Signal fields and animal behaviour in the informative environment

The article is devoted to the problems of animal behaviour based on information, received by them through their habitat characteristics without direct visual contacts with their kind. Movement elements, behavioral reactions of similar motivation and parameters of the signal field, which represents an animal signal-information environment, may have some numerical expression and can be calculated depending on the research tasks. Formalization of the animal activity presupposes a composite consideration of three parameters: the extensiveness, the intensity and the duration of the behaviour.
