The mechanisms of generating alarm calls of different bird species, species-specific calls of closely related species, and intraspecific differences in calls were analyzed. These mechanisms proved to be basically the same: variation of temporal parameters within the frequency range limited by morphological structures of the vocal apparatus. This principle(More)
A model for processing of acoustic information in neuron networks has been proposed. The model takes into account the final rate of transfer of electric signal along the nerve fibers. The model indicates a possibility for the existence of a mechanism of compression of the input wide frequency band signal that retains its energetic parameters (in a certain(More)

Acoustic analysis of the species-specific call of common rosefinch Carpodacus erythrinus was carried out. We compared calls of 12 individuals from the same habitat. The individual-specific elements were revealed in the calls. At the same time, species-specific elements were also recognized in all individuals. These elements compose the acoustic image of(More)
Neuronal activity of the medullary nuclei in response to acoustic stimuli was studied by electrophysiology. Neuronal activity was recorded from three nuclei: magnocellular, angular, and laminar. Both tonic and phasic neurons of all nuclei demonstrated a strict dependence of their discharge on temporal patterns of acoustic stimuli. The medullary nuclei(More)
An analysis of Russian and foreign literature data on the ways of developing acoustic signals in birds is presented. The physical analysis of acoustic signals is given for six species of birds: long-tailed skua (Stercorarius longicaudus Uicill), herring gull (Larus argentatus Pontopp.), sabine’s gull (Xema sabini sab.), curlew sandpiper (Calidris ferruginea(More)
Sonographic analysis of conspecific advertisement calls of yellow-breasted bunting (Emberiza aureola) was carried out. Calls of nine individuals living in the same range were compared. Particular elements responsible for individual differences were recognized in the calls. At the same time, the elements defining conspecific characters were recognized in all(More)

We analyzed the mechanism of alarm call generation in various bird species, species-specific calls in closely related species, and intraspecific differences in calls. Production of these signals proved to rely on common mechanism: variation of temporal indices within the frequency range limited by morphological structures of the vocal apparatus. These(More)
