The Three Graces Tidal Area (Birding Oregon p. 127) lies along the shore of Tillamook Bay, just south of the town of Barview. It is a small site, but the offshore rocks and rocky shoreline attract a nice variety of birds.
The best times to bird this site are in between high and low tides. When the tide is up, the small rocks are submerged. When the tide is too low, people sometimes walk out to the rocks, thus scaring the birds. Brown Pelicans, Common Loons, Harlequin Ducks, and other waterfowl are often seen swimming in the area. In winter, Rock Sandpipers and Surfbirds feed on the exposed rocks and shoreline.
Peer over the edge of the path to scan the shoreline for rockpipers and gulls. A scope is useful for checking the more distant offshore rocks.
A closer view of that distant rock. Pelagic, Brandt’s, and Double-crested Cormorants can all be found here, sometimes allowing side-by-side comparison. This photo shows mostly Pelagic Cormorants, with a possible young Double-crested on the right.
