鸟类被假定有一个恒定的成年死亡率，其中一个恒定的比例，一个队列死亡，在每个年龄段。报告的许多物种的年平均死亡率将导致极长的潜在寿命，似乎更合理的假设是鸟类死亡率取决于年龄。几种鸟类的死亡率和存活率的数据进行了分析，并讨论了年龄相关死亡率的替代模型。
Birds have been assumed to have a constant adult mortality rate in which a constant fraction of a cohort dies in each age interval. Average annual mortality rates reported for many species would result in exceedingly long potential life spans, and it seems more reasonable to assume that avian mortality is age dependent. Data on the mortality and survivorship of several species of birds are analyzed and alternative models of age-dependent mortality are discussed.
