BIRD SPECIES DIVERSITY IN THE VILLAGE UMBA IN WINTER
286 KB
The avifauna of the urban settlement of Umba (the Village Umba) in winter was compared with that one in the previous years based on the results of the earlier research. There was an attempt to reveal the connection between the composition and number and climatic conditions (temperature). A routing method was the main method applied in the research. The species composition of avifauna of the Umba Village in winter period was represented by 11 species. When comparing, a relative constancy of species composition in that period was observed. Fluctuations in the number of the certain types of birds in different years of observations were noted also. In particular, according to the observations, in the recent years, the number of mallard duck, blue rock pigeon and bullfinch was increasing, that could be connected with the expansion of their food supply. The reduction in number of magpies, raven, gray crow, domestics parrow and great titmouse was recorded. The number of a hazel grouse, willow tit and motley woodpecker remained to be relatively permanent. The statistical analysis of the results showed that the number of some bird species in the Umba Village was dependent on the air temperature changes.
