Summer Shoreline, Part 1 - Turnstone Territory

The Ruddy turnstone is the most common, and the most colorful, sandpiper at Halibut Point during August.

Ruddy turnstone adult
Adults have been here since the beginning of the month, working their way south from their tundra breeding grounds. They depart from those upper latitudes before their chicks have matured, presumably to leave as much food as possible for the young ones who will have to start their first migration unescorted.

Ruddy turnstone, juvenile
Juveniles begin to show up at Halibut Point in late August or early September. Their bright orange legs identify them distinctively on the shoreline.


Turnstones are named for one of their feeding methods when searching for small mollusks and crustaceans at the tide line.


They become adroit foragers at the edge of the sea where morsels are churned up in the turbulence. They always keep at least one eye on those beneficent waves.
 


At the beginning of August turnstones share the shoreline with only a few other bird species.

Herring gull
Perhaps it's their quickness that allows them to get along amicably with omnivorous gulls.

Common eider
With ducks they're no more than a passing curiosity.

Turnstones bring an end to the ornithologically drab summer months on the shoreline. Feathered as they are, it's an extravagant turning point.

  1. Great photos & info! "American oystercatcher"?! What distinguishes that "Nationality"? This is the time to see the Egrets massing at Sunset on Ten Pound Island for their migrations. Keep up the beautiful work, Martin!
