鸟类血浆皮质酮浓度通常在暴露于应激源（如捕获和处理）后约3分钟增加。当测量肾上腺反应的雏鸟在育雏与一个以上的雏鸟，标准化捕获协议，以平衡雏鸟之间的应激源，如果他们同时感知的存在和活动的研究人员作为一个应激源是后勤困难。我们的研究的目的是，以确定如果雏鸟黑腿Kittiwakes（里萨tridactyla）在两个安装一个皮质酮反应的育雏时，第一个雏鸟从巢中取出，或者，如果每个启动皮质酮反应，只有在它被处理的时候。我们从一个雏鸟的血液样品在3分钟内的初始干扰的巢，然后删除和采样的同胞10分钟后。对于年幼的雏鸟，我们发现在3分钟取样的雏鸟和在10分钟取样的兄弟雏鸟之间的皮质酮水平没有差异。相反，在初始巢干扰后10分钟取样的年长雏鸟的皮质酮水平高于3分钟内取样的雏鸟。在3分钟内捕获的雏鸟采样皮质酮升高时，暴露于长期的调查干扰附近的巢。我们的研究结果表明，这是必要的，以治疗初始干扰的巢开始的应激反应，为所有雏鸟在多雏鸟育雏时，处理年龄较大的雏鸟或雏鸟的年龄不详。此外，对于在密集的殖民地筑巢的物种，在一个巢的调查员的存在可能是一个应激源的雏鸟在相邻的巢。
Plasma corticosterone concentrations in birds often increase about 3 min after exposure to a Stressor such as capture and handling. When measuring adrenal responsiveness of nestlings in broods with more than one nestling, standardizing capture protocols to equalize the Stressor among nestlings if they simultaneously perceive the presence and activity of a researcher as a Stressor is logistically difficult. The objective of our study was to determine if nestling Black-legged Kittiwakes {Rissa tridactyla) in broods of two mount a corticosterone response when the first nestling is removed from the nest or, alternatively, if each initiates a corticosterone response only at the time it is handled. We obtained blood samples from one nestling within 3 min of initial disturbance of the nest, and then removed and sampled its sibling 10 min later. For younger nestlings, we found no difference in corticosterone levels between those sampled at 3 min and their sibling sampled at 10 min. In contrast, older nestlings sampled at 10 min after initial nest disturbance had elevated corticosterone levels compared to those sampled within 3 min. In addition, nestlings sampled within 3 min of capture had elevated corticosterone when exposed to protracted periods of investigator disturbance at nearby nests. Our results suggest that it is necessary to treat initial disturbance of the nest as the onset of the stress response for all nestlings in multi-nestling broods when handling older nestlings or nestlings of unknown age. In addition, for species that nest in dense colonies, the presence of an investigator at one nest may be a Stressor for nestlings in adjacent nests.
