Human–Wildlife Interactions
Wild pigs (Sus scrofa) are abundant and widely distributed in the United States. They damage crops and pastures, predate livestock and sensitive species, impact ecosystem functions, and damage personal property. To address these issues, some states in the United States are seeking complete elimination. A frequently asked question by stakeholders is: “What portion of the population needs to be removed annually to reach elimination?” The number 70% is widely touted as the answer. There is little scientific evidence to support that this percent annual removal would be needed to achieve elimination, yet 70% has now become a standard …

Human–Wildlife Interactions
The small Indian mongoose (Urva auropunctata [syn. Herpestes auropunctatus]; mongoose) is a highly invasive species in its introduced range that negatively impacts ecosystems. Mongooses depredate native species, serve as a vector of disease posing a risk to human health, and cause sanitation issues in food processing facilities and public areas. Introduced for biocontrol in the late 1800s in Hawaiʻi and the Caribbean, mongooses currently have well-established populations across multiple islands in both island archipelagos and have invaded numerous other locations throughout the world. The concern of accidental introduction to mongoose-free islands, the difficulty in species detection, and the …

European Starling Use Of Nest Boxes Relative To Human Disturbance, Bradley F. Blackwell, Bruce N. Buckingham, Morgan B. Pfeiffer
Human–Wildlife Interactions
European starling (Sturnus vulgaris; starling) nesting poses debris hazards within airport hangars and to engine and flight surfaces of moored aircraft. We questioned whether consistent removal of nest material would negatively affect use of a nest site, measured by a reduction in material accumulation. We conducted our study on a 2,200-ha site in Erie County, Ohio, USA (41° 22’ N, 82° 41’ W), from April 15 through June 2, 2020. We used 120 wooden nest boxes on utility poles, protected by an aluminum predator guard below the box. Our treatments included (1) twice weekly, repeated nest material removal …

European Starlings Fly Before They Fledge, Jeremiah L. Psiropoulos, Lisa A. Selner
Human–Wildlife Interactions
Aircraft bird strikes are increasing globally. Bird strikes constitute a major human health and safety risk and result in millions of dollars in economic impacts. Invasive avian species, such as the European starling (Sturnus vulgaris; starlings), have been implicated in bird strikes in North America. Because this species is highly adaptive and has been successful at establishing in new areas, such as airports, it is essential that managers better understand the potential risks and how to mitigate them. Herein we present a case study regarding a novel observation of unique starling nesting behavior that may pose a risk …

Regulation Of Tree Squirrel Populations With Immunocontraception: A Fox Squirrel Example, Sara K. Krause, Douglas A. Kelt, Dirk H. Van Vuren, James P. Gionfriddo
Human–Wildlife Interactions
Tree squirrels (Sciurus spp.) are highly successful immigrants to urban and suburban areas in North America and Europe, causing both economic and ecological damage. Control of such invasive populations is challenging but of increasing importance to local managers. We studied an invasive population of fox squirrels (S. niger) and applied an immunocontraceptive vaccine in an experimental study of demographic control. Here we integrate our data into a simple stage-structured population model to simulate population reduction under 2 treatment levels (60 and 80% of females, respectively) for vaccines lasting from 1 to 5 years. Contraception can be an effective …
Efficacy Of Aerial Broadcast Baiting In Reducing Brown Treesnake Numbers, Larry Clark, Peter J. Savarie
Efficacy Of Aerial Broadcast Baiting In Reducing Brown Treesnake Numbers, Larry Clark, Peter J. Savarie
Human–Wildlife Interactions
The brown treesnake (Boiga irregularis) is an invasive predator that was introduced on Guam as a stowaway in cargo after World War II. Since then, the population has exploded, attaining 50 to 100 snakes per ha in some areas. The snake has caused the extirpation of ten of the 12 native forest bird species on Guam. The U.S. Department of Agriculture, Wildlife Services, has a program to deter the spread of snakes from Guam to other islands. Hand capture from fences, trapping, toxic bait stations, and canine inspection of outbound cargo methods are used in the control program …

