The following story was shared with us by Tri-State Bird Rescue in Delaware.
A concerned citizen reported this great horned owl hopping along a fence line but unable to fly; it appeared to have an injured wing.
Once transported to us for care, radiographs revealed that the raptor had a fracture in an ulna, one of the wing bones. This required pinning by our wildlife veterinarian. The owl was also neurologic, quiet, and had a parasite infestation.
He was gavaged with EmerAid Intensive Care Carnivore for a day prior to switching to prey items. With proper rehabilitation, the large owl fully recovered and was released back to the wild.
