Abstract

The Chinese Bulbul, Pycnonotus sinensis check for this species in other resources , is one of the most abundant and widely distributed birds of south China, settling even in dense urban areas. From March-July 2012, we surveyed the Chinese Bulbul in the urban environment of Hangzhou, China, to gain a clearer perspective on their breeding ecology. Totally, 117 nests were found, mainly on the trees of Osmanthus fragrans check for this species in other resources (84.6%, n=117) in residential areas, street tree strips, and green belt. Our results include several noteworthy observations: nest height from the ground was 3.16±0.91m (n=117); egg-laying begins in early April with peak times from April 11−25; and the nesting period was 11.85±1.12 days (n=47). In terms of fertility and reproduction, we also observed that the average incubation period was 11.34±1.12 days (n=32); average clutch size was 3.37±0.48 eggs (n=103); hatching success 68.3%, fledging rate 52.1%, and the total breeding success 35.58% (n=117). The main causes of breeding failure included egg and fledgling predation, as well as human disturbance.
