  1. Nest alternatives: Adding a wire partition to the scratch area affects nest use and nesting behaviour of laying hens in furnished cages

    Contributor(s):: Hunniford, Michelle E., Widowski, Tina M.

    Furnished cages (FC) are designed to accommodate highly motivated behaviour patterns like nesting; however, how hens perceive the resources provided in FCs is not fully understood. Our previous research of hens in FCs with a curtained nest (plastic mesh floor) and a scratch area (smooth plastic...

  2. Nest location preferences in zoo-housed orangutans

    Contributor(s):: Bastian, Meredith L., Glendinning, David R., Reddy, Alexandra J., Herrelko, Elizabeth S., Brown, Melba, Renner, Elizabeth, Thompson, Laurie

    Nest building is an advanced and complex activity that wild orangutans engage in, yet they do so on a daily basis and with potential safety consequences. Like their wild counterparts, zoo-housed orangutans also make nests when given adequate materials, yet comparatively little research has...

  3. Influence of egg oiling on colony presence of ring-billed gulls

    Contributor(s):: DeVault, Travis L., Schmidt, Paige M., Pogmore, Fred E., Gobeille, John, Belant, Jerrold L., Seamans, Thomas W.

  4. Generational habituation and current bald eagle populations

    Contributor(s):: Guinn, Jeremy E.

  5. Movements, habitat selection, associations, and survival of giant Canada goose broods in central Tennessee

    Contributor(s):: Dunton, E. M., Combs, D. L.

  6. Improved methods for deterring cliff swallow nesting on highway structures

    Contributor(s):: Delwiche, M. J., Coates, R. W., Gorenzel, W. P., Salmon, T. P.

  7. Mate choice, maternal investment and implications for ostrich welfare in a farming environment

    Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.

    At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

  8. Bringing the Endangered Barn Owl Back to McLean County, Illinois: Implementing a Local Nest Box Program

    Contributor(s):: Anna Groves

    Barn owls are an endangered species in Illinois, but populations have been known to increase where nest box programs have been implemented. In conjunction with the John Wesley Powell Audubon Society, a barn owl nest box program was established in McLean County and the surrounding area. Seventeen...

  9. Strategic use of straw increases nest building in loose housed farrowing sows

    Contributor(s):: Westin, R., Hultgren, J., Algers, B.

    In spite of domestication, sows are still genetically programmed to perform nesting behaviour close to farrowing. In order to facilitate nest building, a method for a strategic use of large quantities of straw has been developed by Swedish piglet producing farmers. The objectives of the present...

  10. Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth

    Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.

    Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...

  11. Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows

    Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.

    We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...

  12. Evidence of competition for nest sites by laying hens in large furnished cages

    Contributor(s):: Hunniford, M. E., Torrey, S., Bedecarrats, G., Duncan, I. J. H., Widowski, T. M.

    Furnished cages are designed to accommodate behaviour considered important to laying hens, particularly nesting behaviour. Few researchers have studied the degree of competition for nest sites or the extent to which the amount of nest space affects nesting behaviour in large furnished cages. We...

  13. Housing condition and nesting experience do not affect the Time to Integrate to Nest Test (TINT)

    Contributor(s):: Rock, M. L., Karas, A. Z., Gallo, M. S., Pritchett-Corning, K., Gaskill, B. N.

    Managing and assessing well-being in laboratory mice ( Mus musculus) is both challenging and necessary. Assessments intended to detect negative welfare states in mice are usually performed via observation of animals in the home cage, but a substantial amount of time and skill may be required to...

  14. Prepartum nest-building has an impact on postpartum nursing performance and maternal behaviour in early lactating sows

    Contributor(s):: Yun, JinHyeon, Swan, K. M., Farmer, C., Oliviero, C., Peltoniemi, O., Valros, A.

    The effects of facilitating prepartum nest-building (NB) behaviour, by providing abundant nesting materials, on postpartum maternal characteristics in early lactating sows were evaluated. A total of 35 sows, approximately seven days before the expected parturition date, were housed in: (1) CRATE...

  15. The physiological and behavioural impact of sensory contact among unfamiliar adult mice in the laboratory

    Contributor(s):: Rettich, A., Kasermann, H. P., Pelczar, P., Burki, K., Arras, M.

    Housing mice in the laboratory in groups enables social interaction and is the way a laboratory should house mice. However, adult males show reciprocal aggression and are therefore frequently housed individually. Alternatively, a grid divider, which allows sensory contact by sight and smell but...

  16. Human-dog interactions and behavioural responses of village dogs in coastal villages in Michoacan, Mexico

    Contributor(s):: Ruiz-Izaguirre, E., Eilers, K. H. A. M., Bokkers, E. A. M., Ortolani, A., Ortega-Pacheco, A., Boer, I. J. M. de

    In Mexican villages, most households keep dogs that roam freely. Therefore, socialisation of village dogs occurs in a different context than that of companion dogs in developed countries. The objectives of this study were: (1) to assess village dogs' behavioural responses towards familiar and...

  17. Differential preference for ultraviolet light among captive birds from three ecological habitats

    Contributor(s):: Ross, M. R., Gillespie, K. L., Hopper, L. M., Bloomsmith, M. A., Maple, T. L.

  18. Nest-building in sows: effects of farrowing housing on hormonal modulation of maternal characteristics

    Contributor(s):: Yun, JinHyeon, Swan, K. M., Vienola, K., Farmer, C., Oliviero, C., Peltoniemi, O., Valros, A.

  19. Effects of grackle damage control techniques in citrus on nesting success of non-target species

    Contributor(s):: John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores

    Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning...

  20. Metal concentrations in blood from an adult bald eagle nesting at Clinton Reservoir in Kansas

    Contributor(s):: George T. Allen

    Concentrations of metals in blood from an adult male bald eagle nesting at Clinton Reservoir in eastern Kansas in 1991 were analyzed by induction coupled plasma emission spectroscopy without preconcentration.Because there are very limited data on background levels of most metals in bald eagle...
