... Actividades de desplazamiento
Este comportamiento fue descrito por primera vez, independientemente, por Tinbergen y A. Kortlandt en 1940. La característica principal de esta conducta es su aparente irrelevancia respecto al contexto en que se da, ocurriendo con frecuencia en situaciones de conflicto entre realizar al mismo tiempo dos comportamientos incompatibles. Además, los propios actos del desplazamiento suelen ser actividades que se repiten mucho en la rutina ordinaria del animal (tales como alimentarse, o rascarse). ... También, durante una disputa territorial o pelea, los escribanos nivales (Plectrophenax nivalis), alondras cornudas (Eremophila alpestris) o los gallos (Gallus g. domesticus) implicados muestran conflicto entre atacar o apartarse del contrario, mostrando entonces con frecuencia la actividad de desplazamiento de picotear el suelo, como si se alimentaran (Howard 1929, Pickwell 1931, Lorenz 1935, Tinbergen 1939). ...

... Por ejemplo, se le suministra comidaa una paloma; "algo" le indica: "acércate, come", mientras otro "algo" le susurra a su cerebro: "huye, esta situación es sospechosa". La consecuencia del conflicto es que la paloma se mantiene a una distancia intermedia y se atusa las plumas (actividad de desplazamiento). Esto podría explicar la aparición de DC (Martín, 2016). ...

... El esquema patrón motorde la esterotipia se desarrolla a menudo a partir de un movimiento de intención o de una actividad de desplazamiento. En el primer caso el esquema de comportamiento puede ser una indicación relacionada con el origen de la motivación frustrada de modo que se puede reaccionar de manera correctiva, es decir, adaptando el medio ambiente a las necesidades del animal. Probablemente muchas esterotipias tienen un origen mutifactorial, es decir, que el comportamiento normal es el resultado de una combinación de diferentes factores. ...

... Displacement activity, the performance by an animal of an act inappropriate for the stimulus or stimuli that evoked it. Displacement behaviour usually occurs when an animal is torn between two conflicting drives, such as fear and aggression. Displacement activities often consist of comfort movements, such as grooming, scratching, drinking, or eating. In courtship, for example, an individual afraid of its mate may, instead of fleeing or courting, stand still and feed or groom itself. ...

... displacement activity
Quick Reference
An activity shown by an animal that appears to be irrelevant to its situation. Displacement activities are frequently observed when there is conflict between opposing drives. For example, birds in aggressive situations, in which there are simultaneous drives to attack and to flee, may preen their feathers as a displacement activity. ...

Displacement Activities and Arousal
... Abstract
IN 1940 Tinbergen1 and Kortlandt2 independently drew attention to a behavioural phenomenon which has since been called displacement activity and has received a good deal of attention3,4. Although no binding rules exist by which displacement behaviour can be recognized, the term is applied to behaviour patterns which appear to be out of context with the behaviour which closely precedes or follows them, either in the sense that they do not seem functionally integrated with the preceding or following behaviour or that they occur in situations in which causal factors usually responsible for them appear to be absent or at least weak compared with those determining the behavioural envelope. Displacement activities occur in three situations: motivational conflict, frustration of consummatory acts and physical thwarting of performance. Several theories have been put forward to explain the causal mechanism involved 5–8. ...

... displacement activity The behaviour of an animal which is or appears to be irrelevant to the situation in which it occurs and which may interrupt other activity. It may result from conflicting motivation, in which two motivations cancel one another, allowing a less urgent motivation (e.g. feeding) to dominate behaviour; or it may arise because the animal is prevented from attaining a goal, and the consequent frustration causes the attention to be switched to another stimulus to which it then responds. ...
