How do zoos affect animal behavior?
In contrast, most studies show that the presence of the public in zoos has a negative impact on animal behaviour, such as reducing social interactions (grooming, for example [14]). The same animals expressed more abnormal behaviours when they were observed by visitors.
How abnormal is the behavior of captive zoo living chimpanzees?
Our data support a conclusion that, while most behaviour of zoo-living chimpanzees is ‘normal’ in that it is typical of their wild counterparts, abnormal behaviour is endemic in this population despite enrichment efforts.
How does the zoo environment affect the behaviour of captive primates?
At their most extreme, captive environments can cause abnormal behaviours that are rarely if ever seen in wild environments, such as regurgitation and re-ingestion in gorillas (Akers and Schildkraut, 1985; Lukas, 1999) and stereotyped body rocking in chimpanzees (Pazol and Bloomsmith, 1993).
Do animals behave differently in zoos?
However, life in captivity differs substantially from life in the wild. Abnormal behaviour in captive animals can include stereotypic behaviours – highly repetitive, invariant, functionless behaviour, such as repetitive pacing, swaying, head-bobbing, bar-biting, over-grooming or excessive licking.
What is abnormal repetitive behavior?
Abnormal repetitive behaviors (ARBs) represent a diverse group of behaviors whose underlying mechanism is poorly understood. Their neurobiology likely involves several different neurotransmitter systems. These behaviors have been referred to as compulsive disorders, obsessive compulsive disorders and stereotypies.

What is abnormal dog behavior?
Stereotypies observed in kennelled dogs include circling, pacing, whirling, jumping, wall bouncing, repetitive grooming or self-biting, polydipsia or polyphagia, compulsive staring and an excessive propensity towards certain behaviours such as barking (see Hubrecht et al.
How do animals get Zoochosis?
Animals develop zoochotic behaviors when they are removed from their natural habitats. The other major cause of zoochosis is when animals are separated from their family. Gorillas are a good example of social animals that when separated from their families, they develop unusual habits like incessant sobbing.
What is the visitor effect?
Introduction. The zoo visitor effect is the change in behaviour and/or physiological responses of animals in the presence of zoo visitors (Davey, 2006). Such changes are often indicators of poor animal welfare, but, for certain species, human audiences are an enriching interaction (Hosey, 2000, Davey, 2006).
What are some examples of abnormal behaviors?
For example, a mouse continuing to attempt to escape when escape is obviously impossible. Behavior that violates the standards of society. When people do not follow the conventional social and moral rules of their society, the behavior is considered to be abnormal.
Does repetitive behaviors always mean autism?
Repetitive behaviors are among the first signs of autism to emerge in toddlerhood. They are seen in people across the autism spectrum. They tend to be more pronounced in those with lower cognitive ability, however. Repetitive behaviors have been recognized as part of autism since the condition was first described.
What makes an animal abnormal in a zoo?
When it comes to zoos and aquariums, we often hear of animals that demonstrate “abnormal” behaviours, often as a result of being in captivity.
How does the classification of abnormal behaviour work?
While classifying the abnormal behaviour one has to deal with a wide range of maladaptive responses. Besides, the symptoms of different mental diseases may be very similar but the causes may be quite different.
What are the issues with zoos and Aquaria?
ZOOS & AQUARIA – WHAT ARE THE ISSUES? There are tens of thousands of zoos worldwide, holding millions of wild animals in captivity. Born Free is concerned that zoos can never recreate the complex environment that animals have evolved to encounter in the wild and many animals suffer in captivity as a result.
When does a natural behaviour become harmful to an animal?
Some abnormal behaviours may have no obvious or immediate impact on the animals well-being, while others can become acutely harmful, very quickly. Finally, some behaviours considered abnormal for that species may actually be considered “normal” for an individual and consequently un-harmful or even positive in some cases.
