The scientific study of how animals behave, particularly in their natural environment
The tools of ethology were adapted, and applied ethology was born as a field of study
Behaviour of livestock/animals, as a key to handling them, received added attention after the development of large intensive systems of concentrated livestock production
The topic received even more attention after emphasis was given to animal welfare issues
Behaviour
Everything an animal does & how it does it
A behaviour is the nervous system's response to a stimulus and is carried out by the muscular or the hormonal system
Behaviour is subject to natural selection

Behaviour can occur in response to an internal or external stimulus
A sequence of unlearned, innate behaviours that is unchangeable. Once initiated, it is usually carried to completion. Triggered by an external cue known as a sign stimulus.
Areas of Study in Animal Behaviour
Communication (visual, auditory/vocal, olfactory/chemical, tactile/touch)
Aggression and Social Structure (dominance-related, territorial, pain-induced, fear-induced, maternal, predatory aggression)
Biological Rhythms and Sleep
Sexual Behaviour
Maternal Behaviour
Visual Communication
Leads to competition among males for the most impressive displays to attract females, wards off other male competitors, displayed through facial expressions and body language, alerts predators to the position of their prey
Vocal Communication
Made by the giving and receiving of audible noises from one animal to another, used to inform others of feeding, migration and location
Tactile communication/ Mechanoreception
Communication through the use of touch, including grooming in primates, and responding to physical stimuli like vibrations
Chemical communication
Using pheromones like alarm pheromones, sex pheromones, and trail pheromones
Bees provide an example of communication that involves chemical, tactile, and auditory components, including the "waggle dance" to communicate location of food
Competitive Behaviours
Competition for food, space, mates, and other resources occurs between individuals within a population
Agonistic Behaviour
A threatening or combative interaction between two individuals of the same species, usually involving intimidation and submission rather than injury
Dominance Hierarchies
A ranking system that helps reduce hostile behaviours among animals in a group, with a top-ranked "alpha" animal
Territorial Behaviours
Includes verbal signals, chemical signals, and physical defense of a geographic area, usually by males to increase their chance of obtaining adequate resources
Biological Rhythms
Cycles like the daily sleep/wake cycle, influenced by factors like light, barometric pressure, the endocrine system, and feeding
Courting Behaviours
Behaviours engaged in by animals to attract a mate, often involving displays, decorations, or fighting with rivals
Nurturing Behaviours
When parents provide care to their offspring in the early stages of development, including providing food, protection, and skills needed for survival
r mating
Includes jumping, dancing, singing or displaying decorations
Causes males to become more territorial and aggressive, often leading to a fight with rival suitors
Male grasshoppers can produce over 400 mating songs, each with different meaning
Maternal Behaviour
The ability of a female to care for her young, an important part of successful production of most livestock and companion species
Maternal Behaviour includes
Bonding behaviour between the female and her offspring
Mutual recognition
Negligence or neglect by the female
Nest-building
Nursing
Weaning
Learned behaviour
Nurturing Behaviours
When parents provide care to their offspring in the early stages of development
Animal species that spend time nurturing young often produce fewer offspring than animals that do not nurture
Sensitive periods and critical periods
Developmental stages when experience, or lack of it, has an influence on later behavior
Cognitive Behaviours
Thinking, reasoning, and processing information to understand complex concepts and solve problems
Insight Learning
The ability to do something right the first time with no prior experience, requiring reasoning ability
Observational Learning
The ability of an organism to learn how to do something by watching another individual do it first, even if they have never attempted it themselves
Young chimpanzees who watch their mothers crack nuts with rock tools before learning the technique themselves
