Avian Influenza A Virus Associations In Wild, Terrestrial Mammals: A Review Of Potential Synanthropic Vectors To Poultry Facilities, J. Jeffrey Root, Susan A. Shriner
United States Department of Agriculture Wildlife Services: Staff Publications
The potential role of wild mammals in the epidemiology of influenza A viruses (IAVs) at the farm-side level has gained increasing consideration over the past two decades. In some instances, select mammals may be more likely to visit riparian areas (both close and distant to farms) as well as poultry farms, as compared to traditional reservoir hosts, such as waterfowl. Of significance, many mammalian species can successfully replicate and shed multiple avian IAVs to high titers without prior virus adaptation and often can shed virus in greater quantities than synanthropic avian species. Within this review, we summarize and discuss the …

Motion-activated wildlife cameras (or “camera traps”) are frequently used to remotely and noninvasively observe animals. The vast number of images collected from camera trap projects has prompted some biologists to employ machine learning algorithms to automatically recognize species in these images, or at least filter-out images that do not contain animals. These approaches are often limited by model transferability, as a model trained to recognize species from one location might not work as well for the same species in different locations. Furthermore, these methods often require advanced computational skills, making them inaccessible to many biologists. We used 3 million camera …

Wild aquatic birds maintain a large, genetically diverse pool of influenza A viruses (IAVs), which can be transmitted to lower mammals and, ultimately, humans. Through phenotypic analyses of viral replication efficiency, only a small set of avian IAVs were found to replicate well in epithelial cells of the swine upper respiratory tract, and these viruses were shown to infect and cause virus shedding in pigs. Such a phenotypic trait of the viral replication efficiency appears to emerge randomly and is distributed among IAVs across multiple avian species and geographic and temporal orders. It is not determined by receptor binding preference …

Using Bioenergetics And Radar-Derived Bird Abundance To Assess The Impact Of A Blackbird Roost On Seasonal Sunflower Damage, Bonnie A. Clark, Page E. Klug, Phillip M. Stepanian, Jeffrey F. Kelly
United States Department of Agriculture Wildlife Services: Staff Publications
Methods aimed at reducing avian damage to agricultural crops are routinely implemented in situations where efficacy can be assessed by quantifying blackbird (Icteridae) abundance relative to environmental variables and extrapolating to ensuing crop damage. Concomitantly, Weather Surveillance Radar (WSR) data may have potential to enhance crop damage mitigation through improved monitoring of nuisance wildlife populations. We used WSR to derive daily abundance estimates of blackbirds at a fall roost in North Dakota, USA from 2012 to 2019. We integrated these estimates with previously developed bioenergeticseconomic models to estimate local sunflower (Helianthus annuus) damage. The greatest losses usually occurred during …

Historic And Contemporary Use Of Catfish Aquaculture By Piscivorous Birds In The Mississippi Delta, Paul C. Burr, Jimmy L. Avery, Garrett M. Street, Bronson K. Strickland, Brian S. Dorr
United States Department of Agriculture Wildlife Services: Staff Publications
Piscivorous birds are the primary source of catfish (Ictalurus spp.) depredation at aquaculture facilities in northwestern Mississippi. Of particular concern is the Double-crested Cormorant (Phalacrocorax auritus), which can cost aquaculture producers millions of dollars annually through the depredation of cultured fish. Historical research conducted in the early 2000s estimated cormorant use of aquaculture ponds in the region, but aquaculture area has decreased by more than 70% since those estimates were made. With less aquaculture available, we predicted cormorant densities on aquaculture would be greater today than historically. Applying a similar methodology as in historical studies, we used …
Invasive Species Control And Resolution Of Wildlife Damage Conflicts: A Framework For Chemical And Genetically Based Management Methods, Larry Clark, John Eisemann, John Godwin, Katherine Horak, Kevin Oh, Jeanette R. O'Hare, Antoinette J. Piaggio, Kim M. Pepin, Emily W. Ruell
United States Department of Agriculture Wildlife Services: Staff Publications
Vertebrate wildlife damage management relates to developing and employing methods to mitigate against damage caused by wildlife in the areas of food production, property damage, and animal or human health and safety. Of the many management tools available, chemical methods (e.g., toxicants) draw the most attention owing to issues related to environmental burden, species specificity, and humaneness. Research and development focusing on RNA interference and gene drives may be able to address the technical aspects of performance goals. However, there remain many questions about regulation, environmental risk, and societal acceptance for these emerging biological technologies. Here we focus on the …

Common pest birds in the United States include the non-native European starling (Sturnus vulgaris), house sparrow (Passer domesticus), and the pigeon (Columba livia domestica), as well as native birds including Canada geese (Branta canadensis) and gull species (Laridae). Large concentrations of pest birds can create human health hazards and monetary losses due to consumption of crops, depredation, and fecal contamination and accumulation. Fecal contamination hazards include the potential spread of zoonotic diseases including antimicrobial-resistant zoonoses and human injury due to the accumulation of fecal material on walking surfaces. Additionally, fecal accumulation causes …

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 …

There is a strong correlation between bird mass and the likelihood of aircraft damage during a bird–aircraft collision. Thus, the U.S. Federal Aviation Administration (FAA) has established airworthiness standards related to bird mass for engines, airframes, and windshields. Most standards use large (1.8 kg) and medium (1.1 kg) birds as benchmarks (the empennage and certain large turbofan engines use a 3.6-kg bird). There are 20 large (≥1.8 kg) and 16 medium (1.1–1.7 kg) bird species in North America with ≥20 strikes reported for civil aircraft (FAA National Wildlife Strike Database), 1990 to 2018. I analyzed the population changes of these …

Platynosomum fastosum is a cat liver fluke causing hepatobiliary diseases in cats. To evaluate the criterior to support the suspicion index for early disease detection during subclinical infection, the biochemical parameters composed of liver, pancreatic enzymes, tumor markers were evaluated in 14 P. fastosum naturally-infected cats. As a result, alanine transaminase (ALT) and gamma glutamyl transferase (GGT) were found elevated in 57.8% (8/14) of infected cats. For the diagnostic imaging, bile sediments were present in 85.7% (12/14) of infected cats in their gallbladders. Since the number of bile-derived P. fastosum eggs were significantly higher than that from fecal samples (p=0.001), …

Subclinical mastitis (SCM) is a major and silent problem of public health concern. It causes higher economic losses with no initial visible changes in the appearance of milk or udder. Subclinically affected animals always remain a continuous source of infection. Most of the clinical mastitis (CM) cases start as subclinical; hence controlling SCM is the best way to reduce the incidence of diseases. A crosssectional study was carried out during 2018?19 in six districts from different agroclimatic zones of Punjab, India to describe awareness about various technologies and its adoption to diagnose SCM. The multistage random technique was used to …
