Field notes

  • Their laterally compressed bills are specifically adapted for either prying open or hammering through the shells of mollusks.
  • Juveniles require a long apprenticeship of up to 60 days to learn the complex physical techniques needed to shuck oysters and clams.
  • They are one of the few bird species that exclusively inhabits saltwater coastal environments, rarely venturing inland.
  • To defend territories, pairs perform 'piping ceremonies' involving rhythmic walking and synchronized, high-pitched vocalizations.
  • The species is easily identified by its piercing yellow eyes surrounded by a striking red orbital ring.
Habitat
Coastal beaches, salt marshes, sandbars, and intertidal oyster reefs.

Atlantic and Gulf Coasts of North America from Massachusetts south to the West Indies and South America.
