Species associated with remnant prairie habitat were upland sandpiper
and grasshopper sparrow.
Breeding biology and habitat of upland sandpipers
on prairie chicken sanctuaries in Illinois.
We simulated three species: upland sandpiper (Bartramia longicauda), Henslow's sparrow (Ammodramus henslowii) and eastern meadowlark (Sturnella magna).
Using equal-effort sampling, the occurrence of Henslow's sparrow at high density was already 0.65 at the smallest field we modeled, whereas the occurrence of upland sandpiper at low density using equal-effort sampling was [less than]0.10 at the largest field we modeled.
We deemed analyses on species observed per [TABULAR DATA FOR TABLE 1 OMITTED] unit area surveyed as inappropriate as some species' presence on a given grassland tract was defined by a single breeding pair (e.g., northern harrier, upland sandpiper
During spring, summer and fall, the grasslands, woodlots and wetlands in these towns are also home to other rare visitors from afar, such as the upland sandpiper
, unusual sparrows and even the loggerhead shrike.

Chicago Botanic Garden yielded least bittern, upland sandpiper
and hoary redpoll.
We grouped territory densities of the four species that regularly sing flight-songs (upland sandpiper
, horned lark, bobolink, eastern meadowlark) and densities of the three species that are sedentary singers (vesper sparrow, grasshopper sparrow, savannah sparrow).
Letchworth's grasslands are important as historical nesting sites for northern harriers, upland sandpipers
and Henslow's sparrows.
The area's forests, grasslands, scrublands, and pine barrens will now be managed to protect the public water supply and habitat for wildlife such as whippoorwills, upland sandpipers
, and eastern box turtles.
And while it is important to short-eared owls, it also provides important habitat for almost a dozen other threatened and at-risk grassland-dependent birds, including northern harriers, upland sandpipers
, American kestrels, eastern meadowlarks and grasshopper sparrows.
Workers cleared acres of shrubland to reestablish open meadow for ground-nesting birds, including boblinks, meadowlarks, and threatened upland sandpipers
and Henslow's sparrows.
have some of the largest remaining populations of upland sandpipers
(Bartramia longicauda), grasshopper sparrows (Ammodramus savannarum), savannah sparrows (Passerculus sandwichensis), horned larks (Eremophila alpestris) and vesper sparrows (Pooecetes gramineus) (Crossman, 1989; Vickery et al., 1994).
Using binoculars and numerous bird guides, we sighted and identified upland sandpipers
as they touched down during their fall migration to wintering grounds in Argentina.
