    Full-text: Available

    | Contributor(s):: Pfunzo T. Muvhali, Maud Bonato, Anel Engelbrecht, Irek A. Malecki, Denise Hough, Jane E. Robinson, Neil P. Evans, Schalk W. P. Cloete

    The effect of extensive human presence and regular gentle handling performed at an early age (0–3 months old) on stress responses and reactivity of juvenile ostriches towards humans was investigated. A total of 416 ostrich chicks over two years were exposed to one of three treatments for...

  2. Efficacy of foraging enrichments to increase foraging time in Grey parrots (Psittacus erithacus erithacus)

    | Contributor(s):: van Zeeland, Yvonne R. A., Schoemaker, Nico J., Ravesteijn, Manon M., Mol, Marjon, Lumeij, Johannes T.

    Foraging enrichment is considered one of the most effective strategies to improve welfare and reduce stereotypies and other abnormal repetitive behaviours in captive animals, including parrots. Few studies, however, have investigated the effects of the different types of enrichment and determined...

  3. Do hens have friends?

    | Contributor(s):: Abeyesinghe, Siobhan M., Drewe, Julian A., Asher, Lucy, Wathes, Christopher M., Collins, Lisa M.

    Recent interest in positive welfare has encouraged consideration of the formation of socio-positive relationships in farmed species which may provide a means by which to manage positive states. We investigated in detail the existence of dyadic preferential associations in small groups of domestic...

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

    | Contributor(s):: Ross, Megan R., Gillespie, Katie L., Hopper, Lydia M., Bloomsmith, Mollie A., Maple, Terry L.

    With receptors for red, blue, green, and ultraviolet-A light, birds have tetrachromatic vision. For birds, ultraviolet (UV) light is important for a number of their behaviors, including mate selection, foraging, and nesting. Many captive birds, however, are housed indoors without access to...

  5. Changes in position and quality of preferred nest box: Effects on nest box use by laying hens

    | Contributor(s):: Riber, Anja B., Nielsen, Birte L.

    Using laying hens, we investigated whether position of a nest box, both within the pen and relative to other nest boxes, influenced the preference for a nest box, and how a sudden and marked change to the preferred box influenced the use of nest boxes by the hens. Groups (n=12) of 15 Isa Warren...

  6. Behavioural testing to determine differences between coping styles in Grey parrots (Psittacus erithacus erithacus) with and without feather damaging behaviour

    | Contributor(s):: van Zeeland, Yvonne R. A., van der Aa, Marleen M. J. A., Vinke, Claudia M., Lumeij, Johannes T., Schoemaker, Nico J.

    In various animal species, a correlation has been found between the individual's response to ‘stressing’ stimuli (coping style) in behaviour tests and the susceptibility to develop behavioural disorders. Based on analogies with feather pecking in laying hens, a similar correlation might be...

  7. Aggressiveness in the domestic fowl: Distance versus ‘attitude’

    | Contributor(s):: Rodriguez-Aurrekoetxea, Ane, Estevez, Inma

    It has been suggested that invasion of the personal space by flock members is the main trigger of aggressive interactions in the domestic fowl (Gallus gallus domesticus). In large and dense groups of birds high frequency of attacks should be expected as the chances of invading the personal space...

  8. Personality traits and the effects of DHA supplementation in the budgerigar (Melopsittacus undulatus)

    | Contributor(s):: Callicrate, Taylor Eilers, Siewerdt, Frank, Koutsos, Elizabeth, Estévez, Inma

    We investigated the hypotheses that a bold-shy personality axis exists in the budgerigar (Melopsittacus undulatus) and that dietary docosahexaenoic acid (DHA) supplementation has a significant effect on budgerigar personality and immune responses. DHA is an integral component of the brain known...

  9. Nest sharing under semi-natural conditions in laying hens

    | Contributor(s):: Riber, Anja Brinch

    Under natural conditions, the feral hen (Gallus gallus domesticus) will choose a nest location away from the flock, whereas under commercial conditions, the domestic hen will often choose the same nest as other hens have used or are still using. Simultaneous nest sharing causes several welfare...

  10. Difference of social motivation in quail selected for divergent circadian activity

    | Contributor(s):: Formanek, Laureline, Richard-Yris, Marie-Annick, Petton, Christophe, Houdelier, Cécilia, Lumineau, Sophie

    Endogenous rhythms are adaptive responses to predictable changes of the environment, like the day/night cycle. Some researches demonstrated that social cycles can influence the circadian rhythm, while no study investigated the effect of endogenous rhythmicity on the sociability in Vertebrates....

