Birds activities at urban greenways in Bogor

Greenway is one of available habitats for birds in Bogor. Birds that occupied greenways are more susceptible to traffic noise disturbance because birds use acoustic signals to communicate. This research aims to identify noise levels and bird activities in four Bogor greenways with different traffic frequencies. Four greenways observed in this research were Jalan Ahmad Yani, Jalan Paledang, Jalan Semeru and Jalan Tentara Pelajar. Methods used in this research were measuring noise with sound level meter, and O'Donnell and Dilk's five-one minute observation on birds. The result showed that Jalan Semeru had the highest noise value. Foraging activities, singing, and perching had lower frequencies in the noisiest greenway, while breeding activities was never recorded.
