What Happened to the Squirrel Bouncer?
The Bouncer by Varicraft is one of the newer additions to squirrel-proof-bird-feeders. The four perches are weight-calibrated. They will support the light weight of birds, but as soon as too much weight is put on them, i.e. squirrels, the mechanism causes the perch to collapse, swinging under the feeder instead of out to the side of it.
As with the Roller Feeder, no batteries are used, which is an advantage.
One disadvantage over the roller feeder, however, is that the perch weight allowance is not adjustable. The perches come with a setting sensitive enough to keep off the heavier birds such as grackles and starlings, but they can’t be fine-tuned to meet your specific need.
This feeder should work fine for squirrels that reach it from any direction, whether they climb down to it from above or jump from below; the feeder is long enough so that a squirrel cannot hang from the top and still reach the perches. He must put some weight on the perches, which will cause tbem to collapse.
This squirrel-proof bird feeder used to be carried by Duncraft, but for some reason, it has disappeared off their website.
