The ocean battered the East Coast this past week, but for the Black Oystercatcher the seashore is a protective habitat. BirdNote’s Michael Stein reports.
CURWOOD: We've recently had a lesson in the sea's power, but as BirdNote®'s Michael Stein explains - for some birds, despite the ocean's occasional destruction, the seashore is a protective habitat.
[PIPING CALL OF THE BLACK OYSTERCATCHER, HEARD OVER WAVES ON ROCKY SHORELINE]
STEIN: We’re crouching on a rocky shoreline on the Pacific Coast – hearing the piping call of the Black Oystercatcher, a stocky black bird with bright red eyes and a stout, orange-red bill perfectly suited for jabbing limpets and mussels. Let’s listen again.

STEIN: A strong ebb tide is flowing, creating whirlpools and tugging at the kelp. On nearby rocks, harbor seals, looking like huge, taut sausages, have hauled out to rest. If we’re lucky today, we’ll hear some snorting!

STEIN: The oystercatcher is completely dependent on this marine shoreline for nesting and food, even in winter, when waves hit these rocks with awesome force. Yet what seems like an inhospitable environment to us must offer some advantages to the oystercatcher.
For one, wave-splashed mussels, the bird’s chief food, open more often, making them easier to attack and eat. For another, when the monogamous Black Oystercatcher nests on ledges just off shore, its eggs and young suffer far less predation by mammals. Now that’s something to celebrate!

SETIN: P.S. Contrary to their name, oystercatchers rarely eat oysters. I’m Michael Stein.
CURWOOD: There are pictures of Black Oystercatchers over at our web-site, loe dot org.
