Dietary biology of the golden eagle eagle nests. The first record of a golden eagle eating eggs was recorded when a golden eagle was observed consuming Canada goose ("Branta canadensis") eggs in eastern Idaho. After galliforms, the next most significant group of prey among birds is the corvid family, making up 4.1% of the diet from around the range. Most prevalent among these are magpies and the large-bodied "Corvus" (crow and raven) genus. On Santa Rosa and Santa Cruz Islands in California, common raven became the most common prey species after feral pigs were eradicated from the latter, making up 24% of a 454 sample size
