patterns of behaviour in animals pdf

The foraging behavior for which behavioral theory has had its greatest impact on community ecology is the balancing of risk of predation (or other costs of foraging) against food … When a movement is made very rapidly, there is simply no time to modify the movement — such as, the tongue flip of the toad towards the cockroach. This act is performed automatically and needs no prior experience. When the parent of song birds alights on the nest with food in their beak, it creates a jerk. Sherrington called it ‘reflex rebound’. Thus, inhibition of action would be as crucial as excitation. Nonetheless, it is important to keep these common principles in mind, so as to break-down complex behaviour patterns into smaller units, some of which may be similar to reflexes. However, it is the imposi­tion of a stable behaviour pattern in a young animal by exposure to particular stimuli during a critical period in the animal’s deve­lopment. The different controlling patterns of complex behaviour like fighting, feeding and sleeping compete for the control of the animal’s musculature. Charles Sherrington (1906), the father of modern neurophysiology, considered ways in which reflexes operate and how the central nervous system integrates them into adap­tive behaviour by combining information gathered from different sources, arranging them into sequences of action and allocating priorities. The results observed was very interesting. The long tail had the important function of balancing and the FAP once evolved persisted even when the morphological structure of long tail had dis­appeared. Similar FAP has been found to be exhibited by all individuals of a species (stereotype). This was amply exemplified by Sherrington (1917) from what he named as the cat’s ‘pinna reflex’. This induces the parent to regurgitate food called crop milk. It is also referred to as Fixed Action Pattern (FAP) or Innate Behaviour or Inborn Behaviour or Inherent Behaviour. It has great stability, often lasting for the rest of the animal’s life. Latency in response is exhibited by both reflexes and complex behaviour. 2. Review: Questions on Class 1 . David Stephens (1933), while agreeing with the above, has challenged the assump­tions about environmental stability saying that two types of stability need to be sepa­rated. The movements shown in Fig. He pioneered the idea of cognitive maps which is a mental model of the external environment, which may be con­structed following exploratory behaviour. Generally, young male rats do not respond unless any two such sources are available. The US, thus, is the cat odour. The female zebra finch, on the other hand, responded naturally with all the usual conspecific greeting calls and perched as close to the male as the partition allowed. Hinde (1954) found that when an owl is shown to chaffinches it shows a type of ‘warm-up’ effect. There are many instances of conditioned reflexes from our daily life. Abstract . 1. It lives in colonies and, while doing so, individuals typically lack the spines that are often used as a defence against predators. Advanced. Shortly after, they switched back to feeding again. Mutual inhibition allows them to take the lead in turn during the limb movements and to alternate flexion and extension of the limbs. (ii) Cloud- shadow passing overhead causes escape responses in young birds which gradually diminishes. Stephens has broken environmental predictability into two sections: (i) Predic­tability within the generation (lifetime) of an individual, and. Animal behaviour - Animal behaviour - Causation: At this level of analysis, questions concern the physiological machinery underlying an animal’s behaviour. By understanding behaviour one can predict, direct, change and control behaviour of individuals or group. Under no conditions does neither the mother wasp’s action nor the response of the larvae can rely on experience. Such type probably also occurs with com­plex behaviour, not only in the change of intensity but also in the nature of the behaviour. According to Thorpe (1960), learning also takes place even in those cases where no punishment or reward is associated. Unconditioned stimulus (US) is a stimulus that elicits a vigorous response in the absence of training. The drawback of instrumental learning is that it ignores the fact that behaviour was a continuous and free-flowing variable. The over-riding explanatory principle for animal behaviour is that of the theory of evolution, most often expressed not just in terms of the advantage of the individual, but by reference to the individual's genes. The simplest unit of behaviour is the reflex. Yet, equipped only with such fossil remains, scientists can get inklings about the behavior of extinct species. On the operation of the nerve cells, all behaviour depends. Inhibition at beha­vioural level means that behaviour which otherwise would have occurred is prevented from occurring by the action of another moti­vational system. Stimuli for imprinting may be visual, audi­tory or olfactory. The foraging behavior for which behavioral theory has had its greatest impact on community ecology is the balancing of risk of predation (or other costs of foraging) against food … Heyes (1994) has put forward three com­monly recognized types of experience that can lead to learning. The red spot present on the bill of herring gull is pecked by its chicks which acts as a sign stimulus. It has been observed with reflexes that the stronger the stimulus, the shorter the latency. Sounds, visual displays or chemicals used to attract a mate. America with those in Europe towards the study of animal behavior. ISBN: 0-226-08089-7 (cloth), 0-226-08090-0 (paperback) Ethology’s Ecologies We all know that history matters, but sometimes it is helpful to be reminded why. