Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
The Prairie Naturalist
I examined patterns of bison (Bison bison L.) hair use by passerine birds nesting in the Tallgrass Prairie Preserve, Osage County, Oklahoma, 2002-2004. I collected and dissected 103 nests of 15 species into their constituent components. Nests were predominately composed of herbaceous material such as grass stems and leaves. Woody material and mud were rarely used. Bison hair was the most prominent zoological material used in nests, with lesser amounts and occurrence of arthropod silk, snake skin, feathers, jack rabbit (Lepus californicus Oray) fur, and man-made materials such as cellophane and string. At least one nest of 13 …
Long Distance Molt Migration By A Giant Canada Goose From Eastern South Dakota, Bobby J. Anderson, Charles D. Dieter
Long Distance Molt Migration By A Giant Canada Goose From Eastern South Dakota, Bobby J. Anderson, Charles D. Dieter
The Prairie Naturalist
To reduce crop damage by resident giant Canada geese (Schaible et al. 2005), the South Dakota Department of Game, Fish and Parks (SDGFP) initiated a program to reduce goose nesting success in eastern South Dakota. One management tool used by SDGFP personnel was the destruction of giant Canada goose nests. When a giant Canada goose has its nest destroyed, they are known to initiate a molt migration (Mykut 2002, Luukkonen et aI. 2008). We attached Platform Transmitting Terminals (PTT; model ST -19) to document and describe molt migrations of giant Canada geese following nest destruction. We captured 3 adult nesting …
Noteworthy Winter Prey Of Short-Eared Owls In Southern Texas: A Case Study, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa
Noteworthy Winter Prey Of Short-Eared Owls In Southern Texas: A Case Study, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa
The Prairie Naturalist
The winter range of North American short-eared owls (Asio flammeus) encompasses much of the United States, including southern Texas, where it is a common winter resident (Oberholser 1974, Rappole and Blacklock 1985). Winter food habits of short-eared owls are relatively weJl documented, but the majority of investigations have been conducted in eastern Canada and northeastern U.S. (Clark 1975, Holt 1993); midwestern U.S. (Colvin and Spaulding 1983); and British Columbia and Pacific northwestern U.S. (Bogiatto et al. 2001). The short-eared owl has a narrow trophic niche, generally preying on small mammals, with voles (Microtus spp.) and deer mice …
Monitoring Meadows With A Modified Robel Pole In The Northern Black Hills, South Dakota, Daniel W, Uresk, Daryl E. Mergen, Ted A. Benzon
Monitoring Meadows With A Modified Robel Pole In The Northern Black Hills, South Dakota, Daniel W, Uresk, Daryl E. Mergen, Ted A. Benzon
The Prairie Naturalist
