Nutrition during the time spent at the nest is critical for the development of the body condition in altricial birds, including nestling blue tits (Cyanistes caeruleus). Trophic conditions tend to be variable in time and space, which should influence the physiological condition of growing birds. In this paper, we consider haemoglobin concentration as a general indicator of chick physiological condition. Its variation is both consistent within broods and indicative/prognostic of survival from the moment of hatching to fledging. We show that haemoglobin concentration of nestling blue tits is on average higher in years and habitats characterised by rich abundance of caterpillars than under poor caterpillar availability. Haemoglobin seems to quite exactly reflect even relatively subtle differences in trophic conditions.
对于晚成鸟，包括雏鸟蓝山雀（Cyanistes caeruleus）来说，在巢中度过的这段时间的营养对其身体状况的发育至关重要。营养条件在时间和空间上往往是可变的，这会影响正在生长的鸟类的生理状况。在本文中，我们将血红蛋白浓度视为雏鸟生理状况的一个总体指标。其变化在一窝雏鸟中是一致的，并且从孵化到 fledging 的整个过程中都能指示/预测生存情况。我们发现，在以丰富的毛虫数量为特征的年份和栖息地中，雏鸟蓝山雀的血红蛋白浓度平均高于毛虫数量少的情况。血红蛋白似乎能相当准确地反映营养条件中甚至相对细微的差异。