The Effect Of European Starlings And Ambient Air Temperature On Salmonella Enterica Contamination Within Cattle Feed Bunks, James C. Carlson, Jeremy W. Ellis, Shelagh K. Tupper, Alan B. Franklin, George M. Linz
Human–Wildlife Interactions
European starlings (Sturnus vulgaris) are a known risk factor for the occurrence of microorganisms that are pathogenic to cattle and humans in concentrated animal feeding operations (CAFOs). Starling use of CAFOs is known to vary in response to weather; starling control operations on CAFOs often are timed to coincide with favorable environmental conditions to maximize take. The totality of this information suggests that disease risks in CAFOs associated with starlings may be influenced by environmental factors, such as temperature. In this study, we assessed the risk of Salmonella enterica contamination of cattle feed by modeling the interaction between …

Brown Treesnakes: A Potential Invasive Species For The United States, Samantha Sue Kahl, Scott E. Henke, Marc A. Hall, David K. Britton
Human–Wildlife Interactions
Brown treesnakes (ˆ) are mildly venomous, exotic snakes that have the potential to become an invasive species in North America, Hawaii, and the Commonwealth of the Northern Mariana Islands. The snake is native to northern and eastern Australia, New Guinea, and other islands of northern and western Melanesia. The snakes were first found outside their native range on Guam in 1953. The exact date they reached the island is uncertain, but they are believed to have arrived on military cargo transport vessels some time during or just after World War II. During the years that followed, the population of brown …

Examining A Potential Brown Treesnake Transport Pathway: Shipments From Guam, Samantha Sue Kahl, Scott E. Henke, Marc A. Hall, Andrea R. Litt, Gad Perry, David K. Britton
Human–Wildlife Interactions
Shipments of cargo and household goods have been identified as pathways for brown treesnake (Boiga irregularis) transport from Guam to other locations. We analyzed data regarding shipments of military household goods leaving Guam during 2006 to 2009 to identify the potential for human transport of brown treesnakes to the United States by determining when shipments most commonly occur and identifying primary receiving areas. We found that the number of shipments was highest during the months of May and June and that California receives more shipments (23% of total shipments) than any other location. Approximately 98% of shipments originated …

Rock Pigeon Use Of Livestock Facilities In Northern Colorado: Implications For Improving Farm Bio-Security, James C. Carlson, Larry Clark, Michael F. Antolin, Mo D. Salman
Human–Wildlife Interactions
Rock pigeons (Columba livia) have been implicated in the spread of pathogens within commercial livestock facilities. Currently, there is no data characterizing pigeon habitat use and movement patterns within and among commercial livestock facilities. To better understand the capacity for pigeons to spread pathogens, we used radio-telemetry techniques to estimate the home-range, travel distance, activity, and habitat use of pigeons roosting on and off dairies and feedlots in western Weld County, Colorado. Our observations suggest that pigeons roosting on (resident) and off (nonresident) livestock facilities use habitat differently. Nonresident pigeons used larger home-range areas than did resident pigeons. …

An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer
Human–Wildlife Interactions
Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the …

Adaptive And Economic Management Methods For Feral Hog Control In Florida, Richard M. Engeman, Bernice U. Constantin, Stephanie A. Shwiff, Henry T. Smith, John Woolard, John Allen, John Dunlap
Human–Wildlife Interactions
Feral hogs (Sus scrofa) negatively impact the environment in most places around the world where they have been introduced into the wild. In many places, hog removal is essential to protect special habitats, in particular, wetlands. This paper describes techniques developed for use in adaptive management approaches to enhance hog removal efforts in Florida, as well as methods to evaluate the economic impacts from hog management. A valuable adaptive management tool that can be an easily applied index to monitor feral hog activity is track plots. This method has been effective for monitoring hog distribution and relative abundance, …

Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins
Human–Wildlife Interactions
Texas harbors the largest population of feral hogs (Sus scrofa) in the United States, with populations estimated at >2 million. Depending on one’s perspective, feral hogs are either a pariah (from the farmer’s standpoint) or a popular sporting animal (from a hunter’s standpoint). As feral hogs increase in range and density, conflicts among stakeholders are sure to increase. Texas Cooperative Extension (TCE) initiated educational programs in 1991 to address concerns regarding the presence and management of feral hogs. Since that time, we have developed various workshops, symposia, and educational materials (e.g., print, videotape, and website) as means of …
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Human–Wildlife Interactions
Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most vulnerable, and control methods employed. Bird problems varied by island, but cardinals ( …
