Abstract:Bird song is an important behavior in birds, with great evolutionary and ecological implications. It is one of the best effective ways for communication among individuals within the bird communities. This has an significant relationships between bird song and individual intrinsic factors (body size, sex ratio). To examine the relationship between the singing behavior of varied tits and body size or sex ratio, we recorded the songs of varied tits (Parus varius varius) between March and June in 2014-2015 at Xianrendong Nature Reserve, Liaoning province. The body sizes of varied tits were measured and sex ratio was calculated based on poverserved, we found: (1) there was positive relationship between integrated morphological measurement and maximum frequency of bird song; (2) there was positive relationship between sex ratio and duration of verse of bird song. This study rich small birds body size relationships with singing, and the relationship between the song and offspring sex ratio at nest.
