Low Reproductive Success Of Mallards In A Grassland-Dominated Landscape In The Sandhills Of Nebraska, Johann A. Walker, Zach J. Cunningham, Mark P. Vrtiska, Scott E. Stephens, Larkin Powell

The Prairie Naturalist

The Sandhills of Nebraska comprise approximately 5,000,000 ha of native grassland interspersed with numerous groundwater-fed wetlands. A substantial population of the mallard (Anas platyrhynchos) nests in this region. Previous investigations of nest survival probability of ducks in the Sandhills have estimated surprisingly low rates of nest survival for a grassland-dominated landscape. These investigations were conducted on public lands and most nest searching took place near wetlands where activity of nest predators might be highest. We predicted that mallards would nest at varying distances from wetlands and that survival probability of a representative sample of duck nests would increase …

Breeding By The Snowy Plover In North Dakota And South Dakota, Carol Aron, Paul Van Ningten, Michael Rabenberg, Cheryl Jacobs, Greg Pavelka, Ricky D. Olson

The Prairie Naturalist

The snowy plover (Charadrius alexandrinus) is a small shorebird that breeds on unvegetated beaches along coastlines, rivers, and alkaline lakes. In North America, its breeding distribution extends along the coasts of California, Oregon, and southern Washington, where the population is listed as federally threatened (USFWS 1993), and an interior population occurs on wetlands in western and central states and central Mexico (Page et al. 1995). There have been rare breeding reports in Montana, Wyoming, and Saskatchewan (Page et al. 1995), but no documented breeding records in North Dakota or South Dakota. However, the United States Army Corps of Engineers reported …

Use Of Passive Integrated Transponders In Hatchling Texas Horned Lizards, Scott E. Henke

The Prairie Naturalist

The Texas horned lizard (Phrynosoma cornutum) is a Texas state-threatened species and acquisition of data related to the species' ecology is essential. To accomplish this task individual animals need to be marked. Many marking techniques are available for lizards, however the majority of techniques have been tested on adults only. Studies involving hatchling and juvenile horned lizards are scarce due to problems associated with marking and relocating individuals in these age classes. I demonstrated that injection of passive integrated transponders (PIT's) can safely be used as a marking method in young Texas horned lizards. Thirty-two captive bred hatchling lizards were …

Mortality Of An American Marten From An Off-Highway Vehicle, Joshua B. Smith, Jonathan A. Jenks

The Prairie Naturalist

While there are several reviews of the effects of OHVs and recreational activity on wildlife populations (Knight and Gutzwiller 1995, Joslin and Youmans 1999), most studies have focused on physiological (Creel et al. 2002) or behavioral (Van Dyke et al. 1986, Riley et al. 2003) responses to disturbance; none have addressed the potential for direct mortality. In 2005, we documented the death from an OHV of a juvenile, female American marten (F299) that had been radiocollared during a study documenting the distribution and abundance of American marten in the Black Hills, South Dakota (Smith 2007); the Institutional Animal Care and …

Sex-Specific Feeding Rates And Provisioning Of Fruit To Nestling Bell's Vireo, Greg H. Farley

The Prairie Naturalist

Provisioning of fruit to nestlings and possible sex-specific differences in feeding rate have not been reported for Bell's vireo (Vireo bellii; Brown 1993). While studying nesting ecology of Bell's vireo on Konza Prairie Biological Station, Geary and Riley counties, Kansas, I quantified feeding rate by sex and food type delivered to nestlings. Sex was determined by capturing adults with mist-nets and inspecting for a cloacal protuberance, as well as conducting behavioral observations of uniquely-marked individuals. Males sing regularly while moving around territories, as well as during incubation (Nolan 1960). I assigned "female" to the individual in these socially …

Notes On Black-Footed Ferret Detectability And Behavior, David S. Jachowski

The Prairie Naturalist

Despite over two decades of recovery efforts, the black-footed ferret (Mustela nigripes) remains one of the least understood and most critically endangered mammals in North America. Once extinct in the wild, over 2,400 captive-born individuals of black-footed ferret (hereafter referred to as ferret) have been released at 13 reintroduction sites ranging from northern Montana to Chihuahua, Mexico, since 1991. However, ferret populations currently are considered to be self-sustaining at only two sites in South Dakota and a single site in Wyoming (United States Fish and Wildlife Service 2006). To understand why ferret recovery is not succeeding at a …

