Least Tern And Piping Plover Surveys Of The Central And Upper Platte River 2001–2004, Mark Czaplewski, Jim Jenniges, Mark Peyton

Nebraska Bird Review

Central Platte Natural Resources District (Central Platte NRD), Nebraska Public Power District (NPPD), and Central Nebraska Public Power and Irrigation District (Central) have been involved in monitoring and management of interior Least Tern (Sterna antillarum) and Piping Plover (Charadrius melodus) nesting habitat along the Platte River and on the shores of Lake McConaughy in Nebraska since the late 1980s. Since 2001, Central Platte NRD, NPPD, and Central have also helped implement the Least Tern and Piping Plover monitoring protocol developed by the Technical Advisory Committee of the Platte River Endangered Species Partnership (PRESP) (PRESP 2002a, an …

In Memory Of Loren ‘Bub’ Blake, Sept. 17, 1944-Oct. 5, 2004, Neal Ratzlaff

Nebraska Bird Review

Loren Blake, known to all of his friends as 'Bub,' entered many of our lives on a fall evening in the late 1980s. The occasion was the traditional shared nature slide session at the Nebraska Ornithologists' Union Fall Field Days. Rumors circulated about a Sandhills rancher interested in birds and photography who was going to show up with a few slides he had taken “around the ranch.” And show up he did, with a carousel of his best! The room was soon buzzing with Oohs, Aahs, and Wows as Bub dazzled us with his crisp, well-composed photos of everything from …

Northern Saw-Whet Owls: Rare Or Overlooked? An Example From The Central Platte Valley, Daniel H. Kim

Nebraska Bird Review

Assessing the population status for species requires accurate measures of local or regional numbers. For many species, standardized protocols exist for estimating local numbers through visual counts (e.g., Breeding Bird Survey routes, Christmas Bird Count circles, and point count protocols used by the US Forest Service). For many raptor species, monitoring populations at migratory bottlenecks such as the Goshute Mountains, NV, Hawk Mountain, PA, and Cape May, NJ, provide yearly indices of population health. Unfortunately, most monitoring protocols overlook a suite of small crepuscular or nocturnal species. Project Owlnet (www.projectowlnet.org) is a volunteer-based network of banding stations focusing on Northern …

Spring Field Report, March-May 2005, W. Ross Silcock

Nebraska Bird Review

As is often the case, the spring season had something for everyone: potential range expansions, an incredible shorebird migration through the eastern Rainwater Basin, a scarcity of migrant warblers, and some genuinely rare birds.

Timely spring rainfall transformed the Rainwater Basin, leaving large areas of sheetwater for migrant shorebirds and improving the attractiveness of wetlands, particularly renovated wetlands, to certain breeding species.

Perhaps the most important bits of information we can record here are changes in breeding ranges or behavior. Of significance here is the second nesting record for Hooded Merganser, the increasing occurrence of Greater Prairie-Chickens at Rainwater Basin …

2004 (16th) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists' Union Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. The "Official List of the Birds of Nebraska" was first published in 1988 (NOU Records Committee 1988) and has been updated two times (NOU Records Committee 1997, 2004).

The "Official List" has been appended fourteen times: (Mollhoff 1989, Grenon 1990, 1991, Gubanyi 1996a, 1996b, 1996c, Brogie 1997, 1998, 1999, 2003, 2004, Jorgensen 2001, 2002, 2003). This …

Playback Experiments Using Regional Duets And Solos: Territoriality In The Grey-Breasted Wood Wren In Eastern Andean Ecuador, Arathi Govind

Independent Study Project (ISP) Collection

In this study, playback experiments were conducted on the Grey-breasted Wood Wren, H. leucophrys, at Yanayacu Biological Research Station and Center for Creative Studies in Ecuador. This study was conducted in order to see how reactive the birds were towards duets from the area, solos from the area, and duets from other regions of the country. Pairs were expected to react more strongly towards duets than solos and familiar duets stronger than unfamiliar ones. Two different playback experiments were conducted. In the first experiment, six different pairs were chosen along with four different song types, a Yanayacu duet, a male …

2004-05 Christmas Bird Counts In Nebraska

Nebraska Bird Review

The addition of a new count encompassing Ponca State Park brings our total reported Nebraska counts to twelve this year. A total of 199 field counters and 20 feeder watchers participated. Temperatures were average, DeSoto being the cold spot, and precipitation was minimal.

