| 2017和2018年每年的4至8月在甘肃莲花山国家级自然保护区，对人工巢箱中黑冠山雀（Periparus rubidiventris）的繁殖生态进行了研究。共悬挂100个巢箱，两年共计招引到15巢黑冠山雀。此外，还记录到4个自然巢，分别位于干枯的糙皮桦（Betula utilise）树洞（1巢）、土坡的缝隙（1巢）和路边水泥护坡的出水管中（2巢）。黑冠山雀雌雄亲鸟共同筑巢，巢内壁为兽毛夹杂少量绒羽，外壁为草茎须根和苔藓。5月中下旬为黑冠山雀的产卵高峰期，清晨产卵，日产1枚，产下最后1枚卵后开始孵卵。平均窝卵数为6枚（4 ~ 7 枚，n = 15），平均卵重（1.12 ± 0.02）g，卵长径（15.30 ± 0.10）mm，卵短径（12.09 ± 0.11）mm（n = 86）。孵卵由雌鸟承担，孵卵期为15 d（14 ~ 16 d，n = 5）。产卵期，雌鸟离巢时有用巢材盖卵的行为，开始孵卵后则不再盖卵。双亲共同育雏，育雏期为16 d和17 d（n = 2）。所记录的18巢黑冠山雀的繁殖成功率为83.3%，人工巢箱（15巢）中繁殖成功率为86.7%，巢捕食者主要为鼠类。 |

| We studied the breeding ecology of the Rufous-vented Tit (Periparus rubidiventris) at Lianhuashan Nature Reserve, Gansu Province, from April to August in 2017-2018. A total of 100 nest-boxes were hung while 15 were used by Rufous-vented Tits in two years (Fig. 1). We also found four natural nests, which located in a hole of a dry birch (Betula utilize) (Fig. 1), crevice in walls and outlet pipes in cement revetment by the roadside. From mid-April, we started to check the nest-boxes once a week. When mosses or other fillings were found in the nest-boxes, we checked them more frequently (normally each day) and made notes of their laying dates, hatch dates, clutch sizes and numbers of nestlings. The data were calculated by SPSS 21.0 for Windows, and were expressed by Mean ± SE. Both sexes participated in the nest-building work. The outer part of the nest was constructed with grass stems, fibrous roots and mosses while the inner part being constructed with animal hairs and a few of small feathers. The peak of laying date was around of mid-to-late May, with one egg laid per day and an average clutch size of 6 eggs (4﹣7, n = 15). Females covered the egg with the nest materials before incubating. The average weight of the eggs was 1.12 ± 0.02 g, with the size of 15.30 ± 0.10 mm × 12.09 ± 0.11 mm (n = 86). Females began to incubate after the last egg was laid and the incubation period lasted around 15 d (14﹣16 d, n = 5). Both sexes fed the nestlings, we also measured the nestlings of 13 nests (Fig. 2). In this study, the breeding success rate was 83.3% for all nests, and 86.7% for the nest-boxes, with the main predators of mice. |
