“…Cheyenne Bottoms WMA has been designated as a hemispheric reserve by the Western Hemisphere Shorebird Reserve Network because of the large numbers of birds reported there (Senner and Howe 1984). Recent data reveal that there are substantial concentrations of shorebirds in other sites in the interior as weIl, notably in the Canadian Prairie provinces and the Prairie Potholes of the Dakotas (Table 10.1).…”

“…Until recently, the scientific literature on shorebirds has predominately described migration from the coastal perspective, which emphasizes large numbers of birds in one site with relatively long stays, during which the birds "refuel" in preparation for flight to the next site or their breeding or wintering areas (Myers 1983, Senner and Howe 1984, Morrlson and Myers 1989. As of 1984, of 58 major North American stopover or staging sites for shorebirds known, only 3 (5%) were in the Great Plains states, whereas 42 (72%) were in coastal habitats (Senner and Howe 1984).…”

“…For shorebirds and many other waterbirds, invertebrate food resources provided by a region are critical for overwinter survival (e.g., Senner and Howe, 1984) and can be an important indicator of landscape quality. Gaining knowledge of typical invertebrate resources available within wetlands is an important first step towards determining potential carrying capacity of a region for waterbirds and for assessing levels of enhancement and restoration needed to support target populations (e.g., Anderson and Smith, 1999;Augustin et al, 1999).…”

The value of agricultural wetlands as invertebrate resources for wintering shorebirds

Agricultural landscapes have received little recognition for the food resources they provide to wintering waterbirds. In the Willamette Valley of Oregon, modest yet significant populations of wintering shorebirds (Charadriiformes) regularly use hundreds of dispersed wetlands on agricultural lands. Benthic invertebrates are a critical resource for the survival of overwintering shorebirds, yet the abundance of invertebrate resources in agricultural wetlands such as these has not been quantified. To evaluate the importance of agricultural wetlands to a population of wintering shorebirds, the density, biomass, and general community composition of invertebrates available to birds were quantified at a sample of Willamette Valley sites during a wet (1999)(2000) and a dry winter (2000)(2001). Invertebrate densities ranged among wetlands from 173 to 1925 (mean AE S.E.: 936 AE 106) individuals/m 2 in the wet winter, and from 214 to 3484 (1028 AE 155) individuals/m 2 in the dry winter. Total invertebrate estimated biomass among wetlands ranged from 35 to 652 (mean AE S.E.: 364 AE 35) mg/m 2 in the wet winter, and from 85 to 1405 (437 AE 62) mg/m 2 in the dry winter. These estimates for food abundance were comparable to that observed in some other important freshwater wintering regions in North America. Published by Elsevier B.V.

“…The continued development of the United States coastline poses a serious threat to wildlife populations that occupy coastal habitats and estuarine wetlands in particular (e.g., Senner and Howe 1984, Daiber 1986, Andrews 1987, Whitman and Meredith 1987, Chabreck 1988, Bildstein et al 1991, Clark et al 1993. In Southeastern New England, birds comprising a diverse and dynamic avifauna rely on coastal wetlands throughout the year, a pattern of habitat use that conflicts sharply with the encroachment of human populations.…”

“…During winters in New England, large numbers of the American Black Duck (Arias rubripes Brewster) rely nearly exclusively on estuarine habitats for survival (Hartman 1963, Grandy 1972, Lewis and Garrison 1984. Additionally, many species of long-and short-distance migrant gulls, terns, shorebirds, and wading birds rely on coastal wetlands as resting and feeding sites, and the loss and degradation of these habitats may result in the displacement of such species from historically used coastal migratory stopover sites (e. g., Senner and Howe 1984, Myers et al 1987, Howe et al 1989, Pfister et al 1992. Thus, estuarine habitat loss at a regional scale may have broader, and even global, impacts on avian populations.…”

The habitat use of 126,566 birds observed in a 158-ha tidal pond/salt marsh complex in southeastern Massachusetts was recorded during 218 fixed-width transect and 241 remote-count censuses conducted year-round over 5 years (June 1985-May 1990. The most abundant bird groups overall were waterfowl, gulls, shorebirds, and songbirds. Overall avian abundance was greatest in the fall and winter. Avian richness ranged from a mean of 15 species in winter to 26 in summer; 131 species were sighted overall. Waterfowl, shorebirds, and gulls used tidal pond habitats (including flats) to a greater extent than marsh habitats; use of marsh habitats increased with tidal stage for each of those groups. Wading birds were more abundant in marsh habitats than in pond habitats, and songbirds used marsh habitats exclusively. The permanently flooded (subtidal) west portd segment was used to the greatest extent by cormorants and diving ducks and least by shorebirds and wading birds. Tidal stage influenced abundance patterns of shorebirds and gulls and activity patterns of shorebirds, gulls, and waterfowl. Time of day influenced abundance patterns of guUs. All macrohabitat types (intertidal and subtidal pond, emergent marsh) were used to a substantial degree by multiple bird groups indicating that the loss or disturbance of any type could negatively affect the estuarine avifauna.
