Western Screech Owl


Screech Owl
About Owlivia

On August 5, 2011 Tehama Wild Care admitted a young Western Screech Owl that had suffered an injured left wing due to vehicular collision near a busy road. The vet's exam showed that there were no breaks or dislocations and it was believed to be possibly a soft-tissue injury that would heal with time. But as time went by, the wing showed no improvement in mobility.
She transferred to WERC on August 29 for evaluation as an educational animal. Since she wasn't able to fly at all, staff needed to make sure that she was able to ambulate on her own. This was a critical issue as it was important that the owl be able to right herself if she toppled onto her back and to ensure that she doesn't step onto and impale her bad wing with her talons. Owlivia officially joined WERC's educational animal team in December 2011 and is now a member of the OWL team-Owlivia, Wally the Pygmy Owl, and Luna the Great Horned Owl.

When threatened, the bird stretches its body, tightens its feathers, and extends its "horns" in order to look like a branch stub to avoid detection. Its coloration makes it blend perfectly into the texture and color of the tree bark.
