资源简介：
This data set includes data from female white-tailed eagles aged 14 – 23 and male white-tailed eagles aged 19 – 23 years to examine breeding productivity.
ID = Individual identity
Territory = individual code for breeding territory
Year = year of breeding attempt
Origin = Origin of individual
Origin categories: R1 = release phase 1, R2 = release phase 2, W= wild bred
Sex = Male / Female
Last_age = age at individuals last breeding attempt NB. Many were still alive and breeding while monitoring was on going. Therefore year of last recorded breeding attempt also given (Last_year).
Age = age at breeding attempt
Fledged = 0/1/2 the number of chicks fledged
本数据集涵盖14至23岁雌性白尾海雕、19至23岁雄性白尾海雕的相关数据，用于探究其繁殖生产力。
ID：个体标识（Individual identity）
Territory：繁殖领地个体编码
Year：繁殖尝试年份
Origin：个体来源，分类标准为：R1=第一阶段放归个体，R2=第二阶段放归个体，W=野生繁育个体
Sex：雄性/雌性
Last_age：个体最后一次繁殖尝试时的年龄。注：监测期间多数个体仍存活并参与繁殖，因此同时记录了其最后一次被记录到的繁殖尝试年份（Last_year）。
Age：繁殖尝试时的年龄
Fledged：出飞雏鸟数量，取值为0/1/2
