l eft, Gila Woodpeck–
ers commonly peck holes hig h
in the saguaro cactus (top right>.
Often, abandoned woodpecker
holes serve as homes for other
creatures. The tiny 6-inch Elf
Owl takes up housekeeping in
an old woodpecker hole (bottom

the saguaro for a nesting site
- a marvelous tri-partite rela–
tionship of plant and animal
making the best use of a gen–
erally hostile environment.
