In 1937 Lorenz wrote: "With head and eyes the bird made a motion as though following a flying insect with its gaze; its posture tautened; it took off, snapped, returned to its perch, and with its bill performed the sideways lashing, tossing motions with which many insectivorous birds slay their prey against whatever they happen to be sitting ...
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 ...
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 Zacharias Lorenz (Austrian German pronunciation: [ˈkɔnʁaːd tsaxaˈʁiːas ˈloːʁɛnts] ⓘ; 7 November 1903 – 27 February 1989) was an Austrian zoologist, ethologist, and ornithologist.
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 after hatching. For example, the goslings would imprint on Lorenz himself (to be more specific, on his wading boots), and he is often depicted being followed by a ...
Richard Dawkins noted that Lorenz was a " 'good of the species' man" [7] so accustomed to group selection thinking that he did not realize his views "contravened orthodox Darwinian theory". [7] The ethologist Niko Tinbergen praised Lorenz for his interest in the survival value of behavior, and naturalists enjoyed Lorenz's writings for the same ...
Konrad Lorenz and Nikolaas Tinbergen. Konrad Lorenz had examined the phenomenon of "imprinting" and felt that it might have some parallels to human attachment. Imprinting, a behavior characteristic of some birds and a very few mammals, involves rapid learning of recognition by a young bird or animal exposed to a conspecific or an object or ...
In developmental psychology and developmental biology, a critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli. If, for some reason, the organism does not receive the appropriate stimulus during this "critical period" to learn a given skill ...