We used a modified Robel pole to measure vegetation for a study conducted in the northern Black Hills, South Dakota. Objectives were to determine the relationship between visual obstruction readings and clipped standing herbage, and develop guidelines for monitoring standing herbage. The relationship between visual obstruction readings and standing herbage was linear and regression coefficients were significant (P≤ 0.001). Herbage ranged from 140 to 3313 kg· ha-1 with a mean of 1386 kg· ha-1 (SE = 320 kg· ha-1) for 123 transects. Visual obstruction readings (VOR) ranged from 0.6 to 30.4 (number of 1.27 cm bands …
A Partial Inventory Of Islands In North Dakota: Potential For Breeding Waterfowl Management, Michael L. Szymanski
A Partial Inventory Of Islands In North Dakota: Potential For Breeding Waterfowl Management, Michael L. Szymanski
The Prairie Naturalist
Islands can provide secure nesting habitat for ducks and other waterbirds, especially in agriculturally dominated landscapes. I inventoried natural and man-made islands in the portion of North Dakota covered by the Prairie Pothole Joint Venture (PPJV). I mapped 1,305 islands in this area; up to 46% of which could provide enhanced nest success with management (e.g., predator removal or establishment of brushy cover). Management of islands for breeding ducks may be an important method for achieving desired reproductive rates in the PP JV as substantial areas of perennial grass cover are lost from federal conservation programs, primarily the Conservation Reserve …
Observations Of Badgers Preying On Black-Tailed Prairie Dogs, Daniel S. Licht
Observations Of Badgers Preying On Black-Tailed Prairie Dogs, Daniel S. Licht
The Prairie Naturalist
American badgers (Taxidea taxus) often visit black-tailed prairie dog (Cynomys ludovicianus) colonies, most likely in search of prey (Lomolino and Smith 2004, Shaughnessy and Cifelli 2004). Badgers are well suited to hunting fossorial prey such as prairie dogs by excavating burrows and capturing individuals belowground (Lindzey 2003). However, the ecological literature is sparse regarding details of how badgers hunt and capture prairie dogs underground. Eads and Biggins (2008) documented three occurrences of a badger excavating prairie dogs. That badger (apparently the same individual) had a den within the prairie dog town where captures occurred. This note …
Mortality Of Cranes (Gruidae) Associated With Powerlines Over A Major Roost On The Platte River, Nebraska, Gregory D. Wright, Timothy J. Smith, Robert K. Murphy, Jeffery T. Runge, Robert R. Harms
Mortality Of Cranes (Gruidae) Associated With Powerlines Over A Major Roost On The Platte River, Nebraska, Gregory D. Wright, Timothy J. Smith, Robert K. Murphy, Jeffery T. Runge, Robert R. Harms
The Prairie Naturalist
Two 69-kilovolt powerlines spanning the Platte River in south central Nebraska are suspected to cause substantial mortality to sandhill cranes (Grus canadensis) and pose a threat to endangered whooping cranes (G. americana) that roost overnight on the river during spring and fall migrations. Most studies of crane collisions with powerlines in the region have focused on counts of carcasses away from night roosts on the river and none have accounted for potential biases in detecting carcasses. We found 61 carcasses of sandhill cranes below over-river segments of the two powerlines during 4 March to 7 April …

