Remembering Clem Klaphake, Don Paseka

Nebraska Bird Review

Clement (Clem) Klaphake passed away on December 30, 2022, from complications of Parkinson’s disease, which he struggled with for several years. He was born in Melrose, Minnesota, in 1943 and grew up working on his parents’ dairy farm, which included the usual menagerie of other farm animals typical of that time. Perhaps it was the routine of milking twice a day, seven days a week, or the impressive scar on his leg from a boar tusk, but Clem was destined to leave the farm and become a life-long educator. ... After getting his degree in 1971, Clem was hired to …

Seabirds As Proxies For Past El Niño Events In Coastal Peru: An Archaeo-Ornithological Approach, Heather A. Landazuri

Electronic Theses and Dissertations

This thesis sets an initial foundation for an archaeo-ornithological approach to understanding past El Niño events on the coast of Peru and the use of avifaunal remains as proxies for ecological conditions. Although faunal remains from archaeological sites do not provide exact representations of past environmental conditions, and bird remains can be especially challenging environmental indicators, their presence does reflect decisions made by human occupants in response to environment. Additionally, zooarchaeological data offer a reflection of past animal availability and use, much of which is at least in part determined by environmental conditions. Here I examine the extent to which …

The Distribution And Reproductive Success Of The Western Snowy Plover Along The Oregon Coast - 2022, David J. Lauten, Kathleen A. Castelein, Daniel Farrar, Mary Lee, Eleanor P. Gaines

Institute for Natural Resources Publications

We monitored the distribution, abundance and productivity of the federally threatened Western Snowy Plover (Charadrius nivosus nivosus) along the central and south coast of Oregon from 1 April – 15 September 2022. We surveyed and monitored plover activity in a project area that included, from north to south, Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Snowy Plover Management Area, New River Habitat Restoration Area (HRA) and adjacent lands, and Floras Lake. Our objectives for the project area in 2022 were to: 1) estimate the size of the adult Snowy …

Temperature Affects Nest Box Occupancy, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek

Biology Theses

Given the critical role that temperature plays in avian reproductive biology, rising temperatures as a result of global climate change will likely impact reproductive success of many bird populations. Secondary cavity nesting birds, many of which rely on artificial nest boxes to maintain population levels, may be particularly at risk because increased temperatures inside nest boxes can determine whether nest boxes are selected, reduce nest success, and/or negatively affect the growth and survival of offspring. We examined the effect of nest box color on nest box temperature and the influence of nest box temperature, nest box color, entrance orientation, and …

Fall Field Report, August-November 2022, W. Ross Silcock

Nebraska Bird Review

All in all, this was a fairly uneventful fall season, although even uneventful seasons have their share of oddities and variations from the norm. A noteworthy event was a fire that took out much of the brushy habitat in Carter Canyon, Scotts Bluff Co (see photo on following page). It will be interesting to read upcoming spring reports to see what effect the fire might have had on numbers of birds that frequent brushy areas, like towhees and buntings. Optimistically, fires have attracted rare woodpeckers, with first to arrive Black-backed, which would be a first documented Nebraska record, and typically …

The Effect Of Infection Risk On Female Blood Transcriptomics, Brenna M. G. Gormally, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Defenses against pathogens can take on many forms. For instance, behavioral avoidance of diseased conspecifics is widely documented. Interactions with these infectious conspecifics can also, however, lead to physiological changes in uninfected animals, an effect that is much less well understood. These changes in behavior and physiology are particularly important to study in a reproductive context, where they can impact reproductive decisions and offspring quality. Here, we studied how an acute (3 h) exposure to an immune-challenged male affected female blood transcriptomics and behavior. We predicted that females paired with immune-challenged males would reduce eating and drinking behaviors (as avoidance …

The Nesting Behavior Of Russet-Backed Oropendola On Sumak Allpa, Ecuador: An Analysis Of Nest Construction And Interactions With Competing Species, Claire Molina

Independent Study Project (ISP) Collection

Nests are the literal place of birth of bird species; they are incredibly important in the survival and reproduction of populations. Therefore, nesting behavior is a gateway into the lives and success of the animals. With the degradation of natural landscapes due to human activity, there is more of a need to monitor these nests to ensure healthy inhabitants. The Russet-backed Oropendola (Psarocolius angustifrons) creates unique, pendulous nests that are subject to piracy, parasitism, and predation; as well as weather phenomenon’s such as wind and rainstorms. This study describes the nest construction behavior, nest materials and nest architecture by collecting …

