- Abstract
Barred Owls (Strix varia) are generalist predators that take a variety of birds, small mammals, herps, fish, crustaceans, insects, gastropods, and other invertebrates as prey. Here we document 2 different Barred Owl individuals that ingested rough-skinned newts (Taricha granulosa) as prey in northern California. Few vertebrate predators are known to feed on newts of the genus Taricha because they carry a potent defensive neurotoxin (tetrodotoxin) lethal to most vertebrate predators. Our examples suggest that Barred Owls may prey on newts in some areas and that consuming newts is not always lethal to Barred Owls.
