Oraristix brea, the Brea owl, is an extinct owl reported from the upper Pleistocene asphalt deposits of Rancho La Brea, Los Angeles, California. It was first described in 1933 by Hildegarde Howard as Strix brea, but this extinct owl was recently placed into its own genus by Campbell and Bocheński (2010). The Brea owl has also been found in the upper Pleistocene asphalt deposits of Carpinteria, California. Oraristrix brea is interpreted as more terrestrial in habits than forest owls because, compared to North American species of Bubo and Strix, it had longer legs relative to its wingspan.
