One Step Closer To A Better Starling Trap, James R. Thiele
One Step Closer To A Better Starling Trap, James R. Thiele
USDA Wildlife Services: Staff Publications
European starlings (Sturnus vulgaris) are an invasive species in the United States that damage agriculture, personal property, and threaten human health and safety. The U.S. Department of Agriculture Wildlife Services provides technical support to mitigate damage by controlling starling populations at concentrated animal feeding operations, landfills, utilities, and urban areas. Wildlife Services uses DRC-1339, a registered toxicant, to reduce starling populations. Trapping can also be an effective tool but requires more time at a higher cost than DRC-1339. Trapping starlings, however, may be needed to provide a viable alternative to mitigate damage in areas where toxicant use may …

The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the movement data …
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
School of Natural Resources: Faculty Publications
We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (probability of capture in a single tunnel system using 3 traps; 63%) than nonirrigated alfalfa fields (26%). We did not determine whether this variance was due to behavioral differences between Geomys bursarius and Geomys lutescens. We found that trapping pocket …
Rural Inhabitant Perceptions Of Sandhill Cranes In Wintering Areas Of Northern Mexico, Ingrid Barcelo, Juan Carlos Guzmán-Aranda, Felipe Chávez-Ramírez, Larkin A. Powell
Rural Inhabitant Perceptions Of Sandhill Cranes In Wintering Areas Of Northern Mexico, Ingrid Barcelo, Juan Carlos Guzmán-Aranda, Felipe Chávez-Ramírez, Larkin A. Powell
School of Natural Resources: Faculty Publications
Trends in the mid-continent population of sandhill cranes (Grus canadensis) indicate that the species is increasing. A large proportion of this population winters in northern Mexico where possible conflicts between local inhabitants and cranes can occur. We conducted interviews of 40 rural inhabitants living near wetlands used by cranes in three Mexican states. All interviewees had knowledge of cranes and were capable of describing them. The arrival of cranes affected 43% of interviewees. The negative effects were mainly destroyed crops with a subsequent diminished production. Seventy percent of those affected implemented scare tactics to deter the birds, while others (15%) …
Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, Crissa K. Cooey, Jesse A. Fallon, Michael L. Avery, James T. Anderson, Elizabeth A. Falkenstein, Hillar Klandorf
Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, Crissa K. Cooey, Jesse A. Fallon, Michael L. Avery, James T. Anderson, Elizabeth A. Falkenstein, Hillar Klandorf
USDA Wildlife Services: Staff Publications
There is no reliable method for determining age for most species of long-lived birds. Recent success using the skin chemical pentosidine as a biomarker has shown promise as an aging tool for birds. Pentosidine levels have been determined only from the breast tissue of carcasses, and we sought to refine the procedure with respect to biopsy size and location for safe and effective use on living birds. We compared pentosidine concentrations in 4 skin-size samples (4, 6, 8, and 20-mm diameter biopsies) from the breast of black vulture (Coragyps atratus) carcasses. We also compared pentosidine levels from breast …
Evaluation Of Rhodamine B As A Biomarker For Raccoons, Tricia L. Fry, Todd C. Atwood, Mike R. Dunbar
Evaluation Of Rhodamine B As A Biomarker For Raccoons, Tricia L. Fry, Todd C. Atwood, Mike R. Dunbar
USDA Wildlife Services: Staff Publications
The USDA/APHIS/Wildlife Services (WS) oral rabies vaccination program uses tetracycline, a broad-spectrum antibiotic and relatively reliable biomarker, to quantify vaccinebait uptake by raccoons (Procyon lotor). However, obtaining samples (e.g., bone or teeth) to assess tetracycline uptake is highly invasive, and sample preparation can be expensive. By contrast, rhodamine B, a commercially available dye, is absorbed systemically in growing tissues, including hair and whiskers, and can be observed under ultraviolet (UV) light as fluorescent orange bands. Our goal was to evaluate whether rhodamine B can be used as a biomarker to monitor bait uptake by raccoons. We began by …
Forensic Bird-Strike Identification Techniques Used In An Accident Investigation At Wiley Post Airport, Oklahoma, 2008, Carla J. Dove, Nor Faridah Dahlan, Marcy Heacker