Optimal Foraging In Eastern Fox Squirrel: Food Size Matters For A Generalist Forager, Robert Tatina

The Prairie Naturalist

Classical optimal foraging theory (OFT) predicts that an animal forages optimally when it chooses foods with the highest energy benefit or minimizes time searching for and handling food. r evaluated OFT by presenting eastern fox squirrel (Sciurus niger) multiple food items (i.e., sunflower seeds and • fruits) in various density combinations. When the choice was between foods of equal energy benefits but different costs, they chose forage items with greater costs, seemingly not foraging optimally. However, individuals showed a partial preference for food items which minimized search time, but not handling time. The eastern fox squirrel also was …

Fifty Common Birds of the Upper Midwest. Watercolors by Dana Gardner; text by Nancy Overcott. 2006. University of Iowa Press, Iowa City, Iowa. 106 pages. $34.95 (cloth).

What's the best way to interest a friend in bird watching? Buy them a field guide, a CD of bird songs, or take them out bird watching? All of these ideas might work, but another approach is to tell personal stories and draw pictures of common birds in yards, parks, and natural areas where they live; help them "get to know their neighbors with feathers." That's exactly what Dana Gardner and Nancy Overcott …

First Record Of Field Speedwell From South Dakota, Robert Tatina

The Prairie Naturalist

Veronica agrestis L. (field speedwell or green field speedwell), a member of the Scrophulariaceae, is a small, weedy, prostrate annual with blue or white flowers (Gleason and Cronquist 1991). Until recently, its distribution included most of the eastern half of the United States and the southern two-thirds of the Great Plains, but not South Dakota (http://plants.usda.gov/java/profile?symbol=VEAG &photoID=veag_001_avd.tif, accessed 5 February 2007). Neither the Great Plains Flora Association (1986) nor Van Bruggen (1996) includes this species in the flora of South Dakota; however, the former has it naturalized in southeastern Nebraska and in Iowa (Great Plains Flora Association 1986). In May, …

Occurrences Of Small Mammal Species In A Mixedgrass Prairie In Northwestern North Dakota,, Robert K. Murphy, Richard A. Sweitzer, John D. Albertson

The Prairie Naturalist

Documentation is limited for many species of vertebrates in the northern Great Plains, particularly northwestern North Dakota (Bailey 1926, Hall 1981). Here we report relative abundances of small « 450 g) species of mammals that were captured incidental to surveys of amphibians and reptiles at Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota from 1985 to 1987 and 1999 to 2000. Our records include a modest range extension for one species. We also comment on relationships of small mammals on the refuge to vegetation changes associated with fire and grazing disturbances.

Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.

The Prairie Naturalist

We quantified the use of black-tailed prairie dog (Cynomys ludovicianus) colonies as habitat for the burrowing owl (Athene cunicularia) in southwestern Kansas and southeastern Colorado. We used incidental sightings and breeding season avifauna surveys to document the presence of the burrowing owl on black-tailed prairie dog colonies, non-colonized rangeland, and cropland during the spring and early summer. Burrowing owl rarely was observed on noncolonized rangeland and cropland sites, and black-tailed prairie dog colonies appear to be used substantially as a habitat type for the burrowing owl in the region encompassing Cimarron and Commanche National Grasslands in …

Using Distance Sampling To Estimate Densities Of White-Tailed Deer In South-Central Minnesota, Michelle A. Larue, Clayton K. Nielsen, Marrett D. Grund

The Prairie Naturalist

Distance sampling is a method of estimating population abundance and density used by wildlife biologists for several species because of its advantages relative to other techniques. However, few wildlife biologists have used distance sampling to estimate abundance of white-tailed deer (Odocoileus virginianus). We describe a distance sampling technique used to estimate prehunt and post-hunt population densities of deer in Watonwan County, Minnesota. Estimates of white-tailed deer density were compared between distance sampling versus population modeling, and costs for distance sampling versus aerial surveys were determined. We drove 2,704 km during 24 spotlight surveys conducted from 21 October to …

