北红尾鸲在浙江清凉峰国家级自然保护区的繁殖记述

Breeding Ecology of Phoenicurus auroreus in Zhejiang Qingliangfeng National Nature Reserve

2015年和2016年的5_7月，在浙江清凉峰国家级自然保护区野外调查期间发现一处北红尾鸲Phoeni—curus auroreus巢址，并对其繁殖习性进行了观察。结果表明：北红尾鸲在本地为冬候鸟，但首次发现该种鸟类夏季在此繁殖；北红尾鸲的繁殖期为5月下旬至7月中旬，5月下旬开始营巢，持续10d左右，巢穴外径7．5cmx5．8cm、巢深3．2cm，巢材由苔藓、体羽、禾本科杂草茎等组成；6月中旬产卵，窝卵数为4—5枚（2015年产卵4枚、2016年产卵5枚），孵化期11—12d，巢内育雏14d。推测冬候鸟北红尾鸲在此繁殖可能与气候变化有关。

One nest of Phoenicurus auroreus was first found in Zhejiang Qingliangfeng National Nature Reserve and the breeding habits of P. auroreus were also addressed based on our field observation from May to July in 2015 and 2016. As a winter resident in Zhejiang province, its breeding behaviors in summer were first observed. The nest was built in late May and completed in early June. The nest （7.5 cm length x 5.8 cm width × 3.2 cm depth） was composed of the moss, feath- ers, stems of Gramineae and others. The eggs were laid in mid-June. Four and five eggs were found in 2015 and 2016, re- spectively. The hatching time was 11 - 12 days and the time of nestlings leaving the nest was 14 days. The breeding behav- iors of P. auroreus in summer in this reserve may be resulted from the climate change.
