Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …

Temperature Affects Nest Box Selection, Nest Success, And Nestling Size In A Southeastern Population Of Eastern Bluebirds, Katie Stumpf

Georgia Journal of Science

Given the critical role of temperature in avian reproduction, rising global temperatures will likely impact reproductive success of many bird populations. We examined the effect of nest box temperature, nest box color, entrance orientation, distance to forest cover, and distance to water on net box selection, nest success, and nestling size in eastern bluebirds (Sialia sialis) in central Georgia. White painted nest boxes had significantly cooler temperatures than control nest boxes (P < 0.05). However, model selection revealed that eastern bluebird females selected control boxes, despite their overall warmer temperatures. Nest success was associated with year, likely because of high nest predation during the warmer 2022 breeding season (P < 0.05). Nest success was also associated with cooler nest boxes, possibly because incubating females spend more time incubating which can reduce predation risks. Larger nestlings fledged from painted nest boxes, nest boxes with cooler temperatures, and nests from 2021, which we attribute to decreased thermoregulatory demands enabling faster nestling growth in cooler boxes and years. These seemingly opposing results suggest there may be an optimal temperature range where nest box temperature maximizes reproductive fitness while minimizing energetic demands on incubating adults. Determining this temperature range can help target management efforts to ensure specific goals are met.

Correcting The Record: Subspecific Identification Of Nebraska’S Lone Common Eider (Somateria Mollissima), Sam Manning, Joel G. Jorgensen, Stephen J. Brenner, W. Ross Silcock

Nebraska Bird Review

In late November or early December 1967, Roger Guenther harvested a Common Eider (Somateria mollissima) on Maloney Canal between Maloney and Sutherland in Lincoln County, Nebraska. The head and a single foot from the carcass were deposited at the University of Nebraska State Museum via the University of Nebraska–Lincoln and the Nebraska Fish and Game Department (now the Game and Parks Commission). Dr. Jean Tate prepared the parts, which were inventoried as specimen #ZM-12341 in the UNSM. Dr. Paul Johnsgard purportedly took this specimen to the Field Museum of Natural History in Chicago for identification purposes, and concluded …

2023 (35th) 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 https://noubirds.org/Birds/ReviewList.aspx. Starting in 2020, the NOURC decided to deal mainly with those species deemed as Accidental on the “Official List of the Birds of Nebraska”. Casual species and out-of- range species are now summarized in the “Seasonal Reports” of the …

Summer Field Report, June–July 2024, W. Ross Silcock

Nebraska Bird Review

This was an intriguing summer in several ways. I am far from being a knowledgeable ecologist, but, like most of us, as a layman I wonder whether and how weather affects birds, and if and how local weather is reflecting the conventional wisdom of climate change. Climate change seems increasingly to be expressed as various extreme or rapidly changing weather events that have differing effects on vegetation and consequently insect and larger prey populations. Every species responds differently it seems, depending on its biological needs, but food supply is the most important issue for birds. It is tempting to assign …

Avian Communities Monitored Along A Successional Chronosequence In Bottomland Hardwood Forests In The Lower Mississippi Alluvial Valley, Eamonn Alasdair Thurmond

Electronic Theses and Dissertations

Bottomland hardwood forests in the Lower Mississippi Alluvial Valley have been extensively reduced due to agriculture conversion and altered hydrology. Remnant forests have undergone further degradation from sources such as a lack of forest management, invasive species, and reduced regeneration of oaks (Quercus spp.). Recent restoration efforts of bottomland hardwood forests have focused on implementing wildlife forestry practices that prioritize restoring wildlife habitat while retaining profitable timber harvests. In this study I surveyed bird communities in bottomland hardwood forests in the Lower Mississippi Alluvial Valley along a successional chronosequence. Birds were sampled using automated recording units over 10 days …

The Early Years Of The Nebraska Ornithologists’ Union: People And Publications, Daniel W. Leger

Nebraska Bird Review

Nebraska once boasted that it had the greatest avian biodiversity of any state. Today, such a claim seems preposterous, but when it was made, back in 1899, it was serious. The antecedents of that claim underlie the objective of this article, namely to describe the early history of the Nebraska Ornithologists’ Union (NOU), its founding members, and its publications, one of which, the Nebraska Bird Review, you are reading today.

To say that many changes have occurred in ornithology and birding since the NOU started in 1899 would be a severe understatement. Most of these changes have …

Spring Field Report, March–May 2024, W. Ross Silcock

Nebraska Bird Review

A major concern this spring was the widely lamented shortfall in numbers of migrant warblers and the shortened duration of the migration, with most sightings relatively early. Numbers of migrant warblers east of the 100th meridian were investigated by Joel Jorgensen and Stephen Brenner and the scarcity was indeed found to be supported by eBird data; see the “News and Updates” section in Birds of Nebraska-Online (BONO). At Oliver Reservoir in the Panhandle, however, Steven Mlodinow found that migration was at least normal for a range of common migrants, with some migrants above the levels of the last four years. …

Winter Field Report, December 2023–February 2024, W. Ross Silcock

Nebraska Bird Review

As was the case for winter 2022–2023, the big general story was the large number of reports of tardy fall migrants and unexpectedly northerly occurrences in midwinter, an apparent residue of relatively mild early winter temperatures. These reports involved at least 50 species, many of them waterbirds and native sparrows, but including several other passerines as well. Notable were about 12 waterfowl species, five grebe species, an interesting late Dec peak in each of the last three years of Sandhill Cranes, record late Whooping Cranes, a 4th winter record of Dunlin, high numbers of Double-crested Cormorants, a wintering Rock Wren, …

