Horned puffins have an unmistakable black and white plumage and a large, distinct, yellow and orange bill during the breeding season.
They are rare in Oregon, and most commonly encountered dead on the beach in winter or spring, or sighted more than 50 miles offshore in spring.
Individual birds, or possibly pairs, occasionally stay in Oregon for the breeding season and are seen attending colonies with Tufted puffins, but there are no records of breeding in Oregon.
