This study explored the relationship between soundscape and birdsong and the factors that influence perceived birdsongs in urban parks. Three soundscape parameters were conceived: the soundscape harmonious degree (SHD), the number of perceived birdsongs (NPB) and the accuracy of perceived birdsongs (APB). These were collected to find an effect of geophony, biophony and anthrophony on perceived birdsongs. Results indicate that there is a positive correlation between SHD of geophony, biophony and birdsongs, and the sound frequency is an important factor for NPB in the urban parks. In addition, this study found group birdsong play a key role in APB in urban parks.
