About This Species

This all-black shorebird is a fixture of rocky shorelines along the Pacific coast of North America, where it uses its long orange-red bill to pry mussels and limpets from exposed rocks at low tide. Its loud, piercing calls often announce its presence before it comes into view against dark, wave-washed rocks. Low tide periods, when rocky intertidal zones are exposed, offer the most reliable viewing as birds actively forage.

Ethical Viewing Guidelines

  • Keep a distance of at least several meters when birds are feeding or resting, and be especially cautious near rocky ledges where nests can be difficult to spot among the substrate.
  • Migratory bird protections apply in both the United States and Canada across this species' range, making it illegal to disturb active nests.
  • Avoiding travel across exposed rocky habitat during the spring and summer breeding season reduces the risk of accidentally flushing a nesting pair.
