Many people who
live in bear country want to feed birds, and yet the advice from experts
(including the ABA) is that you should not leave feeders out during
the bears' active season, particularly in spring and fall. At the Vince
Shute Wildlife Sanctuary, there is a birdfeeder demonstration area to
show how it is possible to enjoy feeding birds without needlessly impacting
bears. Here is the plan for such a feeder suspension system, which you
can install in your yard.

1 Fixed supports, such as 4x4 posts, trees, the side of a
building, etc.
2
Cable on which to hang feeder(s). Feeder should be minimum of 5 feet
from supports.
3 Winch with locking mechanism
to raise and lower feeder for filling. It must be installed 10 feet
above the ground.
4
Anchor
of some kind (U-bolt or hook) also 10 feet above the ground.
5 Wheel
assembly, which will roll along cable with feeder attached below.
6 Feeder.
7 If desired, extend cable
to another fixed support by using heavier hardware or
by using supports at appropriate intervals.
