Juneau - Snowy Owl

Snowy Owl (Haliaeetus leucocephalus)

Our new Snowy Owl is a juvenile male who was rescued at anĀ Arcelor Mittal steel mill in Cleveland. He had a badly fractured wing and an infestation of feather lice. After he was stabilized he underwent two separate surgeries to reset his dislocated wing. This injury is one of the most difficult to repair because birds’ bodies start to compensate very quickly. To add to the challenge, northern species like the snowy owl are difficult to sedate and do not recover well from anesthesia. When his joint failed to heal after a second attempt, our veterinarians recommended that no further surgery be attempted on him. While this is not the outcome we had hoped for, we are glad to report that he has shown great promise to become a handsome and dignified educational ambassador.


About Snowy Owls

(Information taken from theĀ Cornell Lab of Ornithology)

At the extreme northern margins of the arctic tundra lives the Snowy Owl, the northernmost, heaviest, and most distinctively marked owl of North America. Largely diurnal, it spends much of its time perched still and silent on prominent lookouts, waiting to make forays for prey.

Population sizes difficult to estimate because of size and remoteness of habitat. No information on long-term population changes, except an apparent decline in northern Europe.

Sound

Generally silent in winter. Call a deep, powerful hoot. Also a series of harsh clicking.
