About the American Oystercatcher#
The American oystercatcher (Haematopus palliatus), occasionally called the American pied oystercatcher, is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby observed the bird eating oysters. The current population of American oystercatchers is estimated to be 43,000.

Field-craft tips#
- Rocky shores at low tide.
- Bright sand and surf fool meters — dial in exposure manually or with auto-ISO and compensation.
- Sightings peak in April, May, June and July, which is when you'll have the most chances.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
