Distribution

The golden eagle subspecies A. c. chrysaetos is distributed in Europe and Siberia. The subspecies A. c. homeyeri is distributed in North Africa, Mediterranean region, Middle East, Arabia, Iran and Uzbekistan. The subspecies A. c. daphanea is distributed in Central Asia, Central China and north Indian subcontinent. The golden eagle subspecies A. c. kamtschatica is distributed in Siberia and East Russia.

Status and conservation

The golden eagle global population is estimated to number more than 170,000 birds. These species have an extremely large range and are considered least vulnerable. Poisoning, persecution, trapping, loss of habitat, use of certain pesticides, electrocution from power lines, collision with the wind turbines and long term changes in food supply are the major threats to the survival of these eagle species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these eagle species and has listed them as of "Least Concern".
