Patterns of nest attendance in birds result from complex behaviours and influence the success of reproductive events. Incubation behaviours vary based on individual body condition, energy requirements and environmental factors. We assessed nest attendance patterns in Cinnamon Teal Spatula cyanoptera breeding in the San Luis Valley of Colorado in 2016–2017 using trail and video cameras to observe behaviours throughout incubation. We evaluated the effect of temporal, life‐history and environmental covariates on the frequency and duration of incubation recesses as well as the incubation constancy. There was considerable model uncertainty among the models used to evaluate recess frequency. Recess duration varied according to the interaction between nest age and a quadratic effect of time of day, with hens on older nests taking longer recesses in the afternoon and hens on nests earlier in incubation taking longer recesses in the morning and evening. Incubation constancy decreased with higher ambient temperatures in the study area. This study provides evidence that Cinnamon Teal modify their behaviour during incubation according to the age of the nest and the time of day. These results improve our knowledge of Cinnamon Teal breeding ecology and shed light on the behaviours that fast‐lived species may use to cope with environmental factors during nesting.

影响肉桂蓝绿色燕窝出勤方式的因素

鸟巢中的出勤方式是由于复杂的行为造成的，并影响生殖活动的成功。孵化行为因个人身体状况，能量需求和环境因素而异。我们评估了蓝绿色小铲蓝nest中的出勤模式2016-2017年在科罗拉多州的圣路易斯山谷进行了繁殖，并使用跟踪摄像机和摄像头观察了整个孵化过程中的行为。我们评估了时间，生活史和环境协变量对孵化期的频率和持续时间以及孵化稳定性的影响。在用于评估凹陷频率的模型中，模型存在很大的不确定性。隐窝的持续时间根据巢龄和一天中时间的二次影响之间的相互作用而变化，老巢上的母鸡在下午需要较长的凹处，孵化较早的母鸡在早晨和晚上则需要较长的凹处。随着研究区域环境温度的升高，孵化常数降低。这项研究提供了证据，表明肉桂青色鸭在孵化过程中会根据巢的年龄和一天中的时间改变其行为。这些结果提高了我们对肉桂蓝绿色繁殖生态学的了解，并阐明了快活物种在筑巢过程中可能用来应对环境因素的行为。