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. This can help them learn something new and useful, such as new skill in lessons, sport or at work. All these mechanisms are probably activated in some way by stim­uli to the ear, but their thresholds are differ­ent, with the laying back on the ear being the lowest threshold. Any stimulus that is considered to be positive, pleasant or rewarding is labeled as appetitive stimulus. Later, totally on her own, she selects a hollow stem and builds at its inner end, a partition of mud mixed with her saliva. (reproducti on) Behavior Patterns 5. Hamilton yThese and … Migration (movement during a season) 2. Innate behavior is something the animal is born knowinghow to do. It is a fixed action pattern (FAP). It may be defined as a behaviour which does not require learning or practice, but which appears spontaneously at the first instance of its need. Pavlovian conditioning was first deve­loped by Ivan Pavlov (1849-1936) in the late 1800’s. (b) Stimulus-stimulus (Pavlovian con­ditioning): In this case, instead of giving a single stimulus like the blue stick, it is paired with a second stimulus, say the odour of a cat (the odour of which the rats have an inherent fear). When an animal is stimulated, the obvious result is that the it makes a response. Another very interesting example of instinctive behaviour or FAP is provided by the Mason wasp (Manobia sp). The first type is innate behavior. Such dramatic results suggest how resistant sexual imprin­ting is to changes. If was observed that the foster-parent Bengalese females still remained a strong choice for courtship. The real situation includes other regulatory mechanisms that allows control over the muscle contractions involved in the maintenance of posture and also in move­ments. This type of response to mother figure is generally called ‘filial imprinting’ to contrast it with ‘sexual imprinting’. (ii) If sensitisation to a single cue has taken place, then it can be utilised for the association of other events. Metzgar observed that only two of twenty deer-mouse with previous experience of the hall were captured by the owl, while eleven of twenty mice with no prior experience of the habitat were caught. Let’s really dive in now and look at some easy ways to get started with your studies in animal behavior. It is species specific behaviour 3. After being satis­fied, she builds another partition sealing off the egg with its food supply. However, there is still some doubt over the relative merits of Pavlovian and instrumental learn­ing techniques. The nervous system is remarkable in the sense that it not only responds to stimuli but also possesses a remarkable ability to preserve the effect of previous stimuli for a shorter or longer period. About this page. She then plugs the outside end with mud (Fig. 1. Intact males have more aggressive behavior, whereas castrates are more docile after losing their source of male hormone. Another experiment conducted by Skinner was with pigeons where it learns to press a lever to open the door of a box to get food grains. It influences the animal’s adult social and sexual behaviour. It takes place only during a brief sen­sitive period early in the life. Instincts are extremely complex and include biological rhythms, territorial behaviour, courtship, mating, aggression, altruism, social hierarchies and social organization. �f����mwf. Complex beha­viour or reflex generally consists of a steady output of any activity. Stereotypic behaviors are repetitive, unvarying, and apparently functionless behavior patterns which captive animals may develop as a response to physical restraint, lack of stimulation, or inescapable fear or frustration. Instinctive Behaviours are genetically inherited characteristics that impel animals to behave in a certain fixed way. Williams yE.O. From Latin . ern behaviour at different age categories have unwritten rules that guide behaviour. In complex behaviour, the role of inhibi­tion is less obvious than that of excitation. Collective behaviour of animals has been a main focus of recent research, yet few empirical studies deal with this issue in the context of predation, a major driver of social complexity in many animal species. How do we maximize behaviors in an environment that is so different from the one in which the animal evolved its species-typical behaviors? Although this definition is of a negative kind, it emphasises the other fami­liar way in which behaviour can become matched to circumstances. survival value to the species. When the response is modified by past experience it is called conditioned reflex. A classical example of instrumental learning is provided in the case of a rat pressing some sort of lever to get food to drop into his cage. • Description • Audience • Impact Factor • Abstracting and Indexing • Editorial Board • Guide for Authors p.1 p.1 p.1 p.1 p.2 p.3 ISSN: 0003-3472 DESCRIPTION. The ability to learn is thought to be under some sort of complex genetic control, but whether this ability is favoured by natural selection is a matter of question. Definition of reproductive behaviour Reproductive Behaviour involve behaviour patterns associated with courtship, copulation, birth, maternal care and with suckling attempts of newborn. 1. Instincts involve complex and highly rigid pattern of behaviour involving numerous muscles, muscle groups, organs and systems that function in an entirely coordinated manner. For example, when we are standing at ease, our full body is evenly balanced over the pelvic girdle. Konrad Lorenz (1937) was the one who introduced imprin­ting through his experiments with geese, where he got broods of goslings to follow him and treat him as their mother figure. Experiments of Pavlovian condition­ing involve two stimuli-conditioned and unconditioned. Volume 2. Both appetitive and consummatory actions are dependent on the level of motiva­tion for that particular behaviour. The development of animal behaviour, therefore, involves many factors. Such learnings are unique and unlike other forms, is irreversible and restricted to a brief ‘critical period’ just after hatching. The important cue is the tiny gusts of wind produced by the toad’s movement which are picked up by the cock­roach through many tiny wind-sensitive hairs on its cerci.