Hummingbird Diversity, Abundance, And Feeding Interactions Across Three Floral Communities On Mount Totumas, Chiriquí, Panamá, Zachary Ginn

Independent Study Project (ISP) Collection

(Trochilidae) are a large Neotropical bird family of nectar-feeders that have evolved as pollinators of many Neotropical plants. Interactions between hummingbirds and plants form mutualistic networks that may change in structure over environmental and anthropogenic gradients. While the unique dynamics of hummingbird diversity and floral interactions have been studied throughout the Neotropics, differing drivers between locations emphasizes the need for further local research. This deficit is especially crucial in biodiverse and understudied locations like the Western Highlands of Panamá. In this study, I investigated how hummingbird diversity, abundance, and floral interactions differed between Cloud Forest, Garden, and Oak Forest on …

The Role Of Frugivorous Birds As Seed Dispersers: Feeding Selection And Preference Of Madagascar’S Avian Frugivores In Analamazaotra Forest, Thaddeus Bashaw

Independent Study Project (ISP) Collection

Madagascar is a country rich in floral and faunal diversity. However, anthropogenic habitat destruction and climate change increasingly threaten its biodiversity. Endozoochorous plants that dependent on frugivory for seed dispersal are under threat due to increasing rates of localized extinctions of frugivorous lemurs, the primary seed dispersers of the island. While lemurs are the islands most abundant frugivores, other frugivorous vertebrates like birds and bats likely play a significant role in seed dispersal, although this role is still poorly understood. This study, conducted in Analamazaotra forest, compares the rates of visitation and consumption of six endemic fruiting tree species by …

The most represented family is that of the Anatidae with twelve species while the family with the highest number is that of the Phenicopteridae represented only by one species, …

Winter Diet Of Montezuma Quail In Arizona And New Mexico, Oscar E. López-Bujanda, Alberto Macías-Duarte, Reyna A. Castillo-Gámez, Angel B. Montoya

National Quail Symposium Proceedings

Investigating the diet composition of Montezuma quail (Cyrtonyx montezumae) is fundamental for unveiling how food resources limit the species’ population size and may provide relevant tools for their harvest and habitat management. The objective of this research was to determine the composition and geographic variation of the winter diet of the Montezuma quail in Arizona and New Mexico, USA, from quail crops harvested during the hunting seasons of 2008–2017. In addition, we used beta regression analyses to determine the effect of environmental factors and ecological variables (annual mean precipitation, annual mean temperature, landscape diversity, diet diversity, time of …

Composition Of The Montezuma Quail’S Diet In Arizona, New Mexico, And Texas, Ana G. Paredes-Acuña, Alberto Macías-Duarte, Reyna A. Castillo-Gámez, Angel B. Montoya, James H. Weaver

National Quail Symposium Proceedings

The Montezuma quail (Cyrtonyx montezumae) is a popular game bird and an indicator species of oak-pine savannas in the northern part of its range. In Arizona and New Mexico, USA, robust populations allow for a hunting season from mid-November through mid-February. However, there is no open hunting season for this quail in Texas, USA. Data on the Montezuma quail’s diet can provide new information and improve management of the species. Our objective was to analyze the diet composition of the Montezuma quail in Arizona, New Mexico, and Texas. Specimens were collected by hunters in Arizona and New Mexico …

Population Density Estimates Of The Montezuma Quail (Cyrtonyx Montezumae) In West Texas, Alberto Macías-Duarte, Angel B. Montoya, James H. Weaver

National Quail Symposium Proceedings

In Texas, USA, populations of Montezuma quail (Cyrtonyx montezumae) can be found scattered across mountain ranges in the Trans-Pecos region, including the Davis and Guadalupe, and farther east into the Edwards Plateau region. Abundance and distribution information to assist land managers in the enhancement of Montezuma quail populations is scarce due to the species’ secretive behavior and unknown abundance. We aimed to provide population density indices to fill this information gap by using a search path technique. We searched for quail in the winter of 2018–2019 in West Texas at 6 study sites: 5 private ranches and Elephant …
