Black Oystercatcher vs Surfbird

In short

The Black Oystercatcher is easily identified by its entirely black plumage and bright orange bill, while the Surfbird has a mottled gray and white appearance with a shorter, yellowish bill. Both species can be found along rocky shorelines, but their feeding habits and vocalizations also help distinguish them.
