The mud flats at low tide, Boundary Bay, Ladner, BC. Offshore, thousands of Western Sandpipers and Dunlins wait for the receding tide to feed in the Biomass.

A Western Sandpiper walks through the shallows at low tide feeding on the nutrient rich Biofilm just offshore of Brunswick Point, in Ladner BC.

A mass of Western Sandpipers stops at Brunswick Point, Ladner BC to rest and feed, as they migrate from their Winter home in Mexico. In a few days they will leave again on their way to Alaska where they will breed, and raise their young. There were tens of thousands of them in the bay when I took this shot.
