The contribution of ungulates to the diet of golden eagles has long been the most controversial and debated aspect of the species' whole biology. In total, deer comprise about 4.97% of all golden eagle food, bovids about 4.92%, pigs about 0.71% and pronghorns less than that. [10]
A fully-grown golden eagle requires about 230 to 250 g (8.1 to 8.8 oz) of food per day but in the life of most eagles there are cycles of feast and famine, and eagles have been known to go without food for up to a week and then gorge on up to 900 g (2.0 lb) at one sitting.

When salmon and trout are dying in winter after their summer spawning, feeding groups of Steller's sea eagles may mix with smaller golden eagles (Aquila chrysaetos) and white-tailed eagles to exploit this food source. This area is the only one in the golden eagle's nearly circumpolar range where they are extensively dependent on fish for prey. [61]

These large acciptrids may supplement their diets with aquatic animals other than fish, especially sea eagles , which also hunt large numbers of water birds and are expert ...
While the mean prey body mass relative to the eagle's weight is probably similar between the two species, an estimated 15% of golden eagle prey will weigh over 5 kg (11 lb). [7] [102] [103] [104] In its very extensive range, the golden eagle's distribution includes nearly all areas occupied by breeding eastern imperial eagles. Furthermore ...
Sumatra is one of the richest islands in Indonesia for animals. Its bird total species is second only to New Guinea. This great wealth is due to the large size of Sumatra, its diversity of habitat and also its past link with the Asian mainland.
