Vd. Ilichev et al., ECOLOGICAL AND TECHNOGENOUS FACTORS OF NOISE-POLLUTION OF NATURAL HABITATS OF BIRDS, Russian journal of ecology, 26(5), 1995, pp. 345-348
Noise pollution caused by transport was compared with that of natural
origin at five experimental plots in Central Russia and the Southern U
ral Region by means of standard and modified methods. Bird songs were
registered as an ecological factor. A priority increment of technogeno
us factors was revealed for the territories around motor, aircraft, an
d railroad sources. It was shown with reference to the chaffinch that
bird songs are deformed under conditions of technogenous noise polluti
on.
