The hypothalamus responds to these motivations by regulating activity in the endocrine system to release hormones to alter the behaviour of the animal. [5] These hormones include epinephrine (adrenaline) to increase blood flow and heart rate for a sufficient fight-or-flight response, [6] and ghrelin, which is commonly described as "the hunger ...
Many animals express individual behavioral traits that are stable over time and context. Personality in animals has been investigated across a variety of different scientific fields including agricultural science, animal behaviour, anthropology, psychology, veterinary medicine, and zoology. [1]
Detour behaviour Some animals appear to have an advanced understanding of their spatial environment and will not take the most direct route if this confers an advantage to them. Some jumping spiders take an indirect route to prey rather than the most direct route, thereby indicating flexibility in behaviour and route planning, and possibly ...
Vigilance, in the field of behavioural ecology, refers to an animal's monitoring of its surroundings in order to heighten awareness of predator presence. Vigilance is an important behaviour during foraging as animals must often venture away from the safety of shelter to find food.
Autogrooming or self-grooming is any grooming behaviour performed by an animal on its own body. This behaviour typically includes licking, chewing, clawing, and rubbing. [10] [4] This comfort behaviour is typically performed for hygienic purposes as seen in the red squirrel. The red squirrel removes parasites and dirt from its fur by licking ...
Shimmering behaviour of Apis dorsata (giant honeybees). A group of animals fleeing from a predator shows the nature of herd behavior, for example in 1971, in the oft-cited article "Geometry for the Selfish Herd", evolutionary biologist W. D. Hamilton asserted that each individual group member reduces the danger to itself by moving as close as possible to the center of the fleeing group.
The behavior of a dog can not always be an indication of its friendliness. This is because when a dog wags its tail, most people interpret this as the dog expressing happiness and friendliness. Though indeed tail wagging can express these positive emotions, tail wagging is also an indication of fear, insecurity, challenging of dominance ...
Display behaviour is a set of ritualized behaviours that enable an animal to communicate to other animals (typically of the same species) about specific stimuli. [1] Such ritualized behaviours can be visual, but many animals depend on a mixture of visual, audio, tactical and chemical signals. [ 1 ]
