The 15-pound eagle was found in 2005 scrounging for food and slowly starving to death at a landfill in Alaska. Most of her curved upper beak had been shot away, leaving her tongue and sinuses exposed. She could not clutch or tear at food.
Beauty was taken to a bird recovery center in Anchorage, where she was hand-fed for two years while her caretakers waited in vain for a new beak to grow.
"They had exhausted their resources and she would likely be euthanized," Cantwell said.

JB-Weld or PC-7 Epoxy will hold that artificial beak in place forever (or at least until the bird is long dead).
“...while her caretakers waited in vain for a new beak to grow”
You might as well wait around for your amputated foot to grow back. What’s up with these people?
Ah yes. Beauty and the Beak.
Why not feed it corn for a while, then roast it?
