The Evaluation Of Genetic And Phenotypic Differences Associated With Short Term Selection Of Four Different Feed Efficiency Strategies In Japanese Quail, Alex David Gilley

Graduate Theses and Dissertations

The concept of feed efficiency (FE), one unit of feed required to improve one unit of desired output, is relatively simple. However multiple outputs are desired in a commercial poultry breeding program, resulting in the need for nutrients to be partitioned in a particular manner. At the broadest level, nutrients are partitioned between production and maintenance requirements. The requirements for production and maintenance varies between birds. It is the poultry breeder’s responsibility to select individuals most aligned with the breeding objective. Irrespective of the breeding objective, various related and non-related traits influence a bird’s FE. To effectively improve FE, the …

Stable Isotopes Reveal Opportunistic Foraging In A Spatiotemporally Heterogeneous Environment: Bird Assemblages In Mangrove Forests, Christina Buelow, April Reside, Ronald Baker, Marcus Sheaves

University Faculty and Staff Publications

Environmental heterogeneity can foster opportunistic foraging by mobile species, resulting in generalized resource and habitat use. Determining species’ food web roles is important to fully understand how ecosystems function, and stable isotopes can provide insight into the foraging ecology of bird assemblages. We investigated flexibility of food choice in mangrove bird assemblages of northeast Australia by determining whether species’ carbon and nitrogen isotopic values corresponded to foraging group classification described in the literature, such as groups of species that are omnivorous or insectivorous. Subsequently, we evaluated foraging group isotopic niche size, overlap, degree of individual specialization, and the probable proportions …

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

School of Natural Resources: Dissertations, Theses, and Student Research

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made …

An Observed Instance Of Cooper’S Hawk (Accipiter Cooperii) Predation On A Chicken In An Urban Environment, Don Arp Jr.

Nebraska Bird Review

On February 21, 2015, I had the opportunity to observe a Cooper’s Hawk (Accipiter cooperii) attack, kill, and feed on a chicken in an urban environment.

The attack occurred around 1:10 p.m. on February 21, 2015, in Lincoln, Nebraska, in a residential area that is often referred to as the Bethany neighborhood. With large mature trees and landscape hedges, it provided excellent cover for the hawk’s attack. Weather data for that day show a low temperature of 18 degrees Fahrenheit and a high temperature of 40 degrees Fahrenheit. There was residual snow cover in some areas, as Lincoln had experienced …

Possible Double-Brooding In Scissor-Tailed Flycatcher (Tyrannus Forficatus), Wayne Mollhoff

Nebraska Bird Review

In a follow-up visit to the site near Alexandria, Thayer Co., where I documented a Scissor-tailed Flycatcher nest with eggs in 2017, I found a pair present at the same site on 8 June 2018. After some searching, I found that their nest, with 4 eggs, was built in the same upright crotch of the same branch where it was located the year before. I knew it was a completely new nest, since the previous nest had been removed after the nesting season the year before. On a second visit on 13 August 2018, to see if the birds and/or …

Summer Field Report, June-July 2018, W. Ross Silcock

Nebraska Bird Review

This was a rather lackluster summer season, notably among waterfowl, shorebirds, and gulls. However, the discovery of a couple of amazing rarities spiced things up. Not only were there a few reports of the increasing Black-bellied Whistling- Duck, but the Fulvous Whistling-Ducks in Lancaster Co were a first state record, albeit a bit overdue. Another major rarity was a Reddish Egret, Nebraska’s third, in Hall Co, seen by almost as many folks as the Fulvous Whistling-Ducks. Close behind were the 6th and 7th Nebraska records of Black-chinned Hummingbird, probably on its way to regular occurrence in the next few years. …

Prevalent Transoceanic Fall Migration By A 30-Gram Songbird, The Bobolink, Noah G. Perlut

