In The Hobbit, The Lord of the Eagles admits to stealing sheep from men - albeit risky because they would fire at the eagles with their great yew bows. They also bring rabbits and hares to feed their dwarven guests. The thing is, regular sized eagles can take rabbits and sheep. The great eagles of middle-earth should have been able to kill and take off with much larger prey. I'd like to think that deer were their favored prey, along with any livestock they could get their talons on. Living off rodent, reptile, bird and fish seems ineffective if larger prey is available.
On the other hand, it would seem rather petty of the servants of Manwë to steal from the children of Illúvatar. (Far from the only inconsistency between The Hobbit and other works, I guess.) At least the noble steeds of the rohirrim should be off limits. Aewheros (talk) 15:08, November 23, 2014 (UTC)
