  2. Microfaunal remains from the East Granary, Roman Vindolanda: Evidence for human–animal interactions.

    Contributor(s):: Deb Bennett, Robert M. Timm

    The East Granary situated within the Roman fort-village complex at Vindolanda was in active use from the early third through the late fourth centuries A.D. The architectural layout of the foundation of this building consists of five parallel channels cut by cross-flues at regular intervals, and...

  3. Transspecies urban theory: chickens in an African city

    Contributor(s):: Alice Hovorka

    New cultural animal geography offers conceptual tools for a reinterpretation of urbanization in Africa. This article applies transspecies urban theory to the existing literature on urban livestock in the developing world, as well as a case study of chickens in Botswana to demonstrate how cities...

  4. Ranging Behaviour of Commercial Free-Range Broiler Chickens 2: Individual Variation

    Contributor(s):: Peta S Taylor, Paul H Hemsworth, Peter J Groves, Sabine G Gebhardt-Henrich, Jean-Loup Rault

    Little is known about broiler chicken ranging behaviour. Previous studies have monitored ranging behaviour at flock level but whether individual ranging behaviour varies within a flock is unknown. Using Radio Frequency Identification technology, we tracked 1200 individual ROSS 308 broiler...

  5. Ranging Behaviour of Commercial Free-Range Broiler Chickens 1: Factors Related to Flock Variability

    Contributor(s):: Peta S Taylor, Paul H Hemsworth, Peter J Groves, Sabine G Gebhardt-Henrich, Jean-Loup Rault

    Little is known about the ranging behaviour of chickens. Understanding ranging behaviour is required to improve management and shed and range design to ensure optimal ranging opportunities. Using Radio Frequency Identification technology, we tracked 300 individual broiler chickens in each of four...

  6. Responses of Birds to Humans at a Coastal Barrier Beach: Napatree Point, Rhode Island

    Contributor(s):: Thomas W. Mayo, Peter W.C. Paton, Peter August

    Human activity is one of the most important factors affecting disturbance to birds that use coastal barrier beaches in southern New England. The barrier beach at Napatree Point, RI, provides important breeding habitat for several bird species, key stopover habitat for thousands of migrating...

  7. Wildlife Management of Canada Geese in New York State: A Departure from the Express Policies of New York's Environmental Conservation Law

    Contributor(s):: Loriann Vita

    Prolonged recreational hunting of Canada geese in New York State may be contributing to the degradation of the species and ecological damage throughout the state. Due to the recent significant changes in the resident and migratory populations of Canada geese throughout the Atlantic Flyway, a more...

  8. Prehistoric human impacts on California birds: evidence from the Emeryville Shellmound Avifauna

    Contributor(s):: John Broughton

    The abundance of artiodactyls, marine mammals, waterfowl, seabirds, and other animals in 18th- and 19th-century California astonished early explorers, and the incredible wildlife densities reported in their accounts are routinely taken as analogues for the original or pristine zoological...

  9. Swooping in the Suburbs; Parental Defence of an Abundant Aggressive Urban Bird against Humans

    Full-text: Available

    Contributor(s):: Daniel Lees, Craig D.h. Sherman, Grainne S. Maguire, Peter Dann, Adam P.a. Cardilini, Michael A. Weston

    Masked Lapwings, Vanellus miles, often come into ‘conflict’ with humans, because they often breed in close proximity to humans and actively defend their ground nests through aggressive behaviour, which typically involves swooping. This study examined whether defensive responses...

  10. Juvenile psittacine environmental enrichment

    Contributor(s):: Simone-Freilicher, E., Rupley, A. E.

  11. Politics and Preservation: The Endangered Species Act and the Northern Spotted Owl

    Contributor(s):: Mark Bonnett, Kurt Zimmerman

  12. Emergency Animal Management during Disasters

    Contributor(s):: Angela I. Dement

    Natural disasters such as hurricanes and wildfires continue to demonstrate how important it is to have local emergency and disaster management plans. Yet often, the need to care for livestock and family pets during emergencies is overlooked. The Texas Animal Health Commission (TAHC) wrote an...

  13. Epidemiology of Emerging Zoonoses in Israel

    Contributor(s):: Arnon Shimshony

    The epizootiologic, climatic, and ecologic conditions in the Middle East, combined with socioeconomic and agricultural structures in Israel, have created a unique and hazardous veterinary public health situation in this country. In this paper, emerging zoonotic diseases are newly introduced...

  14. Avian perching deterrents on ultrasonic sensors at airport wind-shear alert systems

    Contributor(s):: Michael L. Avery, Ann C. Genchi

    Preventing birds from perching on the sensor units of the Federal Aviation Administration’s Low Level Wind-shear Alert System (LLWAS) is crucial to its successful operation. In this study we evaluated, under controlled conditions, responses of brownheaded cowbirds (Molothrus ater), fish crows...

  15. Dietary comparisons of adult male Common Grackles, Red-winged Blackbirds, and Yellowheaded Blackbirds in north central North Dakota

    Contributor(s):: H. Jeffrey Homan, George M. Linz, William J. Bleier, Robert B. Carlson

    We compared the esophageal contents of adult male common grackles (Quiscalus quiscula), red-winged blackbirds (Agelaius phoeniceus),and yellow-headed blackbirds (Xanthocephalus xanthocephalus) collected in north central North Dakota from JUly through October 1989. Temporal variation in the diets...

  16. Distribution, abundance and habitat use of American white pelicans in the Delta Region of Mississippi and along the western Gulf of Mexico coast

    Contributor(s):: D. Tommy King, Thomas C. Michot

    Aerial surveys of American White Pelicans (Pelecanus erythrorhynchos) were conducted over coastal Louisiana and the delta region of Mississippi on 1-2 days during December, February, and April each year from 1997 to 1999. Additional surveys were conducted in coastal Texas and Mexico during...

  17. Role of near-miss bird strikes in assessing hazards

    Contributor(s):: Matthew W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Begier

    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...

  18. Comparison of nicarbazin absorption in chickens, mallards, and Canada geese

    Contributor(s):: C. A. Yoder, L. A. Miller, K. S. Bynum

    Nicarbazin (NCZ), a coccidiostat commonly used in the poultry industry, causes reduced hatchability and egg quality in layer hens at a concentration of 125 ppm (8.4 mg/kg) in the feed. Although this effect is undesirable in the poultry industry, NCZ could provide a useful wildlife contraception...

  19. Estimation of red-winged blackbird mortality from toxic bait application

    Contributor(s):: James F. Glahn, Michael L. Avery

    Application of slow-acting toxic bait is one method of reducing local populations of depredating blackbirds. Estimating numbers of birds killed in such baiting operations is difficult because affected birds die off-site and are seldom recovered. We conducted bioassays and flight pen studies of...

  20. The social transmission of feather pecking in laying hens: effects of environment and age

    Contributor(s):: McAdie, T. M., Keeling, L. J.

    Abnormal behaviours, such as feather pecking, can become an even greater problem if they spread through the flock. Domestic hens are a social species and it has been suggested that feather pecking behaviour can be socially transmitted from few feather pecking individuals to many. The purpose of...