Forensic Bird-Strike Identification Techniques Used In An Accident Investigation At Wiley Post Airport, Oklahoma, 2008, Carla J. Dove, Nor Faridah Dahlan, Marcy Heacker
Human–Wildlife Interactions
On March 4, 2008, a Cessna Citation 1 (Model 500) crashed in a wooded area near Wiley Post Airport, Oklahoma, killing all 5 people on board. This paper describes the detailed forensic methods and expertise used by the Smithsonian Institution’s Feather Identification Lab to identify the bird that caused this bird-strike incident. We used standard methods of whole-feather analysis, microscopic examination, and DNA barcoding in this case to identify American white pelican (Pelecanus erythrorhynchos) as the bird species involved in this fatal crash. We also report the importance of proper field investigation and evidence collection for accurate results, …
Using Wedelia As Ground Cover On Tropical Airports To Reduce Bird Activity, Michael A. Linnell, Michael R. Conover, Tim J. Ohashi
Using Wedelia As Ground Cover On Tropical Airports To Reduce Bird Activity, Michael A. Linnell, Michael R. Conover, Tim J. Ohashi
Human–Wildlife Interactions
aircraft collisions (i.e., bird strikes) are a major problem at airports worldwide, often because birds are attracted to airfields to feed on seeds, insects, or rodents that abound in the grassy areas near runways and taxiways. We compared an alternative ground cover, wedelia (Wedelia trilobata), to existing vegetation (control plots) on the airfield at Lihue Airport, Kauai, Hawaii, to determine if bird populations on the airport could be reduced by eliminating their forage base. We studied wedalia because it is a low-growing plant that did not need mowing, was easily established in plots, and out-competed other plants, resulting …
Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender
Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender
Human–Wildlife Interactions
Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability of RMNP’s bear population or could increase the potential for human–bear conflict. Therefore, we investigated contemporary survival and productivity parameters for RMNP’s black bear population from 2003 to 2006 and compared these values to historic levels (1984–1991) and population means throughout the western United States to clarify the current status of RMNP’s bear population. The contemporary black bear population showed signs of …
Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson
Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson
Human–Wildlife Interactions
We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations using VHF telemetry and indirect band recovery at locations north of South Dakota. Telemetry of radio-collared female geese during the breeding season indicated that 56% of nonbreeders, 81% of unsuccessful breeders, and 19% of successful female breeders embarked on a molt migration. Five of 34 geese that underwent molt migrations moved to …
Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan
Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan
Human–Wildlife Interactions
Mineral extraction sites that are restored to open water can increase bird-strike risk if they are planned near airports. This can generate conflict between the minerals industry and safeguarding authorities. To help resolve this potential conflict, it would be useful to predict how new restorations affect local water-bird populations so that mineral deposits can be exploited and restored in safeguarded zones without compromising flight safety. Bird abundances and movements at new restorations can be estimated with statistical models that use the environmental characteristics of restoration schemes as predictor variables. These models can improve guidance in safeguarding, provided that they comprise …
Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser
Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser
USDA Wildlife Services: Staff Publications
Canada geese (Branta canadensis) often cause significant damage when they strike aircraft. They are responsible for a reported minimum of $2.6 million in damage per year to civil aviation in the United States. Knowledge of goose movements in relation to airports would allow wildlife managers to allocate time and funds to manage those populations that pose the greatest threat to aircraft. We placed alpha-numeric neck collars on 300 Canada geese within 8 km of both John F. Kennedy International Airport (JFKIA) and LaGuardia Airport in New York, New York. We conducted weekly observations for 2 years within a …

