摘　　要：鸟类在筑巢期投入能量的多少会影响其繁殖成效,巢材组成的差异也会影响其最终繁殖产出。本文以大山雀(Parus major)为研究对象,通过探究巢重及巢材组成对其繁殖的影响,以揭示筑巢投入和巢材对繁殖产出的影响。对2015年收集到的35巢进行了分析。结果表明:巢材总重与出飞数、出飞成功率及繁殖成功率呈极显著的负相关;羽毛重及其所占总重的比例与窝卵数、出雏数及出飞数呈显著的正相关,与产首枚卵的日期呈显著的负相关;植物茎重及其所占总重的比例与窝卵数及出雏数呈显著的正相关。本研究表明,大山雀亲鸟筑巢消耗的能量越多,子代出飞情况反而越差;同时,巢内保温性和支撑性巢材越多,繁殖产出越大。Nest construction effort may affect the reproduction of parent birds and their subse- quent capacity to care for offspring. The difference of nest material components may also affect bird reproduction. This study examined the influence of nest construction cost and nest material components on breeding performance of Parus major by analyzing 35 nests. The results showed that total nest mass was negatively correlated with the number of fledglings, fledging success rate and breeding success rate. The mass of feather and its proportional contribution to the total nest mass were positively correlated with clutch size, the number of hatchlings, and fl negatively correlated with first-egg date related to the mass of plant stem and i edglings, but . Clutch size and the number of hatchlings were positively ts proportional contribution to the nest mass. The results suggest that there would be fewer fledglings with less fledging success and breeding success from the nest that costs more energy from parents during construction. In contrast, the nest with more insulation and supporting materials will ensure better breeding performance.
