In the Garden

Not Burrowing, Little Owl.

Very similar visually, but different in some significant ways.

Little is on the left above, Burrowing on right.

Little has mainly vertical belly markings, Burrowing more horizontal.

Little lives in Eurasia, Burrowing in the Americas.

Little lives in places maintained by humans, like parks, orchards, fields near trees, Burrowing lives in plains, grasslands, and deserts where it is more open.

I'm unsure if that is meant to be its house. It seems it could be, but seems a bit poor designed for weather. No idea what it would be otherwise though...
