From World Bird Sanctuary

Some birds are very cooperative for their annual exams. Uxmal, the spectacled owl, has most of her exam done voluntarily. Certain parts of the exam still require restraint for the safety of the bird and staff, such as blood draws, but we can mitigate a lot of stress by having the bird willingly participate in their exams. Husbandry training can be important in getting voluntary weights, feet and body checks, nail trims, and delivery of medications.
