National Aviary veterinarian Pilar Fish developed a novel method of restraining and examining birds without anesthesia, eliminating a serious risk for the birds. Under Dr. Fish's method, several people restrain the birds and balls strapped to the animals' feet prevent them from using their talons while she conducts a physical exam and obtains blood samples. The exam lasts a mere eight minutes. "Safety is my main concern," said Dr. Fish after examining one of the aviary's Steller's sea eagles. "Those Steller's eagles are ambassadors for their wild counterparts. They are educating thousands and thousands of people about eagles."
