks and the shallow tide waters.