2023–2024 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

With the resurrection of the Kearney count, twenty CBCs [Christmas Bird Counts] were run in the 2023–2024 season. This is four more than last year and one more than the previous high number of nineteen from 2021. Although the Crawford, Harrison, and Scottsbluff counts were postponed because of snow, the weather on count days was mild with an average high of 43°F and an average low of 27°F, resulting in mostly open water. Rain and mud eliminated access to several normally productive areas of the Harlan County count which still produced the highest number of species (94). Lake McConaughy produced …

Nocturnal Behavior Of Communally Roosting American Crows (Corvus Brachyrhynchos), Caitlin M. Mrowiec

Masters Theses

During the winter months in Charleston, Illinois, thousands of American crows (Corvus brachyrhynchos) gather together each night to roost. While aspects of this impressive sight have been studied elsewhere, there is very limited information on how crows behave at night. Additionally, the mechanics and origins of communal roosting are not especially well understood, and the behaviors involved are not always consistently described. This study sought to provide a more complete assessment of crow communal roosting after sunset. I collected data between 2018 and 2020 by locating communal roosts and conducting continuous observations for 4 hours after sunset, with additional checks …

Rapid Point-Of-Care Testing For Detection Of Antibodies To Toxoplasma Gondii In Black Vultures And Ring-Billed Gulls From Pennsylvania, Alexa Rosypal Von Dohlen, Sydney Randall, Jordyan Grays, Mark A. Dugo, Brian J. Hunt, Justin Brown, Kyle Van Why, Sawsan Ammar, Richard Gerhold

United States Department of Agriculture Wildlife Services: Staff Publications

Toxoplasma gondii is a zoonotic protozoan parasite that infects most warm-blooded animals, including birds. Scavenging birds are epidemiologically important hosts because they can serve as indicators of environmental T. gondii levels. A rapid point-of-care (POC) test that detects antibodies to T. gondii in humans is commercially available. In this research, we assessed the ability of the human POC test to detect anti–T. gondii antibodies in 106 black vultures (Coragyps atratus) and 23 ring-billed gulls (Larus delawarensis) from Pennsylvania, USA. Serum samples were tested with the POC test and compared to the modified …

Investigating Birds As Dispersal Vectors Of Litylenchus Crenatae Subsp. Mccannii (Anguinidae), The Nematode Associated With Beech Leaf Disease, Spencer Rock Parkinson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Beech leaf disease (BLD) is an emerging forest pathogen primarily affecting American beech (Fagus grandifolia, Ehrh.) in North America and has been attributed to tree mortality of sapling sized trees within five to seven years of infection. Symptoms typically occur in regenerating American beech thickets sprouting from roots of trees killed by beech bark disease. Scientists first observed BLD in Ohio in 2012 and currently has spread to 15 states in the USA and one Canadian province. The nematode Litylenchus crenatae subsp. mccannii (Lcm) is highly associated with BLD symptoms, interveinal chlorosis and defoliation of leaves, and is currently …

Divergent Response To Anthropogenic Change Within The Songbird Taxon: Insights From The Range Expansion Of The Northern Cardinal And Mitigation Mechanisms For Migratory Bird-Building Collisions, Jenna Brewer

Dissertations, Master's Theses and Master's Reports

Anthropogenic activities have impacted ecosystems across the globe. However, wildlife species have exhibited heterogenous responses to these novel changes, with some species experiencing population growth, and others succumbing to population decline. I studied examples of both within the songbird taxon, focusing on drivers of range expansion in the Northern Cardinal and acoustic mitigation mechanisms for migratory bird-building collisions, a source of decline for many songbird species. I found that the Northern Cardinal’s range was primarily a function of climatic stress, which was supported by the modulation of the molt process across latitudes. Specifically, Northern Cardinals exhibited faster feather growth rates …

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 …

Fall Field Report, August–November 2023, W. Ross Silcock

Nebraska Bird Review

As in the last few fall seasons, late departure dates continue to increase in number. This is often attributed to a warming climate but may also result from increased observer activity and usage of eBird. Late dates are probably the most important aspect of this report, most prominent the record late fall dates for Ruby-throated Hummingbird, Sanderling, Bank Swallow, and Cassin’s Sparrow. Although these species are taxonomically diverse, there were species group concentrations of late dates, notably among shorebirds. Examples were Marbled Godwit for which the four latest reports this fall were four of the latest six fall dates on …

Yellow-Throated Warbler In Scotts Bluff County, Nebraska, Mark A. Brogie, Bill F. Huser, Jerry Probst

Nebraska Bird Review

Yellow-throated Warbler (Setophaga dominica) is a rare to uncommon migrant in eastern and central Nebraska. It is possibly a regular breeder locally at sites containing sycamores in several southeastern Nebraska counties bordering the Missouri River. There are few Nebraska reports after July, with more reports November–January than August–October. This species has three previous documented Nebraska Panhandle records, all from May.

1. One photographed 26 May 2009, at Crescent Lake NWR, Garden Co.

2. One seen and “well described” 06 May 1931, at Antioch, Sheridan Co.
