Every year in August, thousands of semipalmated sandpipers stop by the the Upper Bay of Fundy (home of the World’s highest tides), as they prepare for their 3-day non-stop flight to South America. As soon as the tide recedes and the mud flats start to be exposed, the shorebirds feed on mud shrimp. In a period of about 2-3 weeks, the sandpipers will double their weight, and get the energy they require in order to make their non-stop flight to South America. All images on this
