Fall Field Report, August-November 2020, W. Ross Silcock

Nebraska Bird Review

Two issues were of concern this fall, and both appeared to have consequences or at least similarities in Nebraska. A major die-off in New Mexico made national news: https://www.aba.org/the-data-behind-mysterious-bird-deaths-in-new-mexico/. On Sep 9, 2020, the temperature dropped from 96°F to 40°F in the Albuquerque area, a record low, winds reached 70 mph, and several inches of snow fell, killing large numbers of birds directly. Over the next few days, hundreds more dead birds were picked up. Some have linked this high mortality to birds displaced from the mountains due to fire and unfortunately being caught in the severe weather. While fire …

History Of The Seward-Branched Oak Lake Christmas Bird Count, 1993-2020, Joseph A. Gubanyi Dec 2020

History Of The Seward-Branched Oak Lake Christmas Bird Count, 1993-2020, Joseph A. Gubanyi

Nebraska Bird Review

The Seward-Branched Oak Lake Christmas Bird Count (Seward-BOL CBC) began in 1993 and has been conducted every year since then except for 2010 for a total of 27 counts. Weather conditions prevented the count on the selected date in 2010 and a backup date could not be set up. The count was started for several reasons. The area west of Lincoln has a diversity of habitats including all or part of four public lakes (Branched Oak, Pawnee, Twin Lakes, and Meadowlark) as well as a diversity of terrestrial habitats on both public and private land. The circle is close to …

Summer Field Report, June-July 2020, W. Ross Silcock Sep 2020

Summer Field Report, June-July 2020, W. Ross Silcock

Nebraska Bird Review

Overall, this was a fairly routine summer although birders in Nebraska know that “routine” still holds promise of a few happenings out of the ordinary. The summer season primarily examines new breeding records, range expansions, and changes in numbers, up or down. Mississippi Kites were conspicuous, a pair providing Scottsbluff’s first breeding record, but a repeating pair in Lincoln, Lancaster lost its nest in a windstorm. The first nesting record for Violet-Green Swallow for Sheridan, 7th nesting for White-winged Dove, and 9th for Short-eared Owl were all encouraging, as was an apparent family group of Northern Saw-whet Owls in Sioux. …


Robert Wolcott And The Art Of Nest Records, Thomas E. Labedz Sep 2020

Robert Wolcott And The Art Of Nest Records, Thomas E. Labedz

Nebraska Bird Review

The autumn of 1894 was fortuitous for Nebraska ornithology because it is when Robert Henry Wolcott accepted an assistantship at the University of Nebraska, moving to Lincoln from the University of Michigan (Swenk 1935). Wolcott, from that point onward, made significant contributions to our knowledge of Nebraska birds (Bruner et al. 1903, Wolcott 1909, 1919), was a founding member of the Nebraska Ornithologists’ Union (NOU), and was editor for the first three Proceedings of the NOU from 1899-1902. His work expanded beyond local focus and he eventually authored a text on animal biology (Wolcott 1933). The topic of this paper, …

Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray Aug 2020

Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray

Electronic Theses and Dissertations

After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect …

2019 (31st) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists’ Union Records Committee (NOURC) are described in its bylaws (NOURC 2010). 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. Species for which the NOURC seeks documentation (NOURC Review List) can be found at the NOU website www.NOUbirds.org. Starting in 2020, the NOURC will deal mainly with those species deemed as Accidental on the “Official List of the Birds of Nebraska”. Casual species and out-ofrange species will continue to be summarized in the “Seasonal Reports” of the …


Window Strike Bird Mortality On The University Of Nebraska – Lincoln City Campus, Thomas E. Labedz Jun 2020

Window Strike Bird Mortality On The University Of Nebraska – Lincoln City Campus, Thomas E. Labedz

Nebraska Bird Review

On May 25, 1915, in Lincoln, Lancaster County, Nebraska, a Gray-cheeked Thrush was “killed by flying against the library building on city campus” and was found by Robert H. Wolcott and prepared as a scientific study skin by Leroy M. Gates. This thrush is now ZM-6674 in the University of Nebraska State Museum (UNSM) Zoology collections. Birds are typically killed at low level buildings by flying into windows. This thrush is the first documented window strike death for what is now the University of Nebraska – Lincoln city campus. Based upon the UNSM bird collections I report on the last …