  11. Comparing fostering success between wild-caught and game farm bred captive red-legged partridges (Alectoris rufa, L.)

    | Contributor(s):: Sánchez-García, Carlos, Alonso, Marta Elena, Pérez, José Antonio, Rodríguez, Pedro Luis, Gaudioso, Vicente Ramiro

    As fostered game birds are better prepared for releasing in comparison to those intensively reared, fostering of wild and game farm red-legged partridges (Alectoris rufa) was studied on a semi-natural rearing farm using farm-hatched chicks. Parent pairs, barren pairs and single individuals from...

  12. The Human-Animal Relationship in Australian Caged Laying Hens

    Full-text: Available

    | Contributor(s):: Lauren E. Edwards, Grahame J. Coleman, Kym L. Butler, Paul H. Hemsworth

    Studies on farm animals have shown relationships between stockperson attitudes and behaviour and farm animal fear, stress and productivity. This study investigated how the avoidance behaviour of Australian commercial caged laying hens may be related to stockperson behaviour, albumen...

  13. Animal Welfare in Conservation Breeding: Applications and Challenges

    Full-text: Available

    | Contributor(s):: Alison L. Greggor, Greg A. Vicino, Ronald R. Swaisgood, Andrea Fidgett, Deena Brenner, Matthew E. Kinney, Susan Farabaugh, Bryce Masuda, Nadine Lamberski

    Animal welfare and conservation breeding have overlapping and compatible goals that are occasionally divergent. Efforts to improve enclosures, provide enriching experiences, and address behavioral and physical needs further the causes of animal welfare in all zoo settings. However, by...

  14. Parroting patriots: interspecies trauma and becoming-well-together

    | Contributor(s):: Bolman, B.

  15. More eggs but less social and more fearful? Differences in behavioral traits in relation to the phylogenetic background and productivity level in laying hens

    | Contributor(s):: Dudde, Anissa, Schrader, Lars, Weigend, Steffen, Matthews, Lindsay R., Krause, E. Tobias

    Different lines of laying hens have undergone a strong selection pressure for productivity traits, which has been proposed as a potential cause of undesirable side effects like behavioural disorders. One reason for such behavioral changes might be due to energy trade-offs, as high productive...

  16. Flock size during rearing affects pullet behavioural synchrony and spatial clustering

    | Contributor(s):: Keeling, Linda J., Newberry, Ruth C., Estevez, Inma

    Animals are often synchronised in their behaviour, with costs and benefits varying according to group size and the behaviour being performed. Making decisions about optimal allocation and distribution of resources to animals in our care therefore poses theoretical and practical challenges. We...

  17. Social bonds in a flock bird: Species differences and seasonality in social structure in captive flamingo flocks over a 12-month period

    | Contributor(s):: Rose, Paul E., Croft, Darren P.

    Social network analysis (SNA) is a popular tool for investigating key components of sociality in free-living populations, and is growing in its application to captive animal systems. For social species held in captivity, welfare may be improved if protocols for care take key aspects of sociality...

  18. Exposing avian embryos to light affects post-hatch anti-predator fear responses

    | Contributor(s):: Archer, Gregory S., Mench, Joy A.

    Environmental stimuli present during incubation can impact the behavior of birds post-hatch. To determine the effect of exposing broiler chicken embryos to light on fear-related behavior post-hatch, we conducted two experiments in which we incubated eggs under various light schedules, and then...

  19. The effect of auditory enrichment, rearing method and social environment on the behavior of zoo-housed psittacines (Aves: Psittaciformes); implications for welfare

    | Contributor(s):: Williams, Isabelle, Hoppitt, Will, Grant, Rachel

    The psychological and physiological effects of different genres of music are well documented in humans. These concepts have also been studied in kenneled dogs and some exotic animals, implying that animals may experience benefits similar to those of humans. This study tested the hypothesis that...

  20. Effects of visual obstruction, prey resources, and satiety on bird use of simulated airport grasslands

    | Contributor(s):: Blackwell, Bradley F., Seamans, Thomas W., Linnell, Kimberly, Kutschbach-Brohl, Lisa, DeVault, Travis L.

    Grasslands represent 39%–50% of U.S. airport properties, and a recent management framework recommended exploiting both antipredator behaviours and food resources in airport grasslands to curb use by birds considered hazardous to aviation safety. We evaluated framework predictions empirically by...
