counter-balancing feature harmlessly ejects squirrels and helps to prevent
loitering. The two-sided seed
hopper stays upright while the exterior shell pivots around, keeping the
seed intact and the squirrels at bay. Also, heavier birds will tilt the
RollerFeeder just enough to prohibit them from feeding from the tray, this
unique design is adjustable with weights provided.
I'm so impressed with the ingenious design, solid construction and
squirrel-confounding entertainment that I
just wanted to share - but I receive no benefit, financial or otherwise from this
A RollerFeeder is a
bird feeder that
fully spins in a clockwise or counter-clockwise direction.The feeder allows small birds to feed while preventing squirrels
and large birds from feeding.The
feeder typically hangs directly off a tree limb, tree trunk (or any horizontal
and is best for birds such as chickadees, finches, nuthatches, titmice, and other
small birds.When animals
such as squirrels, raccoon’s, or large birds climb or land
on the feeder, the outer shell, perch, and shaft sleeves spin. The fully
rotational design prevents the unwanted visitor from resting or climbing
about the feeder, and at the same time, closes off access to the feed
shell quickly rocks back into feeding position and is ready for the next
chickadee to come along.
A seed container is bolted to a shaft.
The outer shell spins around the seed container in a clockwise or
shell includes a perch platform, a counter-balance, and a
window opening that permits access to the feed ports by small birds. When
a rodent animal or large bird climbs or lands on the feeder, the rotating
shell dislodges the unwanted
visitor and closes access to the seed tray.
The RollerFeeder has been
tested and in the field (customer owned)
since 1998. The test sites are located in the northern woods,
and city environments. In most cases, the feeder hangs directly from a
tree limb or hanger without other squirrel deterrent
etc.). RollerFeeder has consistently prevented feeder
problems such as rodent animals and
birds i.e. Grey squirrels, Red squirrels, Raccoons,
Starlings, Blackbirds, etc. RollerFeeder
also has its own on-going test site with three feeders, they hang in the middle of a large pine tree with several branches
nearby to make it easy for squirrels to launch from.
