Avian Species Abundance In Response To Recreational Trail Use, Carrie A. Wencel

Department of Environmental Studies: Undergraduate Student Theses

Studies have indicated that non-consumptive outdoor recreation may affect wildlife. Thus, as the nation increases interest in outdoor recreation, data suggests the effect on wildlife will also increase. Previous studies indicate that as disturbance to wildlife increases, both avian species richness will decrease. Knowing how to anticipate effects on native species when planning and managing recreational areas is important in order to both provide for human desires and ensure the least impact to local species diversity.

The goal of this project was to observe and compare avian species richness and diversity between selected trail sites within Shevlin Park, Bend, Oregon …

Fall Field Report, August–November 2011, W. Ross Silcock

Nebraska Bird Review

Overall, this fall migration was routine (waterfowl, warblers, sparrows), but there were a few unexpected highlights. The flooded Missouri River Valley provided habitat that led to some amazing fall counts: 3000 pelicans, 5700 coots, 338 American Golden-Plovers, and 1200 Pectoral Sandpipers. The 10,000 cormorants at Harlan County Reservoir may not have been affected by the Missouri River flooding, and were a record count also. While we're talking numbers, the martin roost in Omaha topped out at 50,000–55,000, and seasonal totals of 4 Red-necked Grebes and 15 Philadelphia Vireos for the state, 34 Mississippi Kites over Ogallala (it's often hard to …

First Documented Nebraska Sighting Of Brown-Headed Nuthatch (Sitta Pusilla), Larry Einemann

Nebraska Bird Review

Monday, November 8, 2010, was an unusually warm (upper 70s) autumn day for Lincoln, Nebraska, with no clouds and a wind from the southwest. I went to Holmes Lake Park in southeast Lincoln to scan for late migrating waterfowl and then to check the stand of conifers for the arrival of winter migrants. Around 11 A.M. I was attracted to a feeding group of six Black-capped Chickadees and three Red-breasted Nuthatches in the 30- to 40-year-old pines and Douglas firs north of Hyde Observatory. I noticed a differently patterned nuthatch in the group. I had seen a Pygmy Nuthatch several …

Rocky Mountain Birds: Birds And Birding In The Central And Northern Rockies, Paul A. Johnsgard

Zea E-Books Collection

“The Rocky Mountain region has fascinated me ever since I traveled to Glacier and Yellowstone National Parks as a teenager, and saw for the first time such wonderful birds as ospreys, American dippers, and Lew­is’s woodpeckers.”

This book is in part based on the author’s earlier Birds of the Rocky Moun­tains (1986, revised 2009), but over a third of the original text has been eliminated. The rest has been updated, expanded and modified to be less technical and more useful to birders in the field. Bird enthusiasts will find viewing loca­tions and updated contact information for hundreds of sites in …

Summer Field Report, June–July 2011, W. Ross Silcock

Nebraska Bird Review

The effects of major drought in the southwest United States on bird life in Nebraska has yet to be determined, as has the effect of the historic inundation of the Missouri River bottom lands from Gavins Point Dam to Rulo in eastern Nebraska. The water level at McConaughy is coincidentally at a maximum, ensuring that breeding habitat for Piping Plover and Least Tern was much reduced in the state overall. On the other hand, bottom lands wetlands above the flood level were expanded; Black-necked Stilts initiated a late nesting in Dakota Co in flooded fields that also attracted thousands of …

2011 Bald Eagle (Haliaeetus Leucocephalus) Statewide Nesting Survey, Joel G. Jorgensen, Lisa Yager, Lauren R. Dinan

Nebraska Bird Review

The Bald Eagle (Halioeetus leucocephalus) was extirpated as a breeding species in Nebraska for most of the 20th Century. Nebraska's first active, successful, modern Bald Eagle nest was near Valley, Douglas County, in 1991 (Farrar 1991). Jorgensen et al. (2010) summarized modern Bald Eagle nesting records in Nebraska from 1950 to 2009. Jorgensen et al. (2010) noted the highest annual count of active nests was 54 in 2007. In this note we summarize the 2011 Bald Eagle nesting records in Nebraska.

Spring Field Report, March 2011 To May 2011, W. Ross Silcock

Nebraska Bird Review

There was a nice mix of interesting phenomena this spring, notably a big influx of migrant warblers. Species that are normally uncommon were reported in good numbers, 30 or more each: Chestnut-sided, Magnolia, Blackburnian, Palm, and Northern Waterthrush, and species that normally occur in very low numbers approached double digits: Blue-winged, Golden-winged, Cape May, and Baybreasted. Southeastern species continue to expand in se. Nebraska, notably Cerulean and Kentucky Warblers and Summer Tanager. A few rarities showed up, most spectacular an alternate-plumaged female Red Phalarope, the first such record for Nebraska, which was captured on video by Nebraska Non-Game TV. Other …

