  2. Red Junglefowl Chicks Seek Contact With Humans During Foraging Task

    Full-text: Available

    | Contributor(s):: Diana Rubene, Hanne Løvlie

    Contact seeking with humans is documented in some domestic animals, mainly dogs, which have advanced communication skills. Domestication as a companion animal is thought to underlie this ability. However, also domesticated horses and goats display similar human-directed behaviors. This suggests...

  3. Identification of coronaviruses in farmed wild animals reveals their evolutionary origins in Guangdong, southern China

    | Contributor(s):: Wang, X., Ren, Z., Wang, L., Chen, J., Zhang, P., Chen, J. P., Chen, X., Li, L., Lin, X., Qi, N., Luo, S., Xiang, R., Yuan, Z., Zhang, J., Wang, G., Sun, M. H., Huang, Y., Hua, Y., Zou, J., Hou, F., Huang, Z., Du, S., Xiang, H., Sun, M., Liu, Q., Liao, M.

    Coronavirus infections cause diseases that range from mild to severe in mammals and birds. In this study, we detected coronavirus infections in 748 farmed wild animals of 23 species in Guangdong, southern China, by RT-PCR and metagenomic analysis. We identified four coronaviruses in these wild...

  4. Carcass Feeding for Captive Vultures: Testing Assumptions about Zoos and Effects on Birds and Visitors

    Full-text: Available

    | Contributor(s):: Hannah Gaengler

    Carcass feeding is a potentially controversial feeding method for zoo animals. The common assumption is that many North American zoos refrain from feeding large carcasses to their carnivorous animals because zoo visitors might not approve of this feeding method. However, since there are several...

  5. Furred and feathered friends: how attached are zookeepers to the animals in their care?

    | Contributor(s):: Melfi, V., Skyner, L., Birke, L., Ward, S. J., Shaw, W. S., Hosey, G.

    Keeper-animal relationships (KARs) appear to be important in zoos, since they can enhance the well-being of both the animals and the keepers, can make animal husbandry easier, but conversely might risk inappropriate habituation of animals and possible risks to the safety of keepers. It is,...

  6. Selection for reduced fear of humans changes intra-specific social behavior in red junglefowl - implications for chicken domestication

    | Contributor(s):: Gjoen, J., Jensen, P.

  7. Like Music to our Ears: The Complexity of Bird Vocalizations as a Key Factor of Attractiveness

  8. The Impact of Acute Loud Noise on the Behavior of Laboratory Birds

    Full-text: Available

    | Contributor(s):: Tayanne L. Corbani, Jessica E. Martin, Susan D. Healy

    Husbandry procedures and facility settings, such as low-frequency fire alarms, can produce noises in a laboratory environment that cause stress to animals used in research. However, most of the data demonstrating harmful effects that have, consequently, led to adaptations to management, have...

  9. Courtship Rituals: Imprinting and Interspecies Sociality in the Domestic Breeding of Birds of Prey

  10. Song of the Ovsîanka: Enhanced Nature of the Urban Canary in Imperial St. Petersburg (1880–1900)

  11. Assessing Owl Collisions with US Civil and US Air Force Aircraft

    Full-text: Available

    | Contributor(s):: Kimberly E. Linnell

    Collisions between wildlife and aircraft (wildlife strikes) pose notable risks. Previous research has found that a variety of birds and mammals are involved in wildlife strikes, but no comprehensive evaluation of collisions between owl and aircraft (owl strikes) has been conducted. We queried...

  12. Why the "Visitor Effect" Is Complicated. Unraveling Individual Animal, Visitor Number, and Climatic Influences on Behavior, Space Use and Interactions With Keepers—A Case Study on Captive Hornbills

    Full-text: Available

    | Contributor(s):: Paul E. Rose, Jake S. Scales, James E. Brereton

    A “visitor effect” on zoo-housed species has been documented since the 1970s, with research focused on mammals (specifically primates). To broaden our understanding of the “visitor effect” in a non-mammal, we conducted a case study on a pair of hornbills, recording...