Management Of Bayberry In Relation To Tree-Swallow Strikes At John F. Kennedy International Airport, New York, Glen E. Bernhardt, Zachary J. Paton, Lisa A. Kutschbach-Brohl, Richard A. Dolbeer
Human–Wildlife Interactions
Tree swallows (Tachycineta bicolor) have been a periodic bird-strike problem at John F. Kennedy International Airport (JFKIA), New York, New York, causing runway closures, flight delays, and damage to aircraft following the ingestion of bird flocks into engines. We examined 65 tree swallows collected at JFKIA in October 2001 to determine food sources that were attracting the birds to the airport. Digestive tracts of all 65 specimens contained northern bayberry fruits (Myrica pensylvanica), averaging 15.6 fruits per bird or 3.4% of the bird’s body mass in specimens where the entire tract was dissected. Bayberry fruits are …

Coexisting With Cougars: Public Perceptions, Attitudes, And Awareness Of Cougars On The Urban-Rural Fringe Of Calgary, Alberta, Canada, Clarisse Thornton, Michael S. Quinn
Human–Wildlife Interactions
Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population. We determined the attitudes, knowledge, and perceptions toward cougars by residents in the urban-rural fringe of Calgary, Alberta, Canada, an area populated by both cougars and humans. We sent a survey to a stratified, random sample of 1,508 residents. Survey analysis included a potential for conflict index (PCI) to help provide quantitative direction for future cougar management. We analyzed and tested for differences among 7 variables: livestock …
Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Richard A. Dolbeer, Sandra E. Wright
Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Richard A. Dolbeer, Sandra E. Wright
Human–Wildlife Interactions
The National Wildlife Strike Database for Civil Aviation in the United States became operational in 1995 with the initiation of data entry of all strike reports beginning in 1990. The database contained 82,057 reported strikes from 1990 to 2007. About 9,800 of these strike reports noted damage to the aircraft, of which 2,700 indicated the damage was substantial. The database has proven to be a useful source of objective information on the extent and nature of wildlife strikes for personnel at individual airports and for researchers and regulatory agencies at the national level. With the impending requirement for airports in …

Role Of Near-Miss Bird Strikes In Assessing Hazards, Matthew W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Begier
Role Of Near-Miss Bird Strikes In Assessing Hazards, Matthew W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Begier
Human–Wildlife Interactions
Management of problem wildlife within the airfield environment is a difficult job. Today’s Bird–Animal Aircraft Strike Hazard (BASH) program managers require as much information as possible to accomplish their tasks. Bird censuses and actual bird-strike events in and around the air operations area are used to make airfield management decisions and to assess the risk of bird hazards to aircraft. Both types of information are sampled rather sparsely. Avian radar is now being used as a new tool to provide continuous sampling of bird activity that significantly supplements visual censuses. The measure of risk used today is commonly expressed as …
Personal And Corporate Liability In The Aftermath Of Bird Strikes: A Costly Consideration, Larry A. Dale
Personal And Corporate Liability In The Aftermath Of Bird Strikes: A Costly Consideration, Larry A. Dale
Human–Wildlife Interactions
This paper details liability issues inherent in bird–aircraft collisions (bird-strike) incidents at airports and discusses how airport managers and operators must strive to conduct accurate assessments and develop and implement an effective wildlife management plan. Such efforts are mandated by Federal Aviation Administration (FAA) regulations, and failure to follow them may result in loss of human life and property, as well as large financial penalties for managers and operators and adverse media attention and public criticism for the airport authority.
Burrowing Owl And Other Migratory Bird Mitigation For A Runway Construction Project At Edwards Afb, Amber L. Hoen, Mark Hagan, Mark Bratton
Burrowing Owl And Other Migratory Bird Mitigation For A Runway Construction Project At Edwards Afb, Amber L. Hoen, Mark Hagan, Mark Bratton
Human–Wildlife Interactions
Edwards Air Force Base (AFB) scheduled the construction of a runway in the spring of 2007. The runway would be in an area that contained migratory birds and their habitat. The construction project would be near Edwards AFB main runway and had the potential not only to impact species protected under the Migratory Bird Treaty Act (MBTA), including the burrowing owl (Athene cunicularia), but also to increase bird and wildlife–aircraft strike hazards in the active flightline areas. To discourage nesting in the project area, reduce the potential for bird and wildlife–aircraft strikes, and maintain compliance with federal environmental …

