Некоторые особенности привлечения птиц-дуплогнездников в условиях Закарпатья

Abstract

Passer montanus L. and Sturnus vulgaris L. proved to be the only Inhabitants of 795 artificial nesting places in the oak-groves of the investigated region, the overwhelming majority of nesting places (738) being occupied by Passer montanus L. Such phenomenon is undesirable especially in the lotuses of Ocheria &Spar L. repro-duction because Passer montanus L. do not kill this parasite and besides, they prevent from nesting of other small hollow-nesting birds. Possible reason. of mass settlement of artificial nestings with Passer montanus L. a group hanging of n:ests, is not expedient in the insular forests of Transcarpathia.
