Мисливські водоплавні птахи водосховища "Відсічне" (Житомирська область)

When carrying out any reconstruction measures related to the use of natural resources, it is necessary to pay attention to the state of biodiversity, in this case, on waterfowl game birds. Vidsichne Water Reservoir is the main object of water supply to the city of Zhytomyr. Like other reservoirs, this one periodically needs to be cleaned of silting, overgrown, etc. However, a certain structure of the plant and animal world, which needs protection, has formed in this reservoir. Waterfowl game birds accounting was carried out from coastlines and from the boat using the method of a complete list of individuals. The analysis of the number of birds was carried considering the relative rating scale proposed by A. P Kuziakin. The main source of water resources of Vidsichne Water Reservoir is the Teteriv River together with its tributaries – the Gnilopyat River, the Guiva River and others. The catchment area of the reservoir is approximately 1780 km2. The representatives of Goose Birds are characterized by the largest variety amounting to 17 species. We found 5 species among the nesting birds and 10 species of flying birds here. The Scalloped take the second place numbering 4 species, of which all are nesting. The Gruiformes take the third place amounting to 2 species, which are also nesting. And, finally, only 1 species was registered among the Gagaropedic and the Pelican species, which we recorded in the flying period. According to a relative number among waterfowl game birds, rare species predominate amounting to 11, then ordinary species amounting to 8. Only 3 species are numerous. The Pelican species of birds are observed periodically; therefore we refer them to species with an indefinite number. In spring-migration period, there were 15 species, of which Mallard dominates (53.4 %). The Eurasian wigeon takes the second place (6.7 %), then the common pochard and the Eurasian coot are (2.7 2.0 %). In the breeding period, mallard continues to dominate (56.1 %), the Eurasian coot and the common moorhen co-dominate (19.4 % and 10.2 %). Watercourse leakages where the outflow vegetation grows steadily are characterized by the largest variety and number. Such conditions are optimal for nesting birds. The red-necked grebe and the Baikal teal can be singly seen here in the breeding period. In the autumn-migration period, 15 species of waterfowl birds were identified. Mallard (48.0 %) continues to dominate, however, unlike the breeding period, the common pochard and the Eurasian wigeon (6.9 %) co-dominate. On the flights, the northern pintail, the little grebe, the Baikal teal, the black-throated loon, and other species appear. To conclude, Vidsichne Water Reservoir is considered to be promising for waterfowl game bird hunting. However, it is important to carry out a set of biotechnical measures outlined in the work.
