It's too early to tell whether Phoenix will be able to fly in the wild. Rehabilitation will take at least a year and his feathers won't fully molt until mid-2013.
"We are fairly confident, but there could be follicle damage we do not know about that would prevent feathers from coming in," Erickson said.
The nonprofit center, which treats about 1,800 animals a year, is accepting financial and food donations to offset the cost of caring for the golden eagle.
"He is doing well and we are very positive about his outcome right now," said Erickson. "(But) these types of things can turn at any moment."
In her 12 years of wildlife rehabilitation, Erickson said, the eagle's story is among a few cases she considers "nothing short of a miracle."
