Pigeons and Humans Time Miscued Intervals
| Contributor(s):: Shrinidhi Subramaniam
Cues signaling time to reinforcer availability can be highly informative, somewhat informative, or uninformative of the specific time to reinforcement. The purpose of this series of studies was to characterize the functional relation between miscues and pigeon and human response patterns in a...

Initial Observation of Human-Bird VocalInteractions in a Zoological Setting
| Contributor(s):: Rébecca Kleinberger, Janet Baker, Gabriel Miller
Vocal interactions between humans and non-human animals are pervasive, but studies are often limitedto communication within species. Here, we conducted a pilot exploration of vocal interactions betweenvisitors to the San Diego Zoo Safari Park and Sampson, an 18-year-old male Hyacinth Macaw...
Who Do Parrots Talk To? Agreeableness and a Serious Approach Increase the Production of Word-like Utterances by African Grey Parrots
| Contributor(s):: Jitka Lindova°
Label acquisition projects with the grey parrot (Psittacus erithacus) demonstrated cognitive and communicative skills of this species comparable to great apes. However, results differ profoundly between individuals and laboratories. Two studies investigated the relationship between the...

Feather Pecking and Cannibalism in Non-Beak-Trimmed Laying Hen Flocks—Farmers' Perspectives
| Contributor(s):: Eija Kaukonen, Anna Valros
Pecking-related problems are common in intensive egg production, compromising hen welfare, causing farmers economic losses and negatively affecting sustainability. These problems are often controlled by beak trimming, which in Finland is prohibited. An online questionnaire aimed to collect...
The Effect of Extensive Human Presence at an Early Age on Stress Responses and Reactivity of Juvenile Ostriches towards Humans
| 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...

Temperament in Captivity, Environmental Enrichment, Flight Ability, and Response to Humans in an Endangered Parrot Species
| Contributor(s):: Ramos, G. A. P., Azevedo, C. S., Jardim, T. H. A., Sant'Anna, A. C.
Temperament assessment is useful in reintroduction programs. Reactivity to humans and flight ability are also important behavioral aspects for captive parrots candidates to reintroduction. The study aimed: a) to evaluate if behavioral responses to environmental enrichment differ as a function of...
Reproduction and monogamy in captive flock of greater flamingos (Phoenicopterus Roseus)
| Contributor(s):: Sandri, Camillo, Sammarini, Carolina, Regaiolli, Barbara, Spiezio, Caterina, Piccirillo, Alessandra
Due to the great number of greater flamingos in captivity and their long life span, studying their behavior and welfare might be useful to improve the husbandry and breeding of this species in zoos. This study aimed to investigate factors affecting the breeding activity of captive greater...

Assessment of Non-Contact Infrared Thermometer Measurement Sites in Birds
| Contributor(s):: Anderson, Jessica, Kaplan-Stein, Sara, Adolph, Stephen, Peralta, Jose M.
The standard method of obtaining body temperature in a bird can be a stressful event, making routine evaluations challenging. Twenty-eight privately owned birds in good health were enrolled in the study to compare digital and infrared (IR) temperature readings. Digital thermometer readings in the...
Pain-suppressed behaviors in the red-tailed hawk (Buteo jamaicensis)
| Contributor(s):: Mazor-Thomas, Jana E., Mann, Phyllis E., Karas, Alicia Z., Tseng, Flo
Our ability to provide analgesia in wild and exotic patients is hampered by a lack of species-specific information on effective drugs and protocols. One contributing factor is the difficulty of applying data from traditional laboratory tests of nociception to clinical conditions frequently...
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...
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...
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...
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...
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...
