Reference to the Golden Eagle has brought additional interest to The Jhon Collector Mysteries. Mention of personal experience has resulted in, conservatively, a deluge of communications from people wanting to know more.
You ask, I do:
Golden eagles weigh between 6-15 pounds (3-7 kg). The weight varies depending on latitude and gender.
Generally, males weigh approximately 25% less than females from the same area. The average weight of a female golden eagle is 10-14 pounds; however there exists great variation depending on where an eagle is from. This difference in size between males and females is referred to as reverse sexual dimorphism.
