  • To fill the gap in breeding biology information about the Red-Whiskered Bulbul (Pycnonotus jocosus), in 2013, we studied the breeding biology of this species in Xishuangbanna, southwest China. The breeding began from February and continued until early August. The breeding strategy of P. jocosus was more flexible and their nests were only built in cultivated landscapes, whereas, no nest building in native tropical rain forest was found. Small open cup nests were built on 50 different plant species, and at heights ranging from 2.1±0.6 m above the ground (n=102). The mean clutch size was 2.53±0.51 eggs (n=40) and the mean egg mass was 2.81±0.25 g (n=60). The average incubation period was 11.1±0.5 days (n=14), and the average nestling period was 11.0±0.8 days (n=31). The overall nest success was 34.22%.The hatching and fledging showed either asynchrony or synchrony. Invertebrate food decreased with nestling age, whereas, plant food increased with nestling age. Moreover, distinct parental roles of the parents in nestling period were found. Compared with other passerine species, P. jocosus spent less time in incubating (58%). The clutch size, incubation and nestling period of the P. jocosus in southwest China were different from those of the P. jocosus in India.

Abstract: To fill the gap in breeding biology information about the Red-Whiskered Bulbul (Pycnonotus jocosus), in 2013, we studied the breeding biology of this species in Xishuangbanna, southwest China. The breeding began from February and continued until early August. The breeding strategy of P. jocosus was more flexible and their nests were only built in cultivated landscapes, whereas, no nest building in native tropical rain forest was found. Small open cup nests were built on 50 different plant species, and at heights ranging from 2.1±0.6 m above the ground (n=102). The mean clutch size was 2.53±0.51 eggs (n=40) and the mean egg mass was 2.81±0.25 g (n=60). The average incubation period was 11.1±0.5 days (n=14), and the average nestling period was 11.0±0.8 days (n=31). The overall nest success was 34.22%.The hatching and fledging showed either asynchrony or synchrony. Invertebrate food decreased with nestling age, whereas, plant food increased with nestling age.
