Last week was a no-show. Three cams, no pictures.
The hollow canyon live oak was my biggest disappointment.
I was about to leap squirrel-like into its mossy arms when I noticed my camera lying there face down at my feet.
Apparently something dislodged it to reach a dab of castoreum, and it tumbled down through the hollow trunk.
What to do?
Defer further attempts at a cavity set.
I set the camera away from the tree to see what manner of beast caused the disturbance.
Plan B will depend on the critter.