Among his friends, Bob Randall will be remembered as a caring, gentle man. Bob was one of those rare individuals who had a keen awareness of everyone around him. In social settings, he would make sure that everyone was comfortable, and it was always clear that he was genuinely concerned about everyone. Those who knew him will greatly miss his gentle nature and enthusiasm for birds. He never got caught up in all of his achievements. He had a sense of balance to his life which was evident in his many interests including birding and bird banding, rocks and minerals, …

Marshes-In Photos And Words. Review Of Marshes: The Disappearing Edens By Bill Burt, Douglas H. Johnson

The Prairie Naturalist

Bill Burt has done it again. The author of two superbly illustrated books (Shadowbirds and Rare and Elusive Birds of North America) that were reviewed earlier in this journal, Burt has returned with another excellent book, this one focusing on marshes. Like his earlier books, Marshes features wonderful close-up views of many hard-to-photograph birds. Here, in addition, are grand images of marsh landscapes and other marsh denizens, especially plants. Burt best characterizes his own book, which he intends as "an evocation and exploration, rather than a catalog of marshland life." He tells of his 30 years spent prowling …

Silphidae (Insecta: Coleoptera) Collected In North Central North Dakota, Including New Occurrences Of Thanatophilus Sagax (Mannerheim),, Guy A. Hanley

The Prairie Naturalist

Members of the beetle family Silphidae are relatively large (10-35 mm) and often brightly colored insects. They usually are found in association with dead animal bodies (carrion), but some are phytophagous while others are predatory. Thirty endemic species are known to occur in North America north of Mexico (Ratcliffe 1996), and 17 species in North Dakota. (Hanley et aI., unpublished data). To date, there has been little to no silphid collection data available from north central North Dakota counties, due mostly to the lack of entomological research in the area.

Nine species of silphids were collected in a single season …

First Record Of Corisella Inscripta (Uhler) (Heteroptera: Corixidae) From North Dakota, Bruce A. Hanson, David M. Mushet, Ned A. Euliss Jr., Stephen Chordas Iii

The Prairie Naturalist

Corisella inscripta is a water boatman species that was reported in H. B. Hungerford's (1948) seminal monograph as occurring throughout Mexico and nine western states of the United States. Subsequently, additional records of C. inscripta have been reported for British Columbia in Canada (Maw et al. 2000) and for Montana (Roemhild 1976), Arkansas (Cochran and Harp 1990), Missouri (Polhemus et al. 1988), Ohio (Chordas and Armitage 1998), and Michigan (Chordas et al. 2002) in the United States. There have been no published records of C. inscripta from North Dakota (Fig. I). We collected one male C. inscripta at the Cottonwood …

Nancy Overcott has written series of short essays of birds found in the Upper Midwest and assembled them in an easy-to-read book. As an ornithologist and avid birder in this region, I'll admit that I didn't know what to expect when I opened the cover-would the focus be on rarities, would there be an identification component, are there tips for finding each species, and at what audience was the book aimed? Ultimately, I …

Vegetative Characteristics Of Pronghorn Bed Sites In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jonathan A. Jenks, Jaret D. Sievers, Daniel E. Roddy

The Prairie Naturalist

Much of the previous literature on pronghorn (Antilocapra americana) fawns has focused on fawn mortality (Beale 1978, Barrett 1984, Gregg et al. 2001) and social behavior (Kitchen 1974, Autenrieth and Fichter 1975, Bromley 1977). Selection of bed sites by pronghorn fawns is a major factor affecting fawn survival (Bromley 1978, Barrett 1981, O'Gara et al. 1986, VanSchmus 1990) because adequate cover is a crucial component of fawn bed site selection (Autenrieth 1984). Alldredge et al. (1991) reported that fawns selected dense shrub cover but avoided the most-dense cover in sagebrush-steppe communities in southcentral Wyoming while Tucker and Gamer …

Intraspecific And Interspecific Territoriality In Microtus Ochrogaster And M. Pennsylvanicus, David J. Tazik, Lowell L. Getz

The Prairie Naturalist

Adult female Microtus ochrogaster and M. pennsylvanicus displayed interspecific territorial behavior in a bluegrass site in Illinois. We concluded that within a site, interspecific territorial behavior might be a factor in non-synchronous population fluctuations characteristic of the two species.

