Few seabirds have been labeled "stunning;" but with their graceful flight, boldly patterned upperparts, and brilliant white underparts, these birds truly are one of the most beautiful in Oregon waters. They have a black cap, wings angled forward, long body and tail, and a unique dark 'M' pattern against light gray back and wings.

Often seen in small groups mixed among other more abundant shearwaters, they sometimes form pure flocks all flying in gracefully synchronized flight.

While regular in Oregon in late fall, they are still uncommon enough to excite observers when encountered at sea.
