Gully Cams

A Western screech owl perches near the camera 

but at the edge of the frame where there was no eye shine.

Unless there's a visible bait, sound lure, or water you don't expect owls to come to camera traps. 

Craig set a couple of cameras in or near gullies, which many mammals use as travel lanes.  

He used a punctured can of mackerel under a rock as bait, and a couple of scent lures, none of which should attract owls.

The surprise was that an owl visited each camera.

but bird was close to the center of the frame, thus the eye shine.

You can't rule out the possibility that they were attracted to rodents attracted to the bait.
