2023 Coordinated Spring Survey Of Mid-Continent Sandhill Cranes, Terry Liddick
United States Fish and Wildlife: Staff Publications
The aerial transect portion of the coordinated spring survey of mid-continent Sandhill cranes was conducted on March 22, 2023 in Nebraska’s Central Platte and North Platte River valleys (United States). The 2023 photo-corrected aerial estimate is 1,259,000 birds. Outside the traditional aerial transect portion, observers conducted ground surveys during the period March 20–22. From these regions, observers in the Official Survey Area (OSA) of Nebraska, Kansas, Texas, Oklahoma, and Wyoming reported an additional 25,363 cranes. The 2023 total estimate (1,284,500) increased 43.1% from 2022. The current three-year average (2021–2023 with no photo correction in 2021), based on photo corrected estimates …
Raccoons (Procyon Lotor) Show Higher Trypanosoma Cruzi Detection Rates Than Virginia Opossums (Didelphis Virginiana) In South Carolina, Usa, David A. Bernasconi, Madison L. Miller, Jacob E. Hill, Pooja Gupta, Richard Chipman, Amy Gilbert, Olin E. Rhodes Jr., Guha Dharmarajan

USDA Wildlife Services: Staff Publications
Chagas disease, a significant public health concern in the Americas, is caused by a protozoan parasite, Trypanosoma cruzi. The life cycle of T. cruzi involves kissing bugs (Triatoma spp.) functioning as vectors and mammalian species serving as hosts. Raccoons (Procyon lotor) and opossums (Didelphis virginiana) have been identified as important reservoir species in the life cycle of T. cruzi, but prevalence in both species in the southeastern United States is currently understudied. We quantified T. cruzi prevalence in these two key reservoir species across our study area in South Carolina, USA, and …

Vampire Bats: Preparing For Range Expansion Into The U.S., Michael J. Bodenchuk, David L. Bergman
Vampire Bats: Preparing For Range Expansion Into The U.S., Michael J. Bodenchuk, David L. Bergman
USDA Wildlife Services: Staff Publications
The common vampire bat apparently is expanding its range northwards in Mexico and seems poised to enter the southern United States. Climate models predict suitable habitat in the U.S. in south Texas and parts of southern Arizona. While vampire bats’ northward range expansion is not unexpected, the fact that this species brings a strain of rabies that impacts livestock and people warrants a strategic response. Annual economic damages from bats are estimated between $7M and $9M, largely associated with deaths of livestock from rabies. To prepare for the emerging rabies issue, USDA Wildlife Services programs in Texas and Arizona have …
Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull
Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull
United States National Park Service: Publications
Executive Summary
In 2001, the Heartland I&M Network initiated breeding bird surveys on Tallgrass Prairie National Preserve, Kansas, to assess the ecological integrity of the preserve’s habitat. Birds are an important component of ecosystems and can serve as good indicators of habitat change in an ecosystem. In the 17 years of bird surveys at the preserve (2001 to 2018, excluding 2003), there were 2,089 plot visits and 119 different bird species recorded, 96 of which have the potential to breed within the preserve. These 96 species represent approximately 81% of the total species one would reasonably expect to have breeding …
Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan Pfeiffer, Scott C. Barras, Brett Dunlap, Lee A. Humberg
Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan Pfeiffer, Scott C. Barras, Brett Dunlap, Lee A. Humberg
USDA Wildlife Services: Staff Publications
Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human– vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts …

University of Nebraska State Museum: Mammalogy Papers
First paragraph:
On 30 March 2018, the science of mammalogy and the American Society of Mammalogists lost one of the most influential figures of the last half-century. Robert James Baker died quietly at his home in Lubbock, Texas (Fig. 1). He was born on 8 April 1942 to James Simeon Baker and Laura Cooper in Warren, Arkansas. His father was killed during World War II and his mother remarried, resulting in his growing up with six half-siblings. According to Robert’s autobiography in Going afield (330—number refers to specific publication in “Bibliography”), he spent a good deal of his youth with …
Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms
Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms
United States National Park Service: Publications
Abstract
Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …
Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht
Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht
United States National Park Service: Publications
Abstract
Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.
Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …

Hymenolepis Folkertsi N. Sp. (Eucestoda: Hymenolepididae) In The Oldfield Mouse Peromyscus Polionotus (Wagner) (Rodentia: Cricetidae: Neotominae) From The Southeastern Nearctic With Comments On Tapeworm Faunal Diversity Among Deer Mice, Arseny A. Makarikov, Todd N. Nims, Kurt E. Galbreath, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
A previously unrecognized species of hymenolepidid cestode attributable to Hymenolepis is described based on specimens in Peromyscus polionotus, oldfield mouse, from Georgia, United States, near the southeastern coast of continental North America. Specimens of Hymenolepis folkertsi n. sp. differ from those attributed to most other species in the genus by having testes arranged in a triangle and a scolex with a prominent rostrum-like protrusion. The newly recognized species is further distinguished by the relative position and length of the cirrus sac, shape of seminal receptacle, and relative size of external seminal vesicle and seminal receptacle. Hymenolepidid cestodes have sporadically …
Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht
Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht
United States National Park Service: Publications
Executive Summary
Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.
A potential bison …

Nesting Populations Of Double-Crested Cormorants In The United States And Canada, Laura A. Tyson, Jerrold L. Belant, Francesca J. Cuthbert, D.V. (Chip) Weseloh
Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest
Double-crested cormorants (Phalacrocorax auritus) are receiving increasing attention in North America because of depredations at aquaculture facilities and alleged impacts on sport and commercial fisheries. We obtained recent (most since 1994) estimates for the number of nesting double-crested cormorants in the United States and Canada from published references and by conducting telephone interviews with State and Provincial biologists. Using published data, we also determined annual rates of change in the number of cormorants since about 1990. The estimated minimum number of nesting pairs (colonies) of double-crested cormorants was 372,000 (852). Most cormorants nested in the Interior region (68 …
Agelaius Blackbirds And Rice In Uruguay And The Southeastern United States, Ethel N. Rodriguez, Michael L. Avery
Agelaius Blackbirds And Rice In Uruguay And The Southeastern United States, Ethel N. Rodriguez, Michael L. Avery
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Throughout the world, wherever rice is grown, birds that damage the crop are attracted. The situations are particularly interesting in Uruguay and the southeastern United States where different species of blackbird have adapted to rice cultivation. In the two countries, rice production practices differ in several respects such as seeding rate, seedbed preparation, and insect control practices. Furthermore, although they are congeneric, the major rice pest species differ in important ways. For example, in Uruguay, Agelaius ruficapillus usually nests in the rice field, whereas A. phoeniceus, in the U.S., does so only rarely. Agronomic and ornithological aspects of these …
Federal And State Regulations Pertaining To Systematic Collections. I. A Case Of Inadvertent Violation Of Federal Regulations, Jerry R. Choate, Hugh H. Genoways
Federal And State Regulations Pertaining To Systematic Collections. I. A Case Of Inadvertent Violation Of Federal Regulations, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
On 25 April 1975, at the twenty-second annual meeting of the Southwestern Association of Naturalists (SWAN), at the University of Oklahoma Biological Station, President Keith A. Arnold appointed Jerry Choate to investigate current regulations pertaining to collection and transport of scientific specimens in the region of representation (including Mexico) or SWAN. This charge involves both Federal and State laws, several of which are undergoing change and many of which doubtlessly are not familiar to the membership of SWAN. In order that SWAN members might be made aware of these regulations and not unwittingly commit violations, it was decided that SWANEWS …