This was the first year Cackling Geese were reported, following the recent split of Canada and Cackling Geese; a total of 70 were counted in 6 circles. American Wigeon numbers have been rising steadily on Nebraska CBCs, and the trend continued this year with 819 counted, a 25-year high. Three White-winged Scoters were found at Lake Mcconaughy, …

The 2003-2004 Nebraska Nest Report, Wayne J. Mollhoff

Nebraska Bird Review

Due to the fact that I was recalled to active duty by the US Army, I have been out of the state for the past two years. Hence, the number of observations made will be much abbreviated, and the usual comments on climatic conditions will be more limited.

A brief visit to the western Panhandle in June 2003 revealed that at least the southwestern Panhandle received enough rain to grow a crop of wheat, and there was more grass on the hills than in the previous several years. Despite this, some other parts of the state, especially the western Republican …

New Westward Breeding Records For Eastern Towhees In Central Nebraska, William C. Scharf

Nebraska Bird Review

The current breeding range of Eastern Towhees (Pipilo erythrophthalmus) in Nebraska is described as westward to a line from Cedar Co through Platte, Hall, and Harlan Cos (NBR 64: 124, Sharpe et al. 2001). Frequent recent sightings of Eastern Towhees during the breeding season have been made from more westward locations. A few reports are from Lincoln Co., 5 June 2004 by TJ Walker (NBR 72: 91), and Dawson Co., 13 May 2004 by Laurel Badura (NBR 72: 55). In contrast to the capture data presented here, none of the sightings is corroborated with breeding …

Habitat Associations Of Nebraska Birds, Paul A. Johnsgard, John Dinan

Nebraska Bird Review

In the fall of 2003 we set out to assign habitat associations to 363 species of birds that regularly occur in Nebraska for the purpose of evaluating the relative importance of each of Nebraska's major habitats to the state's breeding, migrating, and wintering birds. It is our hope that this information will (1) provide the first thorough investigation of Nebraska's birds and the habitats they use, and (2) provide a method for prioritizing the conservation of Nebraska's varied habitats for birds.

Winter Field Report, December 2004 To February 2005, W. Ross Silcock

Nebraska Bird Review

This winter was generally unremarkable except for the occurrence of good numbers of several species at the western edge of the state, notably Clark's Nutcracker, Pygmy Nuthatch, and Bohemian Waxwing. There were a couple of sightings of Mountain Chickadee and one of Cassin's Finch for good measure. All of the winter finches on the Nebraska list (except for Hoary Redpoll) appeared, most notably Pine Grosbeak, represented by two birds. One of these was in the southwest (Kansas had several reports) but the other was in the east, suggesting either multiple points of origin, or, as suggested by some in Kansas, …

Responses Of Coccidia-Vaccinated Broilers To Essential Oil Blends Supplementation Up To Forty-Nine Days Of Age, E. O. Oviedo Rondon, S. Clemente-Hernandez, P. Williams, R. Losa

Faculty Publications

Coccidiosis control may become a greater problem as the use of growth-promoting antibiotics (GPA) and ionophores declines. Vaccination with live oocysts may turn into a popular alternative to the use of coccidiostats in broilers, although cocci vaccination is frequently linked to temporary lower performance in young flocks. This experiment evaluates the dietary supplementation of 2 specific essential oil (EO) blends (Crina Poultry and Crina Alternate), either as alternatives to GPA and ionophores (BMD + Coban) or as feed additives that help to improve the performance of cocci-vaccinated broilers. Live performance and lesion scores were observed. These 2 specific EO blends …

Prediction Of The Tenderness Of Cooked Poultry Pectoralis Major Muscles By Near-Infrared Reflectance Analysis Of Raw Meat, Bradley R. Cheatham

