THE USE OF ARTIFICIAL NESTING SITES BY ANIMALS IN THE SOUTHERN PRE-BAIKAL REGION
The article discusses the use of artificial nesting sites by vertebrates and invertebrates in the Southern Baikal region. Characteristics of the population of the hollows as a whole and, depending on its size, are given. In total, during the observation, the artificial nesting sites were used for breeding by seven species of birds, two species of mammals and four species of representatives of real wasps. The proportion of the wasp inhabited ones (genera Vespa L., 1758, Vespula Thomson, 1869, and Dolichovespula Rohwer, 1916) was 26.2% of the total number of the artificial nests. As for birds, most of the hollows were inhabited by Coal tits Parus ater (L., 1758) (8.4%). The Asian chipmunk Tamias sibiricus (Laxmann, 1769), a representative of the theriofauna, occupied 6% of the artificial nesting sites. The proportion of the nests used by the Daurian redstart Phoenicurus auroreus (P., 1776) was slightly more than 1%. In less than 1% of cases, the hollows were used for breeding by the common redstart Phoenicurus phoenicurus (L., 1758), great tit Parus major (L., 1758), wryneck Jynx torquilla (L., 1758), swinhoes Robin nightingale Luscinia sibilans (Swinhoe, 1863), taiga flycatcher Ficedula albicilla (P., 1811) and the flying squirrel Pteromys volans (L., 1758). During the observation period, there were no direct conflicts for habitat in the artificial nests. Cases of displacement of one species by another from a hollow and predation by mammals were isolated.
