Well, not quite. Kevin McGowan, a bird behavior expert at the Cornell Laboratory of Ornithology, tells The Dodo that the bird appears relaxed, but what comes off as a smile or laugh is actually panting. "It's a calm, hot owl in a brightly-lit bird hospital," he says.
Given that there are multiple owls in the clip, the video was presumably taken at a bird hospital or sanctuary. It's unlikely it was shot in a home - owls, despite their Harry Potter charms, are illegal to own privately in the U.S.; the carnivorous and taloned birds, moreover, do not make good pets. The Dodo has reached out to Poley for comment.