A Decade Of U.S. Air Force Bat Strikes, Suzanne C. Peurach, Carla J. Dove, Laura Stepko
Human–Wildlife Interactions
From 1997 through 2007, 821 bat strikes were reported to the U.S. Air Force (USAF) Safety Center by aircraft personnel or ground crew and sent to the National Museum of Natural History, Smithsonian Institution, for identification. Many samples were identified by macroscopic and or microscopic comparisons with bat specimens housed in the museum and augmented during the last 2 years by DNA analysis. Bat remains from USAF strikes during this period were received at the museum from 40 states in the United States and from 20 countries. We confirmed that 46% of the strikes were caused by bats, but we …
Suspending Vulture Effigies From Roosts To Reduce Bird Strikes, Steven A. Ball
Suspending Vulture Effigies From Roosts To Reduce Bird Strikes, Steven A. Ball
Human–Wildlife Interactions
I observed very few vultures over the airfield after deploying the effigies, and vultures were completely absent most days. Hanging vulture effigies seemed to be effective in pushing the vultures farther away by denying them their observation point looking over the Coastal Plain near the airfield. This meant that their forage center point had been relocated far enough from the airfield that few individuals extended their range as far as the airport.
The Eradication Of Invasive Mammal Species: Can Adaptive Resource Management Fill The Gaps In Our Knowledge?, Sugoto Roy, Graham C. Smith, James C. Russell
The Eradication Of Invasive Mammal Species: Can Adaptive Resource Management Fill The Gaps In Our Knowledge?, Sugoto Roy, Graham C. Smith, James C. Russell
Human–Wildlife Interactions
Invasive alien species (IAS) threaten global biodiversity; they are the major cause of species extinction on offshore islands. Management of IAS requires data on the ecology of species in their new environment, how these species respond to management, and how these processes interact. Often, however, there is a paucity of information on key biological parameters that are critical to making management decisions. We sent a questionnaire to professionals and organizations managing invasive species and asked the respondents to prioritize a list of information they required to carry out eradication of invasive species. We analysed responses to assess the level of …
Translocation Of Nine-Banded Armadillos, Daniel J. Gammons, Michael T. Mengak, L. Mike Conner
Translocation Of Nine-Banded Armadillos, Daniel J. Gammons, Michael T. Mengak, L. Mike Conner
Human–Wildlife Interactions
During the last 150 years, nine-banded armadillos (Dasypus novemcinctus) have increased their range and abundance in the southeastern United States. When foraging, armadillos cause damage to agricultural crops, as well as structural damage to driveways and foundations. Homeowners frequently use translocation to reduce local armadillo abundance. Despite its popularity with the general public, however, the appropriateness of nuisance wildlife translocation presents concerns for biologists. Our objective was to address some of these concerns by examining survival and movements of translocated armadillos. We translocated 12 armadillos (9 male, 3 female) equipped with radio-transmitters and compared their survival and movements …

External Characteristics Of Houses Prone To Woodpecker Damage, Emily G. Harding, Sandra L. Vehrencamp, Paul D. Curtis
Human–Wildlife Interactions
Woodpecker (Picidae spp.) damage to houses and buildings is a widespread and locally severe problem, yet the probability and type of damage has never been quantified and related to home characteristics. Woodpeckers excavate holes in homes for a several reasons, mainly for building nest and roost cavities, drumming, and foraging for insects. We examined the external characteristics of houses that were contributing factors in attracting woodpeckers to bore holes in house siding and trim. From March 2001 through April 2002, we surveyed 1,185 houses in the town of Ithaca, Tompkins County, New York. Of the houses visited, 33% had …