Environmental Studies Faculty Publications

Three North American passerines are known to perform transoceanic flights during their fall migration, with open-water flights ranging in length from 1,700 to 3,400 km. However, little is known about within-population variation of these flights. From 2013 to 2017, I used geolocators to study variation in the fall migratory track of the Bobolink (Dolichonyx oryzivorus) from a population that bred in agricultural grasslands of Vermont, USA. Thirteen of seventeen birds took transoceanic flights during fall migration, ranging in length from 1,098 to 3,536 km (mean ± SD = 1,969 ± 640); five of these flights were nonstop from …

Breeding Bird Response To Post Oak Savanna Restoration Seven Years Post Management In Eastern Texas, Courtney Mcinnerney

Electronic Theses and Dissertations

Oak savannas were once an abundant vegetation type in the Midwestern United States that have now declined to <1% of their original distribution. Historically, natural disturbances such as periodic fire and grazing maintained oak savannas, but these have been reduced or eliminated, resulting in woody encroachment and subsequent habitat loss and degradation. In 2009-10, a baseline, pre-restoration study was completed to determine vegetation characteristics, breeding bird abundances, nest success, and nest site selection at the Gus Engeling Wildlife Management Area (GEWMA) in eastern Texas. The results showed a lack of savanna vegetation structure on degraded sites and few savanna or grassland obligate bird species. The goal of this study was to determine how breeding birds of oak savanna vegetation types in eastern Texas respond to restoration effects 7 years after initial management. Post-restoration surveys completed in 2016-17 showed a change in avian assemblages from a more woodland dominated community to grassland/savanna community. The presence and breeding of savanna obligate species dickcissel (Spiza americana) and lark sparrow (Chondestes grammacus) indicates that the restoration was successful. The presence of savanna species can be linked to the herbaceous vegetation that was restored to more closely resemble historic oak savanna structure and can quantify the success of restoration efforts.

Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo

Environmental Studies Faculty Publications

Bobolinks (Dolichonyx oryzivorus) migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four Plasmodium lineages recently detected in resident Galapagos birds. We hypothesized that Bobolinks carried these parasites to Galapagos, where they were bitten by mosquitoes that then transmitted the parasites to resident birds. The haemosporidian parasite community in 44% of the Bobolinks we captured was consistent with those on their …

Age-Specific Differences In Fat Reserves And Migratory Passage Of Setophaga Striata (Blackpoll Warbler), Emily N. Filiberti, Noah G. Perlut

Environmental Studies Faculty Publications

Adequate fat reserves are vital for long non-stop transatlantic avian-migration movements, such as those made by Setophaga striata (Blackpoll Warbler). Over a 5-y period, we studied differences in preparedness (determined by presence of fat content and arrival time at stopover locations) between hatch-year (HY) and after hatch-year (AHY) Blackpoll Warblers at 3 stopover sites (Hancock and York counties in Maine, and Plymouth County in Massachusetts) covering 2.65° latitude along the Gulf of Maine. Migration timing varied across a latitudinal gradient and between age classes. In September, AHY Blackpoll Warblers were more abundant in the northern and central counties, but HY …

Parasitic Indicators Of Foraging Strategies In Wading Birds, Sarah Gumbleton

HCNSO Student Theses and Dissertations

Feeding ecology and trophic interactions of six species of wading birds were explored through a combined analysis of stable isotope profiles and endoparasite communities. Stable isotopes broadly characterize the feeding preferences and geographic information, while parasite communities reflect long-term trends in feeding ecology. Deceased birds were obtained from four South Florida wildlife rehabilitation organizations. Of the 81 birds dissected, 73 contained parasites. Parasites were predominately found within the gastrointestinal tract. Host and range extensions were noted for several parasite taxa. Bird host species had a significant effect on the parasite community (P=0.001) while wildlife center location and maturity status did …

Follow The Rain? Environmental Drivers Of Tyrannus Migration Across The New World, Maggie P. Macpherson, Alex E. Jahn, Michael T. Murphy, Daniel H. Kim, Victor R. Cueto, Diego T. Tuero, Elliot D. Hill

