Bird-X, Inc. is the
world’s leading bird
control specialist and
supplier of unique,
effective and
ecologically safe bird
repelling products.
We have utilized the
latest in patented
technology and
materials to develop
Sparrow-Free
Magic Halo.
The product is a
hoop device
consisting of a series
of wires attached to
the top of a
birdhouse or feeder,
extending beyond its
extremities, under
which all birds
intending to use the
feeder must pass.
Studies have shown
that certain bird
species, including
house sparrows, will
not fly under
elongated wires.
Magic Halo was
developed after
decades of research
into risk aversion
and foraging habits
of birds by Dr. R.J.
Johnson at the
University of
Nebraska, Lincoln.
Dr. Johnson is a
professor of Wildlife
Biology and
Extension Wildlife
Specialist in the
School of Natural
Resources at UNL.
