How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck Jan 2024

How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck

Undergraduate Research Posters

El-Niño Southern Oscillation (ENSO) causes regional changes in climate and has been found to have varying effects on the survival, fecundity, and recruitment of migratory songbirds. This study seeks to better understand the effect of ENSO on the fecundity of Virginia-breeding Prothonotary warbler (Protonotaria citrea; PROW), a neotropical migratory songbird. PROW breed in the Eastern United States and spend the non-breeding season primarily in Panama and Colombia. Ongoing research in Virginia has found a positive relationship between spring precipitation and predicted number of PROW fledgelings during La Niña, but the opposite during El Niño. To better understand this relationship, we …


Characterization Of Antimicrobial Properties Of Excrement And Functional Microbiome Of Black Vultures (Coragyps Atratus), Bridgette Gray Jul 2023

Characterization Of Antimicrobial Properties Of Excrement And Functional Microbiome Of Black Vultures (Coragyps Atratus), Bridgette Gray

Theses

Black vultures, Coragyps atratus, are obligate scavenging birds that consume and dispose of decaying carcasses and carrion. They fulfill a key ecological niche in the environments in which they live. It has been observed that these vultures sometimes excrete bodily waste onto their legs. This adaptive behavior could help aid them in controlling bacteria and other microbes they encounter while stepping into a carcass to eat. This study directly examined the antimicrobial properties of the excrement of black vultures across various bacterial species utilizing a zone of inhibition test and a nematode species utilizing a survival assay. The black vulture …

Rethinking The Status And Temporal Occurrence Of The American Woodcock In Nebraska Because Of Its Unusual Life History, Joel G. Jorgensen, Stephen J. Brenner Jun 2023

Rethinking The Status And Temporal Occurrence Of The American Woodcock In Nebraska Because Of Its Unusual Life History, Joel G. Jorgensen, Stephen J. Brenner

Nebraska Bird Review

Historical distribution and range expansion -- We reviewed existing information to evaluate conclusions by previous authors (e.g., Sharpe et al. 2001, Silcock and Jorgensen 2023) that woodcock have expanded their range west since settlement of Nebraska by Euro-Americans. We also provide additional context about the species’ distribution over time using regional resources.

Temporal occurrence and abundance -- We used data from woodcock outfitted with satellite transmitters 2021-2022 and compared it with occurrence data from two sources, eBird (eBird.org 2023) from all years through 2022 and the SFRs in the Nebraska Bird Review 1994–2019. We chose not to use SFR data …

Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise Mar 2023

Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise

Georgia Journal of Science

Grassland bird populations are being lost at an alarming rate due to human modifications to grassland ecosystems. Grassland restoration has been shown to mitigate population declines for many species that use these habitats at some point in their annual cycles. We examined capture rates of adult, breeding, and hatch-year birds at a restored grassland site in the piedmont of central Georgia to determine whether colonization, breeding success, hatching success, and recruitment processes were impacting populations of grassland birds. We banded birds approximately twice per month from January 2009 through December 2021 at Panola Mountain State Park. Restoration efforts started in …


Winter Field Report, Dec. 2022 - Feb. 2023, W. Ross Silcock Mar 2023

Winter Field Report, Dec. 2022 - Feb. 2023, W. Ross Silcock

Nebraska Bird Review

Since this is a Winter Seasonal Report, it seems appropriate to lead off with notable reports of occurrences that might be considered unexpected for midwinter, of which there were several. A range of species was involved, suggesting an encompassing cause such as climate change. Of interest were northerly wintering groups of waterfowl including Gadwall, Green-winged Teal, Canvasback, Ringnecked Duck, and Hooded Merganser. Reports of wintering Tundra Swans, Whitewinged Doves, and Lesser Goldfinches continue to increase, and numerous Redwinged Blackbirds in the northeast in midwinter were unexpected. Also quite unexpected were two Sandhill Cranes wintering in the east, the state’s first …


2022-2023 Christmas Bird Counts, Don Paseka Mar 2023

2022-2023 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were run in the 2022-2023 CBC season. Because of weather and rescheduling issues, the Crawford, Harrison, and Harlan County counts were cancelled. Eight of the counts were completed during the first week of the count period and the other eight were scattered throughout the remainder of the count period. An early December cold snap seemed to drive many of the birds south, but the weather on actual count days was fairly benign: mostly dry with an average high of 34˚F and an average low of 19˚F and with three circles reporting light snow. The total number of species …

The Effects Of Chemical Secretions By Millipedes On Anting Behaviour In Birds And Other Animals, Theo Fraser Jan 2023

The Effects Of Chemical Secretions By Millipedes On Anting Behaviour In Birds And Other Animals, Theo Fraser

