Animal Behaviour Vocabulary Quiz

Ethology is the scientific study of animal behaviour, particularly in natural environments. Ethologists observe how animals interact with each other and their environment, aiming to understand behaviour in terms of evolution, ecology and development. The field was pioneered by Konrad Lorenz, Nikolaas Tinbergen and Karl von Frisch, who shared the Nobel Prize in 1973.

Imprinting is a type of rapid learning that occurs during a critical period early in life, in which an animal forms a strong attachment to the first moving object it encounters — usually its mother. The most famous example is filial imprinting in birds, studied by Lorenz, where hatchlings follow the first large moving object they see. Imprinting is largely irreversible and influences future social and mating behaviour.

Habituation is one of the simplest forms of learning, in which an animal reduces or stops its response to a repeated stimulus that has proved neither harmful nor beneficial. For example, a bird that initially flies away when a car passes will eventually ignore it. Habituation is different from fatigue because the response can be quickly restored if the stimulus changes.

Foraging refers to the behaviour of searching for and obtaining food. Animals forage in ways that often maximise energy intake while minimising time and energy spent searching. Optimal foraging theory predicts that animals will select food types and patches that provide the greatest net energy benefit. Foraging strategies vary widely between species and are influenced by predation risk and food distribution.

Courtship behaviour refers to actions performed by an animal to attract a mate, signal fitness and initiate mating. It can include elaborate displays, songs, dances or physical competition. Examples include the dancing of birds-of-paradise and the antler combat of deer. Courtship behaviours are often species-specific and ensure mating occurs between individuals of the same species.

Camouflage is the use of colouring, patterns or body shape that allows an animal to blend into its surroundings and avoid detection. Types include background matching, disruptive colouration (bold patterns that break up the body outline) and masquerade (resembling an inedible object such as a leaf). Camouflage is a crucial survival strategy for many species.

Animal cognition refers to the mental processes of non-human animals, including perception, memory, problem-solving and learning. Research has shown that great apes, dolphins, crows and octopuses are capable of complex tasks such as tool use and self-recognition. The study of animal cognition challenges traditional views about the uniqueness of human intelligence.

A social hierarchy is a system of ranking within an animal group in which certain individuals have priority access to resources such as food and mates. It is typically established through aggressive encounters or displays. Well-known examples include the pecking order in chickens and rank structures in wolf packs. Hierarchies reduce the frequency of damaging fights by establishing predictable relationships.

Migration is the seasonal movement of animals from one region to another, typically in response to temperature, food availability or breeding requirements. Famous examples include the Arctic tern, which travels between the Arctic and Antarctic each year, and the wildebeest migration across the Serengeti. Migration involves complex navigation using magnetic fields, stars and landmarks.

Predation is an ecological interaction in which one organism (the predator) hunts, captures and consumes another (the prey). It drives natural selection through an evolutionary arms race: prey develop defences such as camouflage and speed, while predators develop better hunting strategies. Predation also regulates population sizes within ecosystems.
