Solitary Sandpipers (although not truly “solitary” birds, they do migrate in smaller flocks than most shorebirds, sometimes even alone) are passing through New England as they migrate to the boreal forests of far northern Canada and Alaska, just south of the tundra, to nest. One of the more fascinating oddities about this bird is that it is one of only two sandpipers (out of 85 species worldwide) that nests in trees in the abandoned nests of songbirds, and not on the ground.

Solitary Sandpipers (Tringa solitaria) nest in the boreal forests of Canada and Alaska (in the abandoned tree nests of several different song birds!), and winter in the tropics, from northern Mexico south through much of South America. Individuals started their nocturnal migration south in June, which is both inland as well as offshore. In the fall, some birds appear to fly southeast over New England towards the Atlantic Ocean, as if on direct course to South America, while others follow the eastern coastline. Although their migration over New England peaked in July, you can find them through mid-October on the shores of ponds, resting and feeding during their long flight. As their common and species names indicate, they migrate singly, not in flocks like most migrant sandpipers.