2023 REYES Proceedings

Birds perform a behavior known as anting in which they actively rub ants in their feathers or allow ants to crawl over their bodies. Several hypotheses have been proposed to explain this behavior, but no one hypothesis can account for all cases of anting that have been observed. Anting behavior has been recorded in species other than birds including primates, and substances other than ants such as millipedes may be used. This paper explores the use of millipedes in anting by birds, capuchin monkeys and lemurs. The three hypotheses supported by these studies include 1) anting serves as food preparation …


Effects Of Climate Change And Landscape-Scale Forest Management On Avian Communities, Abundance, And Nest Success In The Appalachian Mountains, Hannah L. Clipp Jan 2023

Effects Of Climate Change And Landscape-Scale Forest Management On Avian Communities, Abundance, And Nest Success In The Appalachian Mountains, Hannah L. Clipp

Graduate Theses, Dissertations, and Problem Reports

Birds are integral components of ecosystems and account for billions of dollars in tangible benefits to humans. As such, recent continental declines of bird species have ecological and economic consequences, providing the impetus for my dissertation research. I identified knowledge gaps and proposed novel questions about how birds in the Appalachian Mountains are influenced by changing environmental conditions due to climate change and forest management. The Appalachian Mountains encompass an important biogeographical region with high conservation value due to its myriad habitats and corresponding bird species diversity. Thus, there is a critical need to evaluate the effects of shifting climate …

USDA Wildlife Services: Staff Publications

The northern spotted owl (Strix occidentalis caurina; hereinafter NSO) was listed as “threatened” under the Endangered Species Act in 1990 and population declines have continued since that listing. Given the species’ protected status, any proposed activities on Federal lands that might impact NSO require consultation with U.S. Fish and Wildlife Service and part of that consultation often includes surveys to determine presence and occupancy status of the species in the proposed activity area. The objective of this report is to present study-area specific estimates of the probability of detection for NSO pairs from twelve 2-week seasonal survey periods …


Hypotheses Related To Anting By Birds, Helena Flores Jan 2023

Hypotheses Related To Anting By Birds, Helena Flores

2023 REYES Proceedings

“Anting” is a widespread behavior among bird species and mammals. Due to the various characteristics of this behavior, numerous hypotheses have been proposed to explain it. This behavior can be classified as “active”, in which birds take a bill full of ants and rub them into their feathers, or “passive” when birds let ants wander through their plumage. The hypotheses state that anting may be performed as an (1) antiparasitic behavior, for (2) feather grooming, as a way of (3) food preparation or to (4) decrease skin irritation during molt, even as a (5) sensory stimulation tool. This review compiles …

Schramm Park Fall Field Days, Janis Paseka

Nebraska Bird Review

The 2022 NOU Fall Field Days were held at Schramm Park State Recreation Area, south of Gretna in Sarpy County, on September 21-23, with approximately 60 in attendance. The meeting had been scheduled and cancelled twice in the two previous years due to coronavirus concerns. The total species count was 119, including a Sandhill Crane, Prairie Falcon (early for away from breeding area), Winter Wren, and early Snow Bunting. A Limpkin, which had been found in late June at Wehrspann Wetlands mitigation pond in Sarpy County and was still seen through late November in the Wehrspann Lake area, was not …


Remembering Clem Klaphake, Don Paseka Dec 2022

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 …

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

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 …


Summer Field Report, June-July 2022, W. Ross Silcock Sep 2022

Summer Field Report, June-July 2022, W. Ross Silcock

Nebraska Bird Review

As always, the summer season produces surprises, and this year was no exception. Surprises fall into different categories, though: genuine statewide rarities, within-state distributional rarities, and, of course in summer, nesting records at new locations, population notes, late and early dates and high numbers, increased knowledge about subspecies in the state, and miscellaneous things of interest. These categories are covered separately below after some housekeeping comments.

“Genuine statewide rarities” were led by the first state record Limpkin found by Karen Kader and seen by many in Sarpy Co. Potential 2nd or so state records were a Mexican Duck in Scotts …

Spring Field Report, March-May 2022, W. Ross Silcock Jun 2022

Spring Field Report, March-May 2022, W. Ross Silcock

Nebraska Bird Review

This spring there was a large number of interesting reports generated by active field observers, particularly in the west, where our knowledge continues to be broadened in all aspects. The main takeaway this spring was the inordinate plethora of species that matched or exceeded early arrival dates listed in BONO. There were no fewer than 70 species in this category, involving most families and genera, suggesting some overall influence on migration timing. Perhaps exceptions to these early arrivals were some lingering waterfowl and gulls although terns arrived early. Fully 50 of the early arrivers were passerines, notably including nine species …