Biology Faculty Publications and Presentations

Predictable seasonal changes in resources are thought to drive the timing of annual animal migrations; however, we currently understand little about which environmental cues or resources are tracked by different migratory bird species across the planet. Understanding which environmental cues or resources birds track in multiple migratory systems is a prerequisite to developing generalizable conservation plans for migratory birds in a changing global environment. Within the New World, climatic differences experienced by Nearctic–Neotropical migratory (NNM; i.e. breed in North America and spend the nonbreeding period in the Neotropics) and Neotropical austral migratory (NAM; i.e. breed and spend the nonbreeding period …

The ecology of the endemic Usambara Double-collared Sunbird (Cinnyris usambaricus) was investigated in the surrounding areas of and within Mazumbai Forest Reserve in the Lushoto District of Tanzania. As there is little known concerning the ecology of the species, this study sought to illuminate multiple aspects of their behavior and interactions. Over fourteen days (November 2nd-November 21st), the abundance of the species, their nesting behavior, their habitat preferences, their vocalizations, their diet, and their aggressive behaviors were observed and then analyzed. It was determined the species’ activity likely peaks in the early morning, their nesting is similar to other species …

Plasticity Of Foraging Behaviors In Response To Diverse Environmental Conditions, Morgan Gilmour, José Castillo‐Guerrero, Abram Fleishman, Salvador Hernández‐Vázquez, Hillary Young, Scott Shaffer

Faculty Publications, Biological Sciences

Due to rapidly changing global environmental conditions, many animals are now experiencing concurrent changes in both resource availability and the foraging cues associated with finding those resources. By employing flexible, plastic foraging strategies that use different types of environmental foraging cues, animals could adapt to these novel future environments. To evaluate the extent to which such flexibility and plasticity exist, we analyzed a large dataset of a clade (Sulidae; the boobies) of widespread aerial tropical predators that feed in highly variable marine habitats. These surface foragers are typical of many ocean predators that face dynamic and patchy foraging environments and …

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Nesting birds must often cope with harassment from biting insects, but it is difficult to ascertain what effect such pests might have on breeding success and population dynamics. We tested the hypothesis that a black fly (Simulium annulus) that feeds on the blood of nesting Common Loons (Gavia immer) causes nest abandonment in this charismatic diving bird. In addition, we measured effects of fly-induced abandonment on a loon population, and examined potential predictors of fly abundance and nest abandonment. We also tested a second hypothesis, which holds that loon pairs that abandon a nest owing to …

This spring will be remembered for Nebraska’s first unequivocal record of Swainson’s Warbler, unfortunately a “one day wonder”, but well-photographed. Another mega was a Band-tailed Pigeon, Nebraska’s fourth. The old sports saying “wait until next year” was applicable in spades to woodwarblers; last year was noted for its paucity of most species of wood-warblers, but this year, incredible record numbers occurred for several migrant species: Magnolia, Baybreasted, Chestnut-sided, Blackpoll, and Palm. Other amazing numbers were the 598,000 Sandhill Cranes counted at peak migration in the Central Platte Valley and the 598 Great Egrets reported within the amazing 414 reports. Several …

First Record Of Fulvous Whistling-Duck (Dendrocygna Bicolor) For Nebraska, Matthew T. Haugen

Nebraska Bird Review

On the afternoon of 5 June 2018, I was scouting local Salt Valley lakes to get an estimate of goose numbers for annual Canada Goose (Branta canadensis) banding operations. At approximately 2:30 p.m. I was tallying my goose counts in the northwest corner of Wagon Train Wildlife Management Area in Lancaster County, when I noticed four ducks on a nearby vegetated mud flat. After closer examination, I recognized the ducks as Fulvous Whistling-Ducks (Dendrocygna bicolor). I spent a few years working in Louisiana in that state’s waterfowl program, and I am familiar with the species and its identification. I was …
