I'm sure screech-owls have visited much more often, but these are the only sightings I have documented. You can see this one has been here the longest I've ever had one. I imagine it has been here ever since I first heard it on Feb 17. I heard it in the courtyard during that night. Mostly it stays at the oasis and can't be heard from the house a block away, and I hadn't visited the oasis at night during the interim. It may be nesting here for the first time ever. One has been observed and photographed in 3 different nest boxes on three different evenings at the oasis, whether the same individual or two different individuals. Here is the first screech-owl photo taken at the oasis. Chris Hortness snapped this on the evening of Mar 9. The two pictures I posted recently are both taken in different nest boxes, so now 3 boxes are depicted with a screech-owl in them.

I have two Mexican Buckeye trees blooming side by side and the coloring is quite different. These photos were taken at the same time in the same light.
