Sometimes the entrance to a bird nest in a saguaro appears heart shaped.
Here's a random heart on a decaying saguaro boot. A saguaro boot is the woody plant tissue of the saguaro nest cavity which remains long after the cactus dies.
It's hard to see, but after I uploaded the picture, I saw a tiny heart above the heart shaped cutout on the edge of the boot.
It's fun to discover random hearts! See more hearts at Clytie's Random Hearts.
