When he was found, the eagle was on the ground and unable to fly and the volunteers took him to Dr. Suzanne Colbert at the Princevalle Pet Hospital in Gilroy, wildlife center officials said.
Colbert x-rayed the bird's large wings, but found no fractures or dislocations. She did find a wound on the eagle's left wrist that was causing the wing to droop, and suspects the eagle may have been suffering from head trauma.
The damaged wing was bandaged and Colbert gave the eagle fluids and medication and sent him back to the Wildlife Education and Rehabilitation Center to recuperate.
The bird is underweight at seven pounds - he should way about 10 pounds and has a wing-span of over 6 feet - but center officials are optimistic that he'll recover.
He will return to Colbert for a checkup on March 7 at 11 a.m.
