Well Dang!
I'd been eagerly watching my owl box since an owl visited it for one day in mid October. Only squirrels had occupied it since. At dusk yesterday I got excited when I saw a face with white on it which would rule out a squirrel. Grabbed my camera, turned on the flash since it was so dark. Dang it, that is not an owl either. Has to be a pretty small possum to get in that opening.
Photo 2:
Taking The Slow Elevator Down
When the interloper saw me, it sank out of sight in slow motion, was hilarious to watch. I made all kinds of interesting and coaxing sounds but it refused to look out again. This morning no sign of it. Back to hoping that someday a screech owl couple will move in & raise babies.

Was pointing out a WAVI to some visiting birders and this little punk flew in. Watched it for some time. Seem to center around an Aesculus that spilt over the trail
https://www.inaturalist.org/observations/81123855
that grew over the path. It was next to a Red Elderberry (Sambucus racemosa) and that next to a California Wax Myrtle (Morella californica) ... a troika of bird magnets.
.
Most easily detected by its constant tswee call ... would also fly across the trail to the SW side but not very far. In the mix with WAVI and HUVI