Woodland Bird Use Of In-Channel Islands In The Central Platte River, Nebraska, William C. Scharf

The Prairie Naturalist

Recapture data showed woodland obligate birds from riparian habitats made substantial use of thinly vegetated, adjacent small islands in the Platte River. During the bird nesting and spring migration seasons of 200 I through 2004, there were 4,360 individuals of 90 species captured on both mainland and in: hannel island sites. Island locafion captures totaled 595 individuals of 47 species )etween 2002 and 2004. Islands formerly were considered inconsequential for coraging and nesting of passerines. My study substantiated passerine use of Islands and provided a rationale for additional consideration of islands for migration and nesting management. Assemblages of bird species …

Mallard Brood Movements In The Canadian Prairie Parklands, Garnet H. Raven, Todd W. Arnold, David W. Howerter, Llwellyn M. Armstrong

The Prairie Naturalist

We radiotracked 308 mallard (Anas platyrhynchos) broods from hatching until 30 days of age Oij 15 study areas located throughout the Canadian Prairie Parklands to examine patterns of variation in movement frequency and distance. Broods moved an average of 350 m from nests to first wetlands (SO = 390), with 94% of broods moving less than I km. After leaving the nest, broods had a 23% probability of moving to a new wetland each day, but movement probability was a complex function of study area, hatch date, and ducking age, with younger and earlier-hatched broods exhibiting greater movement …

Partial Characterization Of Two Moderately Halophilic Bacteria From A Kansas Salt Marsh, Aileen M. Johnson, Lance R. Thurlow, Sam R. Zwenger, Eric T. Gillock

The Prairie Naturalist

Two bacterial species were isolated from a salt marsh located on privately owned land in Russell County, Kansas. Water samples from the saIt marsh were streaked for isolation on tryptic soy agar supplemented with 12 % NaCI. Visual scanning of the plates revealed two prominent colony types. The two colony types were subcultured repeatedly until axenic cultures were obtained. 80th of these organisms were shown to be moderately halophilic. The organisms were characterized partially by fatty acid methyl ester analysis, 16S rRNA sequencing, and scanning electron microscopy. These studies revealed that the bacteria previously were unreported members of genera Marinococcus …

Population Biology Of Pumpkinseed In Enemy Swim Lake, South Dakota, Eric J. Weimer, Michael L. Brown

The Prairie Naturalist

Little information is available regarding the biology and population characteristics of pumpkinseed (Lepomis gibbosus), especially in South Dakota, a state at the western edge of the species native range. South Dakota Department of Game, Fish and Parks summer trap net survey data, collected 1998 to 2003, suggests the Enemy Swim Lake population has low abundance (0.4-2.9 per trap net night) and moderately high size structure (proportional stock density [PSD] ranges between 71 and 91). To further examine the biological characteristics of the Enemy Swim Lake population, pumpkinseed was collected from Indian Bay with trap nets during May 2003. …

Feeding Habitats Of Spring-Migrating Blackbirds In East-Central South Dakota, Richard S. Sawin, George M. Linz, William J. Bleier, H. Jeffrey Homan

The Prairie Naturalist

Between March 27 and April 21, 1998, we monitored blackbird (Icteridae) activity and habitat selection at a migratory staging area in east-central South Dakota. We used fixed-area observation points located within 20 l-km² circular plots centered on four wetland basins that were used as night roosts. Each roost was surveyed four times, with the surveys spread evenly throughout the blackbird migration. We recorded the number of blackbird flocks, flock size and composition, habitat used, and behavior (e.g., loafing and feeding). Fifty percent (n = 242) of the 482 flocks recorded in the quadrats was observed loafing in trees …
