northern saw-whet owl also adopts
nest boxes, although it favors a
2-inch entrance hole.
Some larger owls also nest in
cavities, including barn and barred
owls. If you live in farm country,
you may be able to place a barn owl
box at the edge of open fields or in a
barn loft. Barred owls favor dense,
swampy woods, and they like boxes
that are high in trees.
3 Say no to insecticides. To
successfully lure owls to your
space, you have to also attract the
creatures they hunt. Screech-owls
feed on large insects, such as moths
and beetles, and small animals
such as mice. If you use insecticides
or rodenticides around your
garden, those poisons may wipe out
the prey before the owls find them.
Worse, the poisons may be passed
along directly to the owls.
4 Keep cats indoors. Even if
they’re well-fed, prowling house
cats kill many small wild animals.
Wiping out populations of mice,
voles, lizards and other creatures
may not leave enough to support
a family of screech-owls or other
small owls. On the flip side, a cat
that wanders outside at night
might become a meal for a large
species like a great horned owl.
It’s better for everyone to keep
house cats inside houses where
they belong!
Barn owls may
raise their young
inside man-made
structures, like
nest boxes, barns
and even homes.

have seen and heard several kinds
of owls in their Ohio yard. They’ve
even seen a snowy owl over a
distant field, but they don’t claim
credit for attracting it!
Signs of
Owls in Your
Neighborhood
They’re masters of disguise,
but look for these clues.
SOUNDS
Owls in towns and cities are
often less vocal than those in
wild country. But late at night,
after traffic quiets down, listen
for them calling.
PELLETS
Owls often swallow their food
whole, later coughing up the
indigestible parts. You may find
“owl pellets” of matted fur, tiny
bones, and insect scales under
dense evergreens where the
owls have roosted.
WHITEWASH
When owls find a roosting
spot, they may use it for several
days. Their droppings accumulate
as “whitewash” on the ground
or on the tree trunk below
their perch. JOHANN SCHUMACHER DESIGN
