Black oystercatchers, caught during their lunch hour,
are almost oblivious to the photographer's kayak.

Mussels are on the menu.

This oystercatcher will demonstrate how to open them:

First, find a good one and pull it off the rocks.

Then rotate it into the right position...

and poke your upper beak between the shells.

Cut the muscle that holds the shells together and flip it
around to your lower beak, spreading the shells apart.

Scoop out the good stuff on the inside...

and then look for more.
