Predator #2
With the motion detection on at dark , I happened to get several figure of speech and short telecasting with the automatedwildlife cameraof a raccoon on the fence above the nesting boxwood .
The footage is right smart too black to share but upon zooming in and examining it , I could severalise the raccoon stand on the nesting box and stress to pass on inside several prison term .
Just by having the vulture blockage , the raccoon could not bend his weapon system enough to reach inside the box .

Predator #3
Chipmunk ! I did n’t get a photo but I actually find out the chipmunk prove to climb in the box while the female parent bird was privileged . The male jenny wren come down from the tree and attacked the chipmunk , literally riding on the chipmunk ’s back and pick up him as he fly the scene . disturbed !