Factors Contributing To The Success Of A Single-Shot, Multiyear Pzp Immunocontraceptive Vaccine For White-Tailed Deer, Lowell A. Miller, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian
Human–Wildlife Interactions
We evaluated 6 different porcine zona pellucida (PZP) preparations used as a single-shot vaccine for multiyear contraception of captive white-tailed deer (Odocoileus virginianus). The study compared 2 PZP preparation technologies from ImmunoVaccine Technologies ™ (IVT) and National Wildlife Research Center (NWRC) over a 7-year period. The study compared both the use of oil in an emulsion and in suspension delivery, as well as replacement of the oil with an alum adjuvant. The study demonstrated that the oil emulsion adjuvant provided the longest lasting response. PZP isolated by the IVT provides a longer-lasting response than the preparation used by …
A Review Of The Potential Of Fertility Control To Manage Brushtail Possums In New Zealand, Weihong Ji
A Review Of The Potential Of Fertility Control To Manage Brushtail Possums In New Zealand, Weihong Ji
Human–Wildlife Interactions
Brushtail possums (Trichosurus vulpecula) were introduced into New Zealand from Australia in the mid-1800s and became a major invasive pest. They damage native biodiversity by browsing and predation, and they are a disease risk to the livestock industry by acting as vectors of bovine tuberculosis (TB). Management of possums includes their eradication from some offshore islands and control by trapping, shooting, and poisoning on the mainland. Possums have been eradicated successfully from some islands and greatly reduced in abundance in other areas of high conservation value or where they are infected with TB. However, possums are still at …
House Cats As Predators In The Australian Environment: Impacts And Management, Christopher R. Dickman
House Cats As Predators In The Australian Environment: Impacts And Management, Christopher R. Dickman
Human–Wildlife Interactions
This paper provides an overview of the predatory activities of the house cat (Felis catus) in Australia, focusing principally on the interactions of domestic and stray cats with native species of prey. Like their free-living, or feral, counterparts, domestic cats take a broad range of prey, with small mammals, birds, and human-derived foods forming the bulk of the diet. Domestic and stray cats have contributed to declines of suburban populations of eastern barred bandicoots (Perameles gunnii) and superb lyrebirds (Menura novaehollandiae) in Victoria, Australia. The effects of cats on prey communities remain speculative. In …

Home Range And Habitat Use Of Feral Hogs In Congaree National Park, South Carolina, Brad A. Friebel, Patrick G. R. Jodice
Human–Wildlife Interactions
Feral hogs (Sus scrofa) are a widespread exotic species that currently occur in most states within the United States and are common throughout the southeastern United States. We radio-collared and tracked feral hogs from April 2005 to November 2006 in Congaree National Park (CNP), South Carolina, USA. The CNP is one of the largest and most intact tracts of old-growth, bottomland hardwood forest remaining in the United States. We measured home range size and determined habitat use for male and female hogs. The mean (± SE) home range sizes for male hogs (n = 7) and female hogs …

White-Tailed Deer Attacking Humans During The Fawning Season: A Unique Human–Wildlife Conflict On A University Campus, Ryan D. Hubbard, Clayton K. Nielsen
Human–Wildlife Interactions
Human–wildlife conflicts associated with suburban white-tailed deer (Odocoileus virginianus) populations have increased in the last 20 years. Primary threats to human health and safety associated with overabundant deer populations include deer–vehicle collisions, attacks on humans, disease, and damage to native and ornamental vegetation. During the fawning seasons (May–June) of 2005 and 2006, 13 confirmed incidences of white-tailed deer attacking humans occurred on the campus of Southern Illinois University–Carbondale. To our knowledge, no report exists that documents free-ranging does attacking humans during the fawning season. The attacks occurred at multiple locations on campus, with injuries to humans, including minor …

Deer Guards And Bump Gates For Excluding White-Tailed Deer From Fenced Resources, Kurt C. Vercauteren, Nathan W. Seward, Michael J. Lavelle, Justin W. Fischer, Gregaory E. Phillips
Human–Wildlife Interactions
White-tailed deer (Odocoileus virginianus) causing damage is a reoccurring theme in the realm of wildlife damage management, especially regarding human safety, disease transmission, and agricultural losses. Fences often are the only reliable long-term nonlethal means of controlling deer damage. The efficacy of fences, however, relies on their weakest link: human-operated gates. Although not overly time-consuming, the act of closing a gate appears to be a burden to individuals, resulting in open-access to an otherwise protected resource. We examined the efficacy of 2 alternatives to traditional gates to evaluate their potential to be used for excluding or containing deer. …
