Impact of diet and environmental enrichment management in stereotyped behaviours: a case study in tayra Eira barbara

Holistic approaches have been implemented to minimize stress expressed as stereotypies associated with low welfare conditions, which can arise from a range of factors such as frustration, adaptation attempts and neurological problems. Such behaviour was identified in a tayra housed in the facilities of the Santa Cruz Zoo (San Antonio de Tequendama, Colombia), for which […]

Appetitive Search Behaviors and Stereotypies in Polar Bears (Ursus maritimus)

Stereotypies in captive animals have been defined as repetitive, largely invariant patterns of behavior that serve no obvious goal or function. Stereotypies are commonly attributed to boredom or stress and are typically treated by enriching captivity with distracting, appealing stimuli. These stimuli often include food presented at times other than regular feedings, and as a […]

Evaluating the influence of conspecifics on a male giant anteater’s (Myrmecophaga tridactyla) pacing behavior

Stereotypic behavior has been studied in various species, but little information exists on stereotypies in giant anteaters (Myrmecophaga tridactyla) under professional care. Giant anteaters are known for their solitary nature and well-developed sense of smell. This study examined the effect of conspecifics who were housed off-exhibit on a male giant anteater’s rate of pacing and […]

Seasonal and Daily Activity of Two Zoo-Housed Grizzly Bears (Ursus Arctos Horribilis)

Captive grizzly bears, like their wild counterparts, engage in considerable variability in their seasonal and daily activity. We documented the year-long activity of two grizzly bears located at the Woodland Park Zoo in Seattle, Washington. We found that behaviors emerged in relation to month-to-month, seasonal, and time of day (hour-to-hour) observations, and events that occurred […]

Stereotypic behaviour predicts reproductive performance and litter sex ratio in giant pandas

Breeding and welfare problems confront many conservation breeding programs. Stereotypies—repetitive, unvarying, functionless behaviours —are common abnormal behaviours that often arise in suboptimal conditions. While the role of stereotypies in welfare assessment is well studied, few investigations address the relationship between stereotypic behaviour and reproduction. We examined the correlation between stereotypic behaviour and reproductive performance in […]

Animal Welfare: Could Adult Play be a False Friend?

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals could be the result of their “neotenic retardation.” Functional hypotheses have dealt with the long term benefits, such as “rehearsal,” […]

The effect of penning versus picketing on stereotypic behavior of circus elephants

The behavior of nine female Asian (Elephas maximus) elephants who performed two shows each day with a circus that traveled to a new location (40 to 250 km from the previous day’s lot) daily or every two days was studied during the 1996 and 1998 seasons. When not performing or working, the elephants were picketed […]

Wild Tigers in Captivity: A Study of the Effects of the Captive Environment on Tiger Behavior

Humans maintain wild animals in zoological parks for the purposes of education, conservation, research, and recreation. However, abnormal behaviors may develop in animals housed in human-made environments, if those environments do not allow them to carry out their natural behaviors (such as swimming, climbing, stalking, and predation). Captive environments in zoological parks often do not […]

Fish welfare: Current issues in aquaculture

With the continued growth of the aquaculture industry and increasing scientific discussion over the potential for negative events to give rise to suffering, research into the welfare of cultured fish is vital. How we define and measure welfare is cause for debate, particularly in fish. However, research into the effects of aquaculture procedures on welfare […]

Using The Observer for Animal Behavior Research: Stress and emotions in animals

Animals respond to inputs from their inner and outer environment with physiological and behavioral changes. They try to maintain a stable state by reacting to disturbances of the inner and outer world: their Umwelt. Under natural conditions an animal predicts and controls its Umwelt by feeding, moving, resting, socializing, communicating, etc. It has the freedom […]
