Identification of semiaquatic avifauna species in shallow waters of the Don River delta using an autonomous remote-controlled midget floating craft

Abstract

A survey method for identifying avifauna in shallow areas of the Don River delta has been developed and tested using a prototype of an autonomous remote-controlled and self-propelled floating craft equipped with technical means for optical-visual observation and video filming (hereafter referred as the complex). The complex is remote-controlled by an operator. The methodology of the work included designing the complex and testing it in open water bodies, reconnaissance of the shallow water bodies in the Don River delta where the complex might navigate, the approbation of the panoramic video recording of birds, and processing of the recorded video for identification of the species. The complex is able to reliably collect visual information on the move as well as being stationed at points for bird observation. Thanks to the test missions of the complex, the selected shallow areas of the Don River delta were explored for the first time and reviewed by panoramic video recording. The 16 birds were captured in the footage, and 7 out of them were reliably identified. The panoramic video records can be also used for educational purposes. The developed complex has a relatively low manufacturing cost and can be assembled in a university lab too.