Bed Site Selection Of Fawn Pronghorn In Custer State Park, South Dakota, Chad P. Lehman, Jamin D. Hartland, Barbara J. Keller, Joshua J. Millspaugh, Gary C. Brundige
The Prairie Naturalist
We evaluated pronghorn (Antilocapra americana) fawn bedding site characteristics on a prairie and ponderosa pine (Pinus ponderosa) landscape interface in Custer State Park, South Dakota. We radio-marked 16 adult female pronghorn and collected bed site information from their fawns during 2007~2008. We compared bed site selection with random sites (n = 74) during 2 periods; the early hiding phase when fawns were 1 ~28 days of age (n = 23 bed sites) and the later group phase when fawns were 29~60 days of age (n = 52 bed sites). During the hiding phase fawns selected dry …

Biofuels: Cultivating Energy, not Invasive Species, approved by ISAC on August 11, 2009
ISSUE
To provide alternatives to petroleum-based energy, the United States government has mandated a greater proportion of plant-based biofuels be integrated into its energy portfolio. However, certain plant species being proposed for biofuel production in the United States are invasive species or are likely to escape cultivation and become invasive. United States Executive Order (EO) 131121 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states: “Each Federal agency whose actions …

Since 1979, North Dakota's bird records committee has collected, evaluated, and archived documentations of rare bird occurrences in the state. In 2004 and 2005, this committee resolved 189 rare bird records. On the basis of these record reviews, six species were ad~ed to the North Dakota state bird list: mottled duck (Anas fulvigula), yellow-billed loon (Cavia adamsii), white-tailed kite (Elanus leucurus), little stint (Calidris minuta), glaucous-winged gull (Larus glaucescens), and great black-backed gull (Larus marinus). Four species were added to the list of nesting species within the state: snowy …
Effect Of Drought And Agriculture On Ring-Necked Pheasant Abundance, Nebraska Panhandle, Charles J. Randel Iii
Effect Of Drought And Agriculture On Ring-Necked Pheasant Abundance, Nebraska Panhandle, Charles J. Randel Iii
The Prairie Naturalist
The objectives of my study were to detennine the effects of drought (e.g., Palmer Modified Drought Severity Index; PMDI, Bridges et at. 2001) and/or agricultural practices (e.g., conversion) on RNP abundance in the Nebraska Panhandle (NP).
My RNP survey data were found to be correlated negatively to drought condition (PMDI) in January, February, and April. This was supported by Snyder (1984) and Riley (1995), both of whom reported that decreased precipitation in spring affected RNP production in the western Great Plains and Iowa, respectively. Late winter and early spring drought affect subsoil moisture and decrease primary production (Kiesselbach et al. …

Farmers And Nature Conservation: What Is Known About Attitudes, Context Factors And Actions Affecting Conservation?, Johan Ahnström, Jenny Höckert, Hanna L. Bergea, Charles A. Francis, Peter Skelton, Lars Hallgren
Department of Agronomy and Horticulture: Faculty Publications
Farmers’ attitudes towards viability of specific conservation practices or actions strongly impact their decisions on adoption and change. This review of ‘attitude’ information reveals a wide range of perceptions about what conservation means and what the impacts of adoption will mean in economic and environmental terms. Farmers operate in a tight financial situation, and in parts of the world they are highly dependent on government subsidies, and cannot afford to risk losing that support. Use of conservation practices is most effective when these are understood in the context of the individual farm, and decisions are rooted in land and resource …
Common Raven Nests In North Dakota After 100-Year Hiatus, Melvin P. Nenneman, Todd A. Grant, Ron E. Martin
Common Raven Nests In North Dakota After 100-Year Hiatus, Melvin P. Nenneman, Todd A. Grant, Ron E. Martin
The Prairie Naturalist
Our observations represent the first documented nesting by the common raven in North Dakota since the late 1800's. Houston (1977) suggested that the expansion of the American crow onto the Canadian prairies was limited by the scarcity of trees for nest sites, which also might have limited the extent of the common raven. Aspen woodland has increased substantially in and around J. Clark Salyer National Wildlife Refuge since European settlement, due primarily to fire suppression and extirpation of large herbivores (Grant and Murphy 2005). Thus, plausibly these increases in woodland habitat might be providing nest sites necessary for the common …
Factors Associated With Duck Use Of Impounded And Natural Wetlands In Western South Dakota, Jane E. Austin, Deborah A. Buhl
Factors Associated With Duck Use Of Impounded And Natural Wetlands In Western South Dakota, Jane E. Austin, Deborah A. Buhl
The Prairie Naturalist
Many wetlands in the northern Great Plains west of the Missouri River are stock ponds, created by impoundment of natural drainages or excavation of existing wetlands to provide water for livestock or improve habitat for waterfowl. We evaluated factors influencing use of wetlands by breeding duck pairs and broods relative to modification, water regime, size, and hydrological location on United States Forest Service lands within the Grand River National Grassland in northern South Dakota (2003 and 2004). Responses for both indicated pairs and broods were related positively to wet area, total wetland area within 4 km, emergent edge cover, and …

Brood Parasitism In A North American Population Of White-Faced Ibis, Mark E. Clark
The Prairie Naturalist
In 2007 while monitoring reproductive success among various overwater nesting birds at J. Clark Salyer National Wildlife Refuge in North Dakota, I observed parasitism of a white-faced ibis nest by a cattle egret. I located a nest on 23 May 2007 that contained four white-faced ibis eggs and one cattle egret egg. The nest was located in the middle of a small colony of nesting white-faced ibis (approximately 35 pairs) and black-crowned night herons (approximately 30 pairs). On 3 June 2007 all of the eggs were still present in the nest, but two of the white-faced ibis eggs began hatching …
