  1. Factors affecting nest choice by Pekin ducks

    Contributor(s):: Makagon, Maja M., Tucker, Cassandra B., Mench, Joy A.

    To encourage nest use in breeder poultry flocks, it is important that nest boxes are attractive. Few studies have evaluated factors affecting nest attractiveness to ducks. We assessed the effects of nest box experience (Experiments 1 and 2) and features of nests, including degree of enclosure...

  2. Maternal nest building and choice of nest site are temperature dependent in mink: Parent-offspring temperature conflict?

    Contributor(s):: Schou, Toke Munk, Malmkvist, Jens

    We investigated whether nest building and nest site preference are temperature dependent in female mink. We designed two experiments: in Experiment 1, female mink had access to unheated (7 °C, Room7C group) or heated (25 °C, Heated25C group) nest boxes; in Experiment 2, female mink had free...

  3. Relative preference for wooden nests affects nesting behaviour of broiler breeders

    Contributor(s):: van den Oever, Anna C. M., Rodenburg, T. Bas, Bolhuis, J. Elizabeth, van de Ven, Lotte J. F., Hasan, Md Kamrul, van Aerle, Stephanie M. W., Kemp, Bas

    Optimising nest design for broiler breeders has benefits for both the animals and the producers. The welfare of the hens will increase by providing preferred housing, while also reducing eggs laid outside the nests. These floor eggs cause economic losses by compromised automatic egg collection...

  4. Resting preferences and welfare of Finnraccoon (Nyctereutes procyonoides ussuriensis) females housed in various housing conditions in winter

    Contributor(s):: Koistinen, Tarja, Raatikainen, Sini, Sepponen, Juhani, Korhonen, Hannu T.

    Raccoon dog (Nyctereutes procyonoides ussuriensis) is the only canid species using facultative passive wintering strategy. The aim of the present study is to document the behaviour and welfare of the farmed variant of the species, i.e. Finnraccoon, housed in various conditions in winter. Young...

  5. 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.

  6. Generational habituation and current bald eagle populations

    Contributor(s):: Guinn, Jeremy E.

  7. Do artificial nests simulate nest success of greater sage-grouse?

    Contributor(s):: Dinkins, Jonathan B., Conover, Michael R., Mabray, Scott T.

  8. A rat-resistant artificial nest box for cavity-nesting birds

    Contributor(s):: Pitt, W. C., Driscoll, L. C., VanderWerf, E. A.

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

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

  10. Effects of variation in nest curtain design on pre-laying behaviour of domestic hens

    Contributor(s):: Ringgenberg, N., Frohlich, E. K. F., Harlander-Matauschek, A., Toscano, M. J., Wurbel, H., Roth, B. A.

    Laying hens in loose-housing systems select a nest daily in which to lay their eggs among many identical looking nests, they often prefer corner nests. We investigated whether heterogeneity in nest curtain appearance - via colours and symbols - would influence nest selection and result in an even...

  11. Nest choice in laying hens: effects of nest partitions and social status

    Contributor(s):: Ringgenberg, N., Frohlich, E. K. F., Harlander-Matauschek, A., Toscano, M. J., Wurbel, H., Roth, B. A.

    Nest choice in loose-housed laying hens is influenced by nest characteristics, position and social factors. We examined the relative preference of laying hens for two group-nests differing in the presence or absence of a partition in the middle of the nest and whether this was influenced by...

  12. Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink

    Contributor(s):: Malmkvist, J., Palme, R.

    Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...

  13. The reliability of welfare assessment according to the WelFur-protocol in the nursing period of mink (Neovison vison) is challenged by increasing welfare problems prior to weaning

    Contributor(s):: Henriksen, B. I. F., Moller, S. H.

    The objective of this study was to test the hypothesis that the body condition of the mink dam, the frequency of dirty nests, frequency of injuries and diarrhoea change significantly with the day of assessment, post-partum, within the data collection period from parturition to weaning,...

  14. The influence of the location of a nest box in an individually ventilated cage on the preference of mice to use it

    Contributor(s):: Kostomitsopoulos, N. G., Paronis, E., Alexakos, P., Balafas, E., Loo, P. van, Baumans, V.

    The improvement of housing conditions for mice by using environmental enrichment materials is of high concern for the scientific community. Plastic, autoclavable nest boxes are commercially available and ready to use for specific cases such as in individually ventilated cages, metabolic cages, or...

  15. Variables Influencing Nest Success of Eastern Wild Turkeys in Connecticut: Nesting Habitat, Home Range-Scale Fragmentation, and Nest Attentiveness

    Contributor(s):: Shelley M. Spohr, Daniel J. Harrison (adviser), Frederick A. Servello (adviser)

    Nest success is the most important demographic parameter influencing rates of population change of eastern wild turkeys and many variables operating at multiple spatial and temporal scales may influence whether a nest is successful. Most studies of nest success and survival of turkeys have...

  16. Notes on the Owls Found in Lincoln County, Nebraska

    | Contributor(s):: Wilson Tout

    During more than a quarter of a century I have been making notes and collecting information about the Owls of Lincoln county and it seemed an opportune time to put this information into print that it might be available to those who are interested in birds and serve as a basis for further study...

  17. A model to predict the likelihood of cliff swallow nesting on highway structures in northern California

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

  18. The effect of investigator disturbance on egg laying, chick survival and fledging mass of short-tailed shearwaters (Puffinus tenuirostris) and little penguins (Eudyptula minor)

    | Contributor(s):: Vertigan, C., McMahon, C. R., Andrews-Goff, V., Hindell, M. A.

  19. Determinants of reproductive success in force-re-paired cockatiels ( Nymphicus hollandicus )

    | Contributor(s):: Stone, E. G., Millam, J. R., El-Halawani, M. E., Phillips, R. E., Redig, P. T.

    58 previously paired cockatiels were re-paired with mates with which they had never been previously paired. Males (M) and females (F) were assigned a breeding history that was 'experienced' (E) or 'inexperienced' (I), depending on whether they were part of a pair that had hatched at least one egg...

  20. Maternal behaviour in Mus musculus sp.: an ethological review

    | Contributor(s):: Weber, E. M., Olsson, I. A. S.

    In this paper, we review the scientific literature on maternal behaviour in commensal house mice and laboratory mice. Similar to other altricial species, female mice prepare a nest before parturition. Once the pups are born, nursing is the main part of maternal behaviour, and pups are weaned...
