The effects of radar on avian behavior: implications for wildlife management at airports
Contributor(s):: Sheridan, E., Randolet, J., DeVault, T. L., Seamans, T. W., Blackwell, B. F., Fernandez-Juricic, E.
Airports often contain foraging, breeding, and roosting resources for wildlife. Airports also have different types of radars to assist with air traffic control, monitoring weather, and tracking wildlife that could become a risk for collision with aircraft. The effect of radar electromagnetic...
Flight distance and reaction to fawn handling are greater in high- than in low-ranked pampas deer ( Ozotoceros bezoarticus) females
Contributor(s):: Ungerfeld, R., Morales-Pineyrua, J. T., Freitas-de-Melo, A.
The flight distance from humans and the reaction of the mother to human handling of their offspring are measures that can be used to assess the quality of the human-animal relationship which could vary according to animals' position in a group. The objective was to determine if the flight...
Behavioral and hormonal consequences of transporting giant pandas from China to the United States
Contributor(s):: Snyder, R. J., Perdue, B. M., Powell, D. M., Forthman, D. L., Bloomsmith, M. A., Maple, T. L.
Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress...

Exploration behaviour and flight response toward a stimulus in three sea bass strains ( Dicentrarchus labrax L.)
Contributor(s):: Millot, S., Begout, M. L., Chatain, B.
Domestication and selection may affect fish behaviour, sometime as soon as at the first generation of domestication. However, knowledge about how both processes impact on fish spatial exploration and swimming activity still is to be improved. The objective of this experiment was (i) to evaluate...
Fearfulness in horses: a temperament trait stable across time and situations
Contributor(s):: Lansade, L., Bouissou, M. F., Erhard, H. W.
The purpose of this study was to test the existence of a "fearfulness" trait in horses, by testing the stability across situations and over time of the responses to different fear-eliciting situations. It was also to identify which behavioural parameters are the best indicators of this trait....
Quality of handling and holding yard environment, and beef cattle temperament: 1. Relationships with flight speed and fear of humans
Contributor(s):: Petherick, J. C., Doogan, V. J., Holroyd, R. G., Olsson, P., Venus, B. K.
Numerous tests have been used to measure beef cattle temperament, but limited research has addressed the relationship between such tests and whether temperament can be modified. One-hundred-and-forty-four steers were given one of three human handling and yarding experiences on six occasions...
Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity
Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.
This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...
The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle
Contributor(s):: Olmos, G., Turner, S. P.
A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...
Responsiveness of dairy cows to human approach and novel stimuli
Contributor(s):: Gibbons, J., Lawrence, A., Haskell, M.
This study investigated intra-test and inter-test consistency of dairy cattle behavioural responses to a series of tests involving human approach and exposure to novelty. Thirty-six lactating Holstein-Friesian cows were each subjected to three human approach tests and three novel stimuli tests....
The effects of cage volume and cage shape on the condition and behaviour of captive European starlings ( Sturnus vulgaris )
Contributor(s):: Asher, L., Davies, G. T. O., Bertenshaw, C. E., Cox, M. A. A., Bateson, M.
Cage size is widely recognised as an important determinant of captive animal welfare, but in contrast, cage shape has received far less attention. Husbandry recommendations for flying birds state that cages should be long in shape because this allows greater potential for flight. However, so far...
Threat assessment by domestic ducklings using visual signals: implications for animal-machine interactions
Contributor(s):: Henderson, J. V., Wathes, C. M., Nicol, C. J., White, R. P., Lines, J. A.
There are increasing opportunities for robots to work amongst animals in agricultural systems. One potential application is in herding animals prior to catching or transportation. An effective herding robot must be able to interrupt ongoing animal behaviour without causing panic or flight...
Minimizing disturbance to wildlife by tourists approaching on foot or in a car: a study of kangaroos in the Australian rangelands
Contributor(s):: Wolf, I. D., Croft, D. B.
Approaching wildlife to attain a closer viewing experience is common amongst visitors to natural areas. We examined how tourists approach free-living kangaroos during encounters in a popular tourism destination in South Australia. We then simulated the typical properties of approaches to quantify...
The effect of early handling of foals on their reaction to handling, humans and novelty, and the foal-mare relationship
Contributor(s):: Sondergaard, E., Jago, J.
The natural behaviour of horses in response to danger is to take flight, and consequently human handlers can be injured. Reducing the flight response and general reactivity of horses is therefore likely to reduce the incidence of injuries to handlers. In this experiment we investigated the effect...
Effects of obstructed take-off and landing perches on the flight accuracy of laying hens
Contributor(s):: Moinard, C., Rutherford, K. M. D., Haskell, M. J., McCorquodale, C., Jones, R. B., Green, P. R.
Laying hens housed in extensive systems may be at risk of injury when many birds compete for use of the same perch space. Experiments were carried out to determine the space required by laying hens to move between obstructed perches. Eighty Lohmann Brown layer hens were reared in floor pens...
The effect of low energy electric shock on cortisol, beta -endorphin, heart rate and behaviour of cattle
| Contributor(s):: Lee, C., Fisher, A. D., Reed, M. T., Henshall, J. M.
Electrical stimuli are used increasingly to confine cattle, whether through conventional electric fencing or the development of 'virtual' fencing systems. Two experiments were conducted to assess behavioural, heart rate and stress hormone responses of cattle to electrical stimuli...
Fear reactions in trained and untrained horses from dressage and show-jumping breeding lines
| Contributor(s):: Borstel, U. U. K. von, Duncan, I. J. H., Lundin, M. C., Keeling, L. J.
Horses' fear reactions are hazardous to both horses and human beings, but it is not clear whether fear is influenced more by training or by other factors such as genetics. The following study was designed to detect differences between young, untrained (U) and older, well-trained (T) horses of...
Exploring heifers' perception of 'positive' treatment through their motivation to pursue a retreated human
| Contributor(s):: Bertenshaw, C. E., Rowlinson, P.
This pilot study investigates dairy heifers' perception of 'positive treatment' by a human (stroking and brushing) through a test of appetitive motivation. The hypothesis was that positive treatment by a human results in heifers pursuing a human to seek further positive treatment. Thirty-seven...
