On systematization and documentation of bioacoustic materials

The collection of original field bird sound recordings made by Prof. B.N. V eprintsev in 1960-1975 is systematized; the audiomaterials are documented t o conform with the international standards. The materials are used in study ing taxonomy, phylogeny, comparative ethology, microevolution, faunistics, inventory, and identification of birds by sound in nature. The development of a catalog system and a computerized database provide a reliable and quic k search for the necessary material in the collection. The marking of origi nal field tapes for species cuts, verification of identifying species and m ain indertifying sounds, and the description of the sound background result in the minimization of probable errors, when using the collection material s. The more accurate specification of dates and localities of recordings, s afekeeping of the author's comments and introduction of additional informat ion make the materials more valuable for scientific research. The technical data given permit one to assess the restrictions related to the equipment and materials used.