Feeding Ecology, Behaviour And Habitat Utilization Of Black Drongo (Dicrurus Macrocercus) In Pothwar Plateau, Pakistan, Muhammad Bilal, Zeeshan Khalid, Ali Hasnain Mosvi, Amir Naseer

Journal of Bioresource Management

Black Drongo is an insectivorous bird native to Pakistan. The present study focused on its feeding preferences, behaviour, ecology and habitat relationships. The study was carried out from first week of December, 2019 to the second week of April, 2020 in the two villages of Rawalpindi named as Daultala (Location-I) and Nata Gujarmall (Location-II). Observations were made by point count method on foot using line transect method. Air (52.27%) was the most commonly used feeding substrate. Aerial feeding mode (52.27%) is preferred over plant or tree gleaning (n=58) and ground feeding (n=47). Most common perching site was man made obstacle, …


Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow May 2020

Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow

Electronic Theses and Dissertations

Avian facial plumage, bill coloration, and feather microstructure may serve one or more adaptive functions. Several researchers have proposed that dark eyestripes, bills, and facial masks aid in reducing glare, however, there have been relatively few tests of this hypothesis. Dark facial markings have been shown to have an adaptive glare-reduction function in recent field studies of a few species, but this hypothesis has never been tested in a broad multispecies analysis. It is likely that feather microstructure influences feather brightness and has an effect on the efficacy of glare reduction properties of feathers. I examined the link between dark …


What Roadkills Did We Miss In A Driving Survey? A Comparison Of Driving And Walking Surveys In Baldwin County, Georgia, Kori A. Ogletree, Alfred J. Mead Apr 2020

What Roadkills Did We Miss In A Driving Survey? A Comparison Of Driving And Walking Surveys In Baldwin County, Georgia, Kori A. Ogletree, Alfred J. Mead

Georgia Journal of Science

Accurate estimates of vertebrate road mortalities are necessary prior to the consideration of mitigation measures by resource managers. Due to ease of implementation, driving surveys are more common than walking surveys. From February 2018 to February 2019, two survey methods, driving and walking, were used to monitor a 1.16 km section of Highway 212 in Baldwin County, Georgia. Roadkills were identified and monitored for persistence from sunrise to noon two days a week. Twenty-nine roadkills were recorded over the survey period: 48.3% mammals (14/29), 27.6% herpetofauna (8/29), and 24.1% birds (7/29). Forty-eight percent (14/29) of roadkills were missed by the …


Long-Term Changes In Avian Capture Rates During Twelve Years Of Active Grassland And Savannah Restoration, Katie Stumpf, Charles Muise Mar 2020

Long-Term Changes In Avian Capture Rates During Twelve Years Of Active Grassland And Savannah Restoration, Katie Stumpf, Charles Muise

Georgia Journal of Science

The decline of grassland ecosystems throughout the United States has caused population declines of many bird species, especially grassland specialists, which has led to greater interest in restoring these dwindling habitats with a combination of natural fire regimes and the replanting of native vegetation. In the southeastern United States, several species of birds use grassland habitats at critical points throughout the annual cycle, as breeding or wintering grounds or as migration stopover sites. Since April 2007, we have operated 9–11 mist nets at Panola Mountain State Park, in Rockdale County, Georgia, in an area that is being actively restored to …


2019-2020 Christmas Bird Counts, Don Paseka Mar 2020

2019-2020 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Mergansers reached a new high of 104 counted in nine circles, which topped the count of 97 from 2017. A single Surf Scoter was found in the Lower Platte circle, which was only the fourth time that this species has been found on a Nebraska CBC. Lone birds were also found at Lake McConaughy in 1999, 2010 and 2015. A good North Platte find were two Barrow’s Goldeneye. Several species, however, were counted in numbers much below the norm. The lone Wood Duck found at Branched Oak was the lowest count for that species since 2004, when they were missed …

Winter Field Report, December 2019-February 2020, W. Ross Silcock

Nebraska Bird Review

As with any of these Seasonal Reports, there was plenty to entertain us and to contemplate this winter. The most obvious feature of this winter’s reports was the taxonomically widespread incidence of midwinter occurrences of species normally absent at that time. Snow, Ross’s, and Greater White-fronted Geese occurred in good numbers, and Jan to early Feb reports of dabbling and diving ducks often far from expected winter occurrence locations were notable. Among passerines, notable midwinter reports were of Gray Catbird, Brown Thrasher, and Northern Mockingbird, Nebraska’s first record for Feb of American Pipit, and 6th winter record of Lesser Goldfinch. …

Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone Feb 2020

Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone

International Journal of Speleology

Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus, pose significant threats to vulnerable cave resources. Caves, with their nearly constant and predictable physical environment often house important natural and cultural features including biological, paleontological, geological, climatic, mineralogical, cultural, and archaeological resources. All four invasive rodents in Hawai‘i commonly nest in cave entrances and rock shelters, but only the roof rat (Rattus rattus) habitually enters caves and utilizes areas …


The Effects Of Dietary Linoleic Acid And Hydrophilic Antioxidants On Basal, Peak, And Sustained Metabolism In Flight‐Trained European Starlings, Wales A. Carter, Kristen J. Demoranville, Barbara J. Pierce, Scott R. Mcwilliams Feb 2020

The Effects Of Dietary Linoleic Acid And Hydrophilic Antioxidants On Basal, Peak, And Sustained Metabolism In Flight‐Trained European Starlings, Wales A. Carter, Kristen J. Demoranville, Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Dietary micronutrients have the ability to strongly influence animal physiology and ecology. For songbirds, dietary polyunsaturated fatty acids (PUFAs) and antioxidants are hypothesized to be particularly important micronutrients because of their influence on an individual's capacity for aerobic metabolism and recovery from extended bouts of exercise. However, the influence of specific fatty acids and hydrophilic antioxidants on whole‐animal performance remains largely untested. We used diet manipulations to directly test the effects of dietary PUFA, specifically linoleic acid (18:2n6), and anthocyanins, a hydrophilic antioxidant, on basal metabolic rate (BMR), peak metabolic rate (PMR), and rates of fat catabolism, lean catabolism, and …

Insights About Diversity Of Tetrabothriidae (Eucestoda) Among Holarctic Alcidae (Charadriiformes): What Is Tetrabothrius Jagerskioeldi?, Eric P. Hoberg, Kaylen Marie Soudachanh

MANTER: Journal of Parasite Biodiversity

Tetrabothriid cestodes are characteristic helminths that infect species of seabirds globally. We begin with the exploration of the diversity of tapeworms of the genus Tetrabothrius Rudolphi, 1819 (Eucestoda: Tetrabothriidae), some of which are distributed among seabirds of the family Alcidae (Charadriiformes) at boreal to higher latitudes of Holarctic seas. During the course of 2 decades of field inventory from 1975 through the early 1990s (in addition to earlier collections assembled by Robert L. Rausch and colleagues in Alaska initiated in the late 1940s), an extensive series of tapeworm specimens attributable to species of Tetrabothrius was recovered from seabirds across the …

Spring Field Report, March-May 2020, W. Ross Silcock

Nebraska Bird Review

Although there were numerous early arrival dates, most were in the range of historically earliest expected dates; notable, however, was a lone record-early Whiterumped Sandpiper, nicely photographed. Record late by a month was a juvenile Redtailed (Harlan’s) Hawk, also confirmed by photo. Perhaps most prominent this spring were the large numbers of several species. Most eye-popping were record spring totals of 22 Glossy Ibises, 11 Yellow-bellied Flycatchers, 14 Veeries, including five in the Panhandle, 48 Gray-cheeked Thrushes, 20 Bay-breasted Warblers, not long ago a rare bird in spring, 45 Golden-winged Warblers and 27 Canada Warblers, both of which were about …

The Evolution Of Dragons, Laura J. Mayfield Jan 2020

The Evolution Of Dragons, Laura J. Mayfield

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Dragons have been depicted in human art as early as 4500 BCE. For centuries, these fantasy creatures have inspired countless folk and fantasy tales, as well as appearing in the art of different cultures around the world. Now there are thousands of different depictions of these huge, flying, fire-breathing lizards, but are any of them possible? In this study, I reference peer-reviewed scientific articles, phylogenetic analysis, and paleoart studies to create biologically-sound dragons. Basing the dragon lineage on a real branch of webbed-winged scansoriopterygids—an extinct family of climbing and gliding maniraptoran dinosaurs—I explored the possible wing-structure, fire-breathing abilities, and effects …
