Of wild species of ungulate, deer are the preferred prey family. In a study in the Italian Alps, the most common prey species of all was the European roe deer (Capreolus capreolus), which made up 32.2% of nest remains. The roe deer was also a prominent prey item in the French Pyrenees (14.9%) and Switzerland (14.6%), respectively. In several parts of the Scottish Highlands, red deer (Cervus elaphus) are eaten with some regularity, the maximum representation there being 22.3% of prey remains in the Northwest Highlands. In North America, several deer species, but mainly mule deer (Odocoileus hemionus) fawns, were significant in the diet in Washington (14.3%) and California (12.7%). Around the Himalayas, the small white-bellied musk deer (Moschus leucogaster) is reportedly a favorite prey item (though no quantitative analysis are known). In the near Arctic regions of Scandinavia, reindeer (Rangifer tarandus) of both semi-domestic and wild stock are fed on with some regularity; one study in northern Sweden found reindeer formed 11.4% of prey items. In the northernmost stretches of Alaska, golden eagles are more scarce than in equivalent areas of Scandinavia and only occasionally hunt wild reindeer. However, golden eagles were reportedly the most prolific predator of neonatal calves from the Porcupine caribou (Rangifer tarandus granti) herd of central Alaska. Partial moose (Alces alces) remains have been found at a nest in Sweden. Live fawns and carrion probably comprise most of the golden eagle's consumption of deer (certainly in larger-bodied species such as red deer). Among wild bovids, eagles are reportedly the main predator of Saiga antelope (Saiga tatarica) calves in Mongolia and are regularly reported to take chamois (Rupicapra rupicapra) and Alpine ibex (Capra ibex) calves in Europe. Mongolian gazelles (Procapra gutturosa) comprised about 15% of the remains found at a nest in Mongolia. Up to seven wild species of goat, five other wild species of sheep and at least two wild gazelle species are confirmed golden eagle prey. In North America, pronghorn (Antilocapra americana) are occasionally hunted.
