We started the week with three Barn Owls suffering from metabolic bone disease, a gunshot Swainson’s Hawk and a Great Gray Owl who had been struck by a vehicle. The week ended on a high note with the banding of 7 American Kestrels and the release of a Swainson’s Hawk.
Three Barn Owls were admitted who had been fed chicken for several days resulting in metabolic bone disease from a lack calcium in their diet. Barn Owls 26-185 and 26-186 had multiple fractures and were euthanized. The damage to Barn Owl 26-187 is more subtle. He is being fed whole mice and supplemented with calcium. I am not very optimistic that we will be successful, but we are trying. Below are x-rays of the three owls.



An x-ray left no doubt that Swainson’s Hawk 26-189 had been shot. The damage to the right tibiotarsus was too extensive to repair and the hawk was euthanized.

Great Gray Owl 26-193 was found in a road near Wallowa. She has a head injury, but seems to be feeling much better after a few days of supportive care. The vision in her right eye needs to be more fully evaluated, but she is eating 9 or 10 mice per day, so has a good appetite!

Seven American Kestrels were banded and moved outside to a hack site. They will soon be released.


The week ended with the release of Swainson’s Hawk 25-443 who had been over-wintered because of her poor feather condition at the time of admission. We suspect her feathers were damaged by shotgun pellets. This spring she molted most of the broken feathers. The new feathers were not completely grown in, but her flight ability was much improved. She will be ready to migrate to Argentina this fall with a full complement of feathers.
