The Semipalmated Sandpiper, Calidris pusilla, is a very small shorebird. Their breeding habitat is the southern tundra in Canada and Alaska near water. They are long distance migrants and winter in coastal South America with some going to the southern United States. They migrate in flocks which can number in the hundreds of thousands, particularly in favoured feeding locations such as the Bay of Fundy and Delaware Bay. This species is a rare but regular vagrant to western Europe.
