First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, Bartholomew L. Bly, Travis Wooten

Nebraska Bird Review

On 27 May 2010, the first documented Mountain Plover nest in Nebraska to contain a clutch of four eggs was documented in a fallow strip of a dryland crop field in southern Kimball County. Mountain Plover typically have a clutch size of 3 eggs, though clutches with 1 and 2 eggs are observed in approximately 15% of nesting attempts (Knopf and Wunder 2006). Clutches with 4 eggs are rare and have been reported to occur in less than 1% of the population (Knopf and Wunder 2006). Five 4-egg clutches have been reported in Colorado and one in Montana (see Knopf …

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 …

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 …

Fall 2011 Bird Banding At Wildcat Hills Nature Center, Colin Woolley

Nebraska Bird Review

Rocky Mountain Bird Observatory has been operating a fall migration bird banding station at the Wildcat Hills Nature Center in Scotts Bluff Co. since 2007. In 2011, during our fifth year of banding, we captured a few new species, had new high totals for other species, and had a record number new high total of recaptures. Weather permitting, we banded on weekdays from August 31 through October 10 for five hours per day beginning soon after sunrise. We caught and banded 735 individual birds of 32 species. We banded two new species for the station in 2011: one Red-eyed Vireo …

Detection Of Two Pathogens Of High Importance To The National Poultry Improvement Plan: Salmonella Spp. And Mycoplasma Spp., Robin Levi Jarquin

Graduate Theses and Dissertations

In 1935, the National Poultry Improvement Plan (NPIP) was created to control Salmonella gallinarum and Salmonella pullorum . These two pathogens were devastating economically for poultry producers. Through cooperative efforts using vaccination and strict biosecurity, these two pathogens were eradicated from the United States. Currently, the NPIP program is targeting two other poultry pathogens, Salmonella enterica serovar Enteritidis and Mycoplasma . In the broiler industry it targets 2 specific Mycoplasma species (synoviae, gallisepticum). Vaccinations for these bacteria are available, but are not fully effective at controlling all strains and serovars. Thus, constant monitoring systems and strict biosecurity measures are necessary …

Protein Utilization And Requirements In Broiler Breeders, Ricardo David Ekmay

Graduate Theses and Dissertations

Advances in the genetics of poultry have created unintended consequences to the broiler breeder industry. Excessive weight has been shown to have many negative effects, including double hierarchies, multiple ovulations, and fatty liver. In an effort to curb excessive body weight gain, both the protein requirements and feeding strategies of broiler breeders are being revisited. A series of studies were conducted to determine the protein and amino acid requirements of broiler breeders during the production phase and to determine the interrelationship between protein turnover and egg formation. In the first trial, a 2x3x3 factorial study was conducted to determine the …

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 …

Temporal Comparisons Of Avifauna In Enashiva Nature Refuge, Tanzania An Examination Of Species Richness And Abundance, The Effects Of The Onset Of The Short Rainy Season, And The Migrant Communities Present, Taran Catania

Independent Study Project (ISP) Collection

This study examined avian species richness, abundance, distribution, and diversity in relation to seasonal and temporal changes in Enashiva Nature Refuge, Tanzania. Data was collected in using point-counts along pre-established transects in four distinct habitats – wooded grassland, grassland, woodland, and riverine – over an 18-day period from November 6 to November 23, 2011. Transects were comprised of five point-count spots, at which data on avian species an abundance was collected for 30 minutes each. Data was compared to two previous studies conducted in November 2009 and April 2011 with similar methodologies over comparable time frames. Descriptive statistics, community similarity, …

Executive Summary, Cumberland County Foodshed Assessment, Report 1, Barbara Ives

Local Food Systems

Like everyone else in these troubled economic times, Mainers are looking for ways to create jobs that will remain relevant and vital in a global economy, that cannot be outsourced, and that will regenerate rather than exploit our natural resources.

A growing number of people believe that a food system rooted in local farms, fisheries, and food production and distribution enterprises can strengthen Maine’s economy and its communities’ health, thereby increasing revenue and decreasing an expense that is crippling government agencies and individuals alike – healthcare. Business people who want to make a living related to food, and public and …

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.

Phylogeography Of A Vanishing North American Songbird: The Painted Bunting (Passerina Ciris), Connie Ann Herr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Studies of genetic variation within and between species can provide insights into their evolutionary history as well as important information for conserving biodiversity. An understanding of population processes can assist in the conservation of biodiversity by contrasting current versus historical patterns, and the processes that have generated these patterns. Genetic differentiation often coincides with significant geological or climatic changes that have shaped the sizes and locations of the species geographic range and altered the connectivity between populations over time. Phylogenetic and population genetic analyses can also provide a statistical framework for the investigation of how human processes such as habitat …
