Breeding Bird Atlas 2 Species Accounts
- Very local and strongly declining
- Conservation action urgent
- Endangered Species
The genus Bartramia is monotypic, containing a single, unique species: the Upland Sandpiper. Upland Sandpipers are country birds, hunting insects by sight in fields of short grass. Although the bulk of their U.S. distribution falls in the prairies of the Upper Midwest, the ethereal piping of Upland Sandpipers has long been heard in the hayfields and meadows of Massachusetts. Today, these “grasspipers” are an endangered species in our Commonwealth and persist only at a few select locations.
Historic StatusThe “Upland Plover,” as it once was known, is something of a shorebird anomaly, a species that avoids the shore and breeds in large patches of open grassland. At one time, the farm-dominated Massachusetts landscape provided an ample amount of such habitat. Though thriving in the middle of the nineteenth century, Upland Sandpipers were no match for the market gunners who sought them for the reasons described by Forbush (1925): “Harmless and eminently useful, it nevertheless is one of the most luscious morsels to delight the epicurean palate.” Hunted nearly to extirpation, the remaining Upland Sandpipers in Massachusetts tried to seek refuge in the gradually dwindling grasslands of the state as they transitioned from agrarian to urban, suburban, and industrial usage throughout the twentieth century.
Atlas 1 DistributionLong after their former heyday in pastoral Massachusetts, Upland Sandpipers were already rare breeders in the Commonwealth by the time of Atlas 1. Their need for extensive open grasslands severely limited them, and only the largest active pasturages and airfields in the state were suitable for breeding. Accordingly, 40% of all blocks in the state supporting Upland Sandpipers were located in the Connecticut River Valley, where large areas of open farmland could still be found, and also where the large airfield at Westover Air Force Base was located. In the Coastal Plains, only 5 occupied blocks were scattered among coastal sites where suitable grassy meadows could still be found. A Probable inland block in the Bristol/Narragansett Lowlands was the only other breeding evidence found in Atlas 1.
Atlas 2 Distribution and ChangeThis shorebird, which was already rare and local by the time of Atlas 1, is becoming even more so now. Although the Upland Sandpiper is a listed species in the state, its numbers continue to decline, and the species is increasingly becoming restricted to managed airfields. The small remnant population still existing in the Commonwealth is following the same trend as the species’ continental population (McGowan & Corwin 2008). Without stabilization of the declining continental population, or at least stabilization on a regional scale, persistence of this species in Massachusetts appears to be tenuous at best.
