NONTYPICAL is right on, as usual. I've seen eagles kill both deer and antelope. Eagles are big-time athletes. They ususally fly down and hit an ungulate right at the base of the neck. If there's a pair of goldens, they will take turns gaining altitude and dropping down to "hammer" a yearling or fawn. Eventually, the eagles will weaken or blind the deer/antelope by raking their talons. Then the deer/antelope is done and the eagle will use its beak to reach in and severe the spinal cord.
I've even watched coyotes and foxes that follow eagles looking for a meal. After an eagle makes a kill, the canids will hang around, fight and get something to eat.
I'd say this is all part of what I call the "hierarchy of predation" and is one of the prime reasons we have fewer deer (and rabbits) than there were 40-50 years ago. There are a LOT more predators of various sorts and sizes. Additionally, with more hawks, owls and eagles, they eat more of the small rodents and rabbits, which forces the coyotes and lions to eat more deer.
