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. Although ...
The first English-language edition was published in 1952. The English title refers to the legendary Seal of Solomon, a ring that supposedly gave King Solomon the power to speak to animals. Lorenz claimed to have achieved this feat of communication with several species, by raising them in and around his home and observing their behavior.
Lorenz also found that the geese could imprint on inanimate objects. In one notable experiment, they followed a box placed on a model train in circles around the track. [2] Filial imprinting is not restricted to non-human animals that are able to follow their parents, however. The filial imprinting of birds was a primary technique used to ...
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.
Lorenz, Tinbergen, and von Frisch were jointly awarded the Nobel Prize in Physiology or Medicine in 1973 for their work of developing ethology. [6] Ethology is now a well-recognized scientific discipline, with its own journals such as Animal Behaviour, Applied Animal Behaviour Science, Animal Cognition, Behaviour, Behavioral Ecology and Ethology.
The studio sold an estimated $32 million on video, receiving 75% of the revenue. [23] The film was originally released to VHS in December 1996. A DVD release in August 2001 included the exclusive featurette by Bill Lishman, Operation Migration: Birds of a Feather, along with two documentaries: The Ultra Geese and the HBO special Leading the Flock.
Lorenz postulated that for each instinctive act there is a specific energy which builds up in a reservoir in the brain. In this model, Lorenz envisioned a reservoir with a spring valve at its base that an appropriate stimulus could act on, much like a weight on a scale pan pulling against a spring and releasing the reservoir of energy, an ...
In the late 1980s, Lishman approached Bill Carrick, a naturalist who was working on imprinting on the behaviour of geese. Carrick provided goslings, who Bill and his children worked with daily, eventually doing twice-daily runs on a motorcycle with the geese flying with him, then switching to the ultra-light. [2]
