  • The morning song of five garden birds in Hangzhou was recorded at a fixed site,and for certain individuals in spring.The records were then processed with a computerized analysis system,resulting in that 1)there was a certain time-sequence of beginning songs for the species sharing the same range:Turdus merula sang always first,and Parus major,Pycnonotus sinenesis,and Copsychus saularis sang in an order changing monthly;2)the principle frequency (PF) of songs of the species ranged between 2.4-4.1 kHz,and were significantly different between species except that between Copsychus saularis and Passer montanus.The PF difference offers some basic information for further studies on the competition for frequency domain in the bird community.

Characteristics of Time Sharing and Frequency Domain on the Morning Song of Garden Birds in Spring in Hangzhou

Abstract: The morning song of five garden birds in Hangzhou was recorded at a fixed site,and for certain individuals in spring.The records were then processed with a computerized analysis system,resulting in that 1)there was a certain time-sequence of beginning songs for the species sharing the same range:Turdus merula sang always first,and Parus major,Pycnonotus sinenesis,and Copsychus saularis sang in an order changing monthly;2)the principle frequency (PF) of songs of the species ranged between 2.4-4.1 kHz,and were significantly different between species except that between Copsychus saularis and Passer montanus.The PF difference offers some basic information for further studies on the competition for frequency domain in the bird community.
