The blue tit (Cyanistes caeruleus) is one of a few known passerine birds that incorporate fresh fragments of aromatic plants in their nest during the nesting period. In this study, we experimentally tested whether aromatic plants in blue tit nests affect physiological condition of nestlings as indicated by hemoglobin and glucose in the blood. Nestlings in nests supplemented with fresh, aromatic plants had elevated blood hemoglobin, and therefore improved physiological condition, as compared with control nestlings. There was no difference between nestlings in two contrasting habitats (urban parkland and forest). Although mean levels of blood glucose did not differ between treatment and control nestlings, the blood of forest nestlings contained more glucose than the blood of parkland nestlings, which indicates poorer health for forest nestlings. In general, knowledge of the effects of incorporating fresh green, aromatic plant material into avian nests on physiological condition of nestlings is still fragmentary and more experimental studies are needed. The blue tit is one of a few known passerine birds that incorporate fresh fragments of aromatic plants in their nest during the nesting period. Little is known about the impact of this material on nestling body condition, and there is a need to understand this behavior and its effects. We tested whether nestlings in nests supplemented with fresh, aromatic plants improved their physiological condition in comparison with control nestlings. The experiment showed that nestlings from supplemented nests improved their physiological condition by exhibiting elevated hemoglobin.

将新鲜芳香植物实验添加到蓝山雀 (Cyanistes caeruleus) 巢穴中对雏鸟生理状况的影响

蓝山雀(Cyanistes caeruleus)是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。在这项研究中,我们通过实验测试了蓝山雀巢中的芳香植物是否会影响雏鸟的生理状况,如血液中的血红蛋白和葡萄糖所示。与对照雏鸟相比,添加了新鲜芳香植物的鸟巢中的雏鸟具有升高的血红蛋白,因此改善了生理状况。两个对比鲜明的栖息地(城市公园和森林)中的雏鸟没有区别。尽管治疗和对照雏鸟的平均血糖水平没有差异,但森林雏鸟的血液比公园雏鸟的血液含有更多的葡萄糖,这表明森林雏鸟的健康状况较差。总的来说,关于将新鲜的绿色芳香植物材料掺入鸟巢对雏鸟生理状况的影响的知识仍然是零碎的,需要更多的实验研究。蓝山雀是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。关于这种材料对雏鸟身体状况的影响知之甚少,有必要了解这种行为及其影响。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。芳香植物材料进入鸟巢对雏鸟生理状况的影响仍是零碎的,需要更多的实验研究。蓝山雀是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。关于这种材料对雏鸟身体状况的影响知之甚少,有必要了解这种行为及其影响。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。芳香植物材料进入鸟巢对雏鸟生理状况的影响仍是零碎的,需要更多的实验研究。蓝山雀是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。关于这种材料对雏鸟身体状况的影响知之甚少,有必要了解这种行为及其影响。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。蓝山雀是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。关于这种材料对雏鸟身体状况的影响知之甚少,有必要了解这种行为及其影响。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。蓝山雀是少数已知的雀类鸟类之一,它们在筑巢期间在巢中加入新鲜的芳香植物碎片。关于这种材料对雏鸟身体状况的影响知之甚少,有必要了解这种行为及其影响。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。我们测试了在补充了新鲜芳香植物的巢中的雏鸟与对照雏鸟相比是否改善了它们的生理状况。实验表明,来自补充巢的雏鸟表现出升高的血红蛋白,从而改善了它们的生理状况。
