Abstract: Road traffic noise forces wild birds to avoid the source of interference and to leave their original habitat. Understanding how the retreat behavior of birds quantitatively responds to the road traffic noise will provide theoretical basis for constructing the roads ecologically. By setting up retreat space in the laboratory and implementing a variable controlling approach to eliminate interference factors, we simulated road traffic noise in the wild with noise replay, examined its effects on retreat behavior of thrushes. Then, we analyzed the quantitative relationship between the distribution of thrushes in the retreat space and the sound pressure levels of noise. The results showed that: (1) Thrushes’ retreat behavior was affected by the road traffic noise. (2) There was no significant difference in the effect of traffic noise on the retreat rate between male and female individuals. (3) The relationship between thrush retreat rates (y) of thrushes and the sound pressure levels of noise (x) was well fitted as follows: y=0.071x-4.452.
