Ages of breeding golden eagles at territories within 30 km of the Altamont windfarm.

The asterisk indicates that the calculation included two individuals of uncertain age and therefore gave the maximum possible representation of subadults for that year. Note that yearly variation in the number of aged eagles reflects differences in sampling effort rather than population.

星号（asterisk）表示本次计算纳入了2只年龄不明的个体，因此该结果为当年亚成体（subadults）的最大可能占比。请注意，经年龄鉴定的鹰类个体数量存在年度波动，该波动实则反映的是采样力度的差异，而非种群实际规模的变化。
