Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting , the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching.
It was rediscovered by the early ethologist Oskar Heinroth, and studied extensively and popularized by his disciple Konrad Lorenz working with greylag geese. [2] Lorenz demonstrated how incubator-hatched geese would imprint on the first suitable moving stimulus they saw within what he called a "critical period" between 13 and 16 hours shortly ...
Zur Naturgeschichte der Aggression, "So-called Evil: on the natural history of aggression") is a 1963 book by the ethologist Konrad Lorenz; it was translated into English in 1966. [1] As he writes in the prologue, "the subject of this book is aggression , that is to say the fighting instinct in beast and man which is directed against members of ...
Konrad Lorenz met Nikolaas Tinbergen in 1936 at the Leiden Instinct Symposium. [11] In 1937, Tinbergen and Lorenz worked on two projects, an experimental analysis of egg-rolling behavior in the greylag goose, supporting the fixed action pattern hypothesis, and the responses of various young birds to cardboard models of raptors and other flying ...
Konrad Lorenz observed that the young of birds such as geese and chickens followed their mothers spontaneously from almost the first day after they were hatched, and he discovered that this response could be imitated by an arbitrary stimulus if the eggs were incubated artificially and the stimulus were presented during a critical period that ...
Geese are important to multiple culinary traditions. ... the greylag goose was the subject of Konrad Lorenz's pioneering studies of imprinting behaviour. [32] Gallery
Another example of a behavior that has been described as a fixed action pattern is the egg-retrieval behavior of the greylag goose, reported in classic studies by Niko Tinbergen and Konrad Lorenz. [5] Like many ground-nesting birds, if an egg becomes displaced from the nest, the greylag rolls it back to the nest with its beak.
Konrad Lorenz, working with greylag geese and other animals such as water shrews, showed that ritualization was an important process in their development. [1] He showed that the geese obsessively displayed a reflexive motor pattern of egg retrieval when stimulated by the sight of an egg outside their nest.
