对于蓝山雀的巢穴建设，但不是大山雀，第一个鸡蛋日期（美联储）结果蓝山雀和山雀的巢箱中巢材的利用受当时的气候条件影响，而温度对巢的整体质量和部分组成部分的质量有显著的影响，对巢材的利用受当时的气候条件影响的假说进行验证。在2008年和2009年的繁殖季节，在英格兰林肯郡的一个地点。巢被解剖成其组成部分，然后weight.Results逐步判别分析表明，草，羽毛和树皮的质量显着影响的物种（所有较高的蓝山雀）和年显着影响的羊毛和灰尘的质量在巢中。方差分析表明，巢的总质量没有显着影响的建设年或物种。相比之下，物种，而不是一年，显着影响群众的动物和植物来源的材料在巢。在蓝山雀巢中，2008年FED与动物源性材料质量之间存在显著相关性，但2009年与植物源性材料之间存在显著相关性。有显着的相关性，平均气温记录在7天的FED和质量的巢和它们的植物来源的材料。FED和巢组件之间没有显着的相关性，观察大山雀。结论巢建设是潜在的各种环境因素，这可能会影响巢功能。更好地了解鸟巢的变化如何影响其功能，可以更好地评估气候变化如何影响鸟类的生殖性能。
Capsule For nest construction by Blue Tits, but not Great Tits, first-egg date (FED) and air temperature significantly affected the mass of the nest as a whole and some of its component parts.Aims To test the hypothesis that use of nest materials is influenced by prevailing climatic conditions during nest construction.Methods Nests used in the study were built by Blue Tits Cyanistes caeruleus and Great Tits Parus major in nestboxes at a site in Lincolnshire, England during the 2008 and 2009 breeding seasons. Nests were dissected into their component parts and then weighed.Results Stepwise discriminant analysis showed that the masses of grasses, feathers and bark were significantly affected by species (all higher in Blue Tits) and year significantly affected the mass of wool and dust in the nests. ANOVA showed that total mass of the nest was not significantly affected by year of construction or species. By contrast, species, but not year, did significantly influence the masses of animal-and plant-derived materials in the nest. In Blue Tit nests there were significant correlations between FED and the mass of animal-derived material in 2008, but with plant-derived material in 2009. There were significant correlations between mean air temperature recorded during the seven days up to FED and the mass of the nests and their plant-derived materials. No significant correlations were observed between FED and nest components for Great Tits.Conclusion Nest construction is potentially affected by a variety of environmental factors, which may impact upon how nests function. A better understanding of how nest variability affects its function may allow better assessment of how climate change may impact upon the reproductive performance of birds.