Inquiry: The University of Arkansas Undergraduate Research Journal

Tenderness in boneless poultry breast meat is of utmost importance to consumers. However, there is currently no nondestructive method to predict poultry breast meat tenderness. Textural properties of poultry breast meat were predicted by near-infrared reflectance (NIR) spectroscopy. Spectra were collected on 390 poultry Pectoralis major muscles from broiler carcasses to examine the correlation between NIR spectroscopy and the Meullenet-Owens Razor Shear (MORS) test. Two instrumental parameters (maximum shear force and total shear energy) were used as estimates of meat tenderness. Calibration (R2 cal) and validation (r2 val) coefficients of determination were used for predicting instrumental measurements using the reflectance, …

Zur Nahrungsökologie Des Uhus Bubo Bubo In Der Mongolei = Feeding Ecology Of The Eagle Owl Bubo Bubo In Mongolia, Thomas Hoffmann, Michael Stubbe, D. Heidecke, R. Piechocki, R. Samjaa, J. Erfurt, D. Sumjaa

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper presents further results on the food ecology of the eagle owl in western Mongolia for the years 1984 to 1992. Additional to the already known sites we investigated two new resting places. At least 27 mammal and 17 bird species were recorded. The results confirm previous studies. Small to medium sized mammals (Cricetidae, Dipodidae, Arvicolidae) dominate the prey of the eagle owl whereas birds and invertebrates are less important.

Avifaunistische Beobachtungen Im Westchentej, Ulrich Zöphel, Jochen Schulenberg, Wolf-Dieter Busching, Ingolf Todte

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper reports the results of bird observations at four study sites with many different habitats in the western Chentej-mountains (forest steppe, taiga) at the end of the spring-migration and the beginning of the breeding time. Altogether 134 bird species were observed, about 107 of which are probably breeding birds. Additional birds were caught using 6 mist-nets. In this way 98 birds of 21 species were caught, measured, and ringed. Furthermore feathers have been collected (molting feathers and near two breeding places of Accipiter nisus).

The bird fauna of the larch forests shows a high species richness (108 species), …

Das Arteninventar Der Avifauna Der Mongolei Während Einer Nord-Süd-Durchquerung 1997, Tobias Stenzel, Michael Stubbe, R. Samjaa, Annegret Stubbe, C. Dulamsuren

Here we present a detailed report on bird biodiversity of ecosystems along a North-South transect through Mongolia in 1997whic h serves as a guideline for further research projects and training for students in all Mongolian vegetation zones from northern steppes to southern deserts.

Two hundred fifty-five bird species were observed between 21st of July and 10th of August 1997. The main study sites were located in the North the Selenge-Orchon-basin with meadows and dune woodlands 15 km southern from Suchbaatar, the Middle Gobi-Aimag with desert steppes and sajrs (covered with Ulmus pumila) and in the Bordzongijn-gobi in the South …

Über Die Federmerkmale Der Mongolischen Sakerfalken Falco Cherrug Milvipes Im Vergleich Zu Den Westlichen Sakerfalken Der Unterart F. Ch. Cherrug Und Bemerkungen Über Die Gefiedermerkmale Des “Altaifalken”, Wolf-Dieter Busching

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The different plumage characteristics of the Mongolian Saker Falco cherrug milvipes and the nominate race F. ch. cherrug are discussed. It could be shown that both races are polymorphic. According to Baumgart (1997), Sakers don’t need uniform plumages because they live on nearly blind voles. Due to that there seems to be no selection pressure from victims side. The same phenomenon is observable with Buteo buteo and the typical Mongolian Buteo hemilasius.

Whereas young Sakers of the nominate race cherrug equal more or less already adults, are the differences in the plumage of juv. and ad. milvipes great enough. …

The 2002 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry conditions surely …

Fall Field Report, August-November 2004, W. Ross Silcock

Nebraska Bird Review

The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.

Counts of interest were 3000 Double-crested …

Nebraska Bird Review

Addendum to Greater Snow Goose Article

In "The Greater Snow Goose (Chen caerulescens atlanticus) in Nebraska" by W. Ross Silcock, published in the Sept. 2004 issue of The Nebraska Bird Review, we failed to credit Randy Buettner of Grand Island, who made the original observation of the Greater Snow Goose and provided the specimen, which was obtained in Clay Co. and is shown in the photo, to William Lemburg.
