Where do I put the nest boxes?
Put the boxes up wherever it is convenient
for you. They can go in trees, on posts
out in the field, on the wall of a building.
Each site has positive and negative points.
In trees, the owls will receive some protection
from the elements, but the young will be
exposed to predators. On a post, the young
will be protected from most predators, but
the box may get hot during a heat wave.
On a building, whatever is below the box
will probably get splattered with fecal
matter.
Where should I not put the nest boxes?
Don't put nest boxes above locations where
vehicles or equipment is parked.
Outside your bedroom window is not a good
idea either, because the young owls can
compete very noisily each time the adults
return to the nest with food.
Owls prefer not to hunt in the area of their
nest box so as not to attract the attention
of potential predators. Multiple nest boxes
in this vicinity will solve this problem
because the hunting areas of the different
nesting pairs will overlap.
Will routine farm operations bother
the owls?
No, regular farm activity will not bother
the owls as long as the box or the post
is not bumped. In most cases they will remain
quietly inside the nest box.
How many nest boxes do I need?
One box will achieve the "warm fuzzy"
thing but will not control your rodents.
Your goal should be to attract as many nesting
pairs of barn owls as your rodent population
can support.
Remember that it is nesting pairs that you
want to attract. Each adult will eat one
rodent a night, but each chick will eat
up to four or five, depending on the size
of the chick and the size of the rodent.
Six boxes across fifty acres is a good start.
Figure you have enough nest boxes when 20
to 30% are not being used at any time during
the year.
If I put up several nest boxes
in the same field, will the owls' territorial
instincts cause conflicts?
Barn owls are not considered to be very
territorial. The number of owls you attract
is a product of the number of rodents in
your field and the number of nest sites
they can find in your area. This means that
you can erect as many nest boxes as you
have space for. And the more nesting pairs
of owls you attract, the more rodents you
will get rid of.
Do I need to do anything special
once I attract the barn owls?
In general, leave the nest boxes alone.
Can I peek in my boxes to check
on the owls?
It is always best to leave the owls in your
nest boxes alone. This is especially true
while the hen is sitting on the eggs, during
January February or March. Scaring her away
at this time may result in her refusal to
return. When the chicks have hatched, you
can safely peek in to see how many you have
without worrying whether the parents will
return.
Should I continue baiting the rodents
after the owls have moved in?
Use Racumin.
What do I do when I find a young
owl on the ground?
The chances are that the youngster's parents
know where it is and they are probably taking
care of it, so unless the owl is injured
or in danger, just leave it alone.
If the owl appears to be hurt or is potentially
threatened, take it to your nearest raptor
rehabilitation center.
How do I capture a grounded barn
owl?
To capture the barn owl, you will need a
sheet, a pair of heavy gloves and a paper
grocery bag.
Start by throwing the sheet over the owl.
Wearing the gloves, grab the owl by both
legs just above the feet while the bird
is still covered with the sheet. Remove
the sheet and turn the owl upside down.
Put it into a paper grocery bag and fold
the top of the bag over to keep the bird
inside.
