Least Sandpipers are the smallest shorebirds in the world, weighing only an ounce and measuring 5 – 6 inches long. Their fall migration has already begun, with individuals leaving their breeding grounds in the subarctic tundra and far northern boreal forest for their wintering grounds in Central and South America. Banding has revealed that the eastern population of Least Sandpipers undertakes nonstop transoceanic migrations of about 1,800 to 2,500 miles from the Gulf of St. Lawrence and New England to northeastern South America. Not much bigger than a sparrow, this common but declining shorebird can be seen refueling on mud flats throughout New England during its fall migration.

Spotted Sandpipers are a relatively easy shorebird to identify, with their spotted breasts, their constant body-bobbing/teetering and the stiff beat of their wings. Although they are a shorebird, they can be found near freshwater ponds and streams throughout North America. Spotted Sandpipers differ from most birds in that the male and female roles are completely reversed when it comes to breeding – from courtship to parental care. The females establish and defend their territory, often arriving on nesting grounds before the males. Females court the males, performing display flights as well as strutting displays on the ground. Males, usually less aggressive and smaller in size, do the lion’s share of incubating the eggs and brooding the young chicks.
