Adaptable and opportunistic, the double-crested is the most abundant and widespread of the three cormorant species found in Oregon, occurring inland and on the coast.
Adults have deep, coppery feathers, bordered in black, that glisten with a green iridescent and offset a rich orange throat atop a long curved neck. The bird earns its name from plumes, ranging from white to black, that crown either side of the head during the breeding season.
The double-crested cormorant is a common breeder in spring and summer at bays and estuaries, and on islands and cliffs along the coast and lower Columbia River.
