  1. Modification of aviary design reduces incidence of falls, collisions and keel bone damage in laying hens

    | Contributor(s):: Stratmann, A., Frohlich, E. K. F., Gebhardt-Henrich, S. G., Harlander-Matauschek, A., Wurbel, H., Toscano, M. J.

    Non-cage housing systems for laying hens such as aviaries provide greater freedom to perform species-specific behavior and thus are thought to improve welfare of the birds; however, aviaries are associated with a high prevalence of keel bone damage (fractures and deviations), which is a major...

  2. Welfare, health, and hygiene of laying hens housed in furnished cages and in alternative housing systems

    | Contributor(s):: Rodenburg, T. B., Tuyttens, F. A. M., Sonck, B., Reu, K. de, Herman, L., Zoons, J.

    The aim of this review was to compare welfare, health, and hygienic status of laying hens housed in furnished cages and in alternative systems. In alternative systems (floor housing and aviaries), birds have more freedom of movement and a more complex environment than in furnished cages. However,...

  3. A potential metric of the attractiveness of bird song to humans

    | Contributor(s):: Blackburn, T. M., Su, Shan, Cassey, P.

    The prevalence of passerines (mostly oscines, or songbirds) in international bird trade suggests that the possession or production of a song that is attractive or desirable to people may contribute to the likelihood of a species being traded. Testing this is difficult because we lack a general...

  4. Behaviour of Japanese quail (Coturnix japonica) kept in semi-natural aviaries

    | Contributor(s):: Schmid, I., Wechsler, B.

    Eight groups of 8 or 9 quails of a domestic strain were housed in aviaries (19.1 msuperscript 2) containing natural soil and vegetation from May to October 1994 in Switzerland. There were 2 groups with hens only and 6 groups of varied sex ratio. A time budget analysis showed that the quails spent...

  5. Cockatiels (Nymphicus hollandicus) reject very low levels of plant secondary compounds

    | Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.

    The rejection thresholds of caged cockatiels (Nymphicus hollandicus) were tested to determine their sensitivity to plant secondary compounds. Both alkaloids and tannins were tested using a two-bottle method in which purified water was always available in one bottle and an aqueous test solution...

  6. 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...

  7. Gender effects on aggression, dominance rank, and affiliative behaviors in a flock of captive adult cockatiels (Nymphicus hollandicus)

    | Contributor(s):: Seibert, L. M., Crowell-Davis, S. L.

    Agonistic and affiliative behaviours and spatial positioning were studied in a small psittacine species, N. hollandicus. Subjects studied were flock-housed breeders including 5 hens and 7 cocks. 15-minute focal animal samples were collected for the entire flock in a randomly distributed order...

  8. Reducing feather pecking when raising laying hen chicks in aviary systems

    | Contributor(s):: Huber-Eicher, B., Sebo, F.

    Aviary systems for laying hens offer several advantages over battery cages. However, pecking the feathers of conspecifics remains a serious problem that negatively affects the welfare of the birds as well as the economy of a farm. From experimental studies with small groups, it has been shown...

  9. Research approaches for improving the physical welfare and environment of laying hens

    | Contributor(s):: Tauson, R.

  10. Behavior problems of companion birds

    | Contributor(s):: Reisner, I. R.

  11. Feeding behaviour and daily energy expenditure of domesticated budgerigars (Melopsittacus undulatus): influence of type of housing and vertical position of the feeder

    | Contributor(s):: Schnegg, A., Gebhardt-Henrich, S. G., Keller, P., Visser, G. H., Steiger, A.

    Obesity is a common health problem in captive budgerigars (Melopsittacus undulatus). The welfare of budgerigars would be increased in a housing system limiting obesity. The aim of this study was to measure the influence of 3 different housing types on feeding behaviour and energy balance....

  12. Effect of rearing density on pecking behaviour and plumage condition of laying hens in two types of aviary

    | Contributor(s):: Hansen, I., Braastad, B. O.

    Chicks were reared on sand at high (H; 13/msuperscript 2) or low (L; 6.5/msuperscript 2) density, in 4 rearing pens of 390 chicks and 8 pens of 195 chicks, respectively, each pen measuring 30 msuperscript 2. Proportions of chicks per pen performing various types of pecking behaviour were recorded...

  13. Influence of rearing conditions of pullets on space use and performance of hens placed in aviaries at the beginning of the laying period

    | Contributor(s):: Colson, S., Arnould, C., Michel, V.

    Many studies have shown how laying aviaries can improve hens' welfare, but little work has been done on the adaptation of hens to this system according to their previous rearing conditions, despite the specific adaptation skills it requires of them. The adaptation to laying aviaries of hens...

  14. A comparison of the behaviour of solitary and group-housed budgerigars

    | Contributor(s):: Nicol, C. J., Pope, S. J.

    The behaviour of budgerigars housed in aviaries in a group of 6, or caged individually was studied over 2 months. Budgerigars in the aviary consumed more food and were more active, performing more wing stretching and flying. Caged birds vocalized more. When tested individually, the aviary birds...

  15. Welfare and mate choice in zebra finches: effect of handling regime and presence of cover

    | Contributor(s):: Collins, S. A., Archer, J. A., Barnard, C. J.

    Much attention has been focused, quite rightly, on the welfare of laboratory rodents and farm animals but certain other groups have been less well represented in welfare research. Small birds, for example, are often kept as pets and used in a wide variety of behavioural and physiological...

  16. Bird whisperer 101

    | Contributor(s):: Speer, B.

  17. Human-animal interaction - the place of the companion animal in society
