Do you have Bears in your neighborhood?
Have you ever experienced bear damage at your bird feeders? We live in a rural enough area to have possible bear damage from time to time. Sometimes they just bend down the pole that the feeder is on and eat their fill or maybe take the entire feeder, (I've lost a couple feeders over the years due to bears). Other times they chew on the feeder itself until the seed comes out, (see photo below). I usually recommend bringing your feeders in at night (when most of the damage is done), but sometime this is just inconvenient!
We now have a bear proof feeder available. It is a very heavy steel feeder that holds 3 1/2 quarts of seed. It will need to be hung on a sturdy branch or pole system, but the bears will not be able to chew this feeder! (see photo below).
I would also recommend using our Hot Pepper Seed Cylinders to deter mammals from eating your bird seed. Only mammals have a sensitivity to pepper being "hot", birds eat this ready with no ill effects. They may taste pepper, but they don't taste "hot"
