Influence of radar radiation on breeding biology of tits (Parus sp.).

The aim of the present study is to observe the influence of long-term exposure to radar radiation on breeding biology of tits (Parus sp.), living and building nests around a military radar station, emitting pulse-modulated microwave radiation of 1,200-3,000 MHz. Two series of 36 nest-boxes each were located on the radar station area.