High Species Count At Annual Sarpy County Spring Bird Count, Clem Klaphake

Nebraska Bird Review

On May 14, 2011, participants in the Annual Sarpy County Spring Bird Count tallied 174 species, besting the previous high count of 143 (in 2006 and 2010) by 31 species. There were a few more counters this year than in most previous years, but it was just a good year for many families of birds. There were 28 warbler species seen (previous high was 23 in 2008). Also found were 4 terns, 9 flycatchers, 7 woodpeckers, 12 ducks, 14 shorebirds and 3 grebes. There are often unusual species that show up on the count, as illustrated by a Eurasian Wigeon …

Eurasian Wigeon In Sarpy County, Nebraska, Mark Brogie

Nebraska Bird Review

On Saturday 14 May 2011 on the Sarpy County Spring Count, Justin Rink, Jim Ducey, Ellen Brogie, and I found a Eurasian Wigeon at LaPlatte Bottoms. When first discovered the bird was in the company of multiple Gadwall and at least one adult male American Wigeon. The bird was a striking adult male bird with a rusty red head and a yellowish forehead. The breast was reddish and contrasted with the gray back and sides. This coloration made the white wing stripe more pronounced than that of the American Wigeon. The bird showed no evidence of hybridization. Multiple observers viewed …

Assessing The Stability, Biological Transfer And Developmental Impact Of Environmentally Relevant Nitrosamines Using A Chicken Egg Model, Nikita Joshi

Environmental Health, Occupational Health, and Toxicology: Dissertations and Student Research

Nitrosamines comprise a large group of potentially toxic compounds occurring in the environment as by-products of various manufacturing, agricultural and natural processes. Nitrosamines are produced from reaction of nitrite with a suitable secondary amine in an acidic matrix; these acidic conditions can occur in environmental media and in the mammalian gastrointestinal (GI) tract. This research focused on the stability, transfer, and impacts of the environmentally relevant nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosmorpholine (NMOR), and N-nitrosoatrazine (NNAT) (formed from reaction of nitrite with dimethylamine, morpholine, and atrazine), using the chicken egg and embryo model systems. Chicken eggs were used to …

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …

A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps

Nebraska Bird Review

The breeding range of the Summer Tanager (Piranga rubra) is well documented and expands across the southern U.S. extending northward to New Jersey and west along and south of the Great Lakes to the eastern edge of the Great Plains (Terres 1991; Robinson 1996). In Nebraska the species is generally confined to the Lower Missouri and Platte River Valleys where it occurs locally (Sharpe et al. 2001). Because the species exists in relatively low numbers across southeastern Nebraska, there are few breeding and nesting records for the state. Fewer than 10 breeding records, including one historical account have …

Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock

Nebraska Bird Review

Nebraska birders might remember seeing reports posted to NEBirds a few years back by Cole Wild, a native Coloradan whose mother's family is from Nebraska. Cole took up birding at age 19, spurred by an earlier high school environmental science class that required identification of 100 species of birds. As with many of us, a brightly plumaged bird, in this case a Western Tanager, resulted in "the birdwatching gene" in Cole suddenly being "switched to the ON position." Soon after, Cole went on a "what the heck, I'll try it" field trip to see a Kelp Gull at Loveland Reservoir …

2010–2011 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Christmas Bird Counts were held in Nebraska in the 2010–2011 season. The Branched Oak–Seward count was canceled due to weather, but in comparison to last year, the weather was generally dry, mild, and cooperative. Even though open water was limited, the species associated with water were well represented, resulting in the highest total number of species (149) ever, easily topping the previous high count of 138 in 2001. In all, 17 species set new high counts, 5 tied previous highs, and the amazing Brown-headed Nuthatches stayed in Lincoln and were counted for the first time in Nebraska.

Twelve species …

Winter Field Report, December 2010 To February 2011, W. Ross Silcock

Nebraska Bird Review

This winter was pretty much a rerun of last, although perhaps not as severe; I could have used last winter's Introduction again. If there was an overall theme, it would be the widespread occurrences of species that would not be expected to linger into late December and January. Several species of waterbirds, notably Blue-winged Teal, scoters, Ruddy Duck, Common Loon, and Homed and Red-necked Grebes were in this category. Large numbers of Western Grebes were still at Lake McConaughy in early January, and surprisingly late individuals of Black-crowned Night-Heron and Plegadis ibis were located. Mourning Doves were in good numbers …

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda

Nebraska Bird Review

Don and Lillian Stokes are well known for their nature guides that cover a variety of subjects, from hummingbirds and beginner shorebird identification to reptiles and amphibians. Their original pair of Stokes Field Guide to Birds: Eastern Region and Western Region have remained popular among North American birders since their appearance in 1995. They were illustrated with photographs instead of the traditional paintings used in most field guides. The authors' latest book, The Stokes Guide to Birds of North America is essentially an entirely new and much improved version of these two guides. Instead of being split into two books, …
