Beat the squirrels! By lois54
I ordered this birdfeeder a couple of weeks ago, as a replacement for one I had for several years. I had purchased the first one at a local hardware store but could not get it this year - don't know why. It is a terrific feeder and is the ONLY one I have found for which the squirrels cannot get the seed!!!

Thank you for sharing this experience. Birds can be very picky eaters and may take some time to become accustomed to a new feeder in their environment. To encourage the birds to try the feeder, we recommend removing established feeders in the area. Also, placing a shiny pie pan filled with seed under the feeder will help attract birds to the area.

Please feel free to contact our Consumer Relations Team at 1-855-PERKYPET (1-855-737-5973) with any additional questions.

Looks good in catalogue photo. By Wally
After filling feeder with seed I hung it up. The plastic bin slipped from the cover, fell to the floor and broke, irreparably. I can't legitimately rate with a single star.

Works perfectly and the birds love it! By MuskokaLaura
We've been enjoying this feeder for a few weeks now and the small birds are really enjoying it and the blue jays and squirrels both seem to be unable to get at the seed which is great!!!

Rain feature. By Nora
I was impressed with this feeder as it keeps the rain out of the bird food so it's not moldy. The service was great! The first one I ordered was damaged in transit and the second one was replaced immediately with no hassles.

Fortress birdfeeder the best By chazz
With this purchase I now have three of the Fortress feeders. They are the only ones I use any more. They protect the birds and the seed from the rain or snow, and if placed correctly, stop squirrels from stealing the seed. They are also easy to fill. Keep making them. Don't replace them with a "prettier" version.

Third set of these By Gammy Jane
We just received our 3rd set of this particular feeder. The only reason that we had to replace the older ones is either the plastic eventually dried and got brittle or the squirrels figured out how to take the top off. This is the only feeder that we have had that really discouraged those fuzzy creatures. Really do recommend it.

works as advertised By
Had this feeder up for over a week and squirrels don't touch it. So it met that purpose. It seems durable and has large capacity so I will not need to refill but every other week now.The dome keeps seed dry and discourages squirrels. Unfortunately it is still hard for my resident titmouse and cardinals. The chickadees are learning but the friendly titmouse are not as adapt to change. Cardinals, doves, woodpeckers are too big for this feeder. So I have a more open feeder for them. Unfortunately, despite red pepper and seed coatings, it is still overrun by grey squirrels. So this is a good feeder but only one tool in the arsenal. Also, the length of the hanger is not adjustable because of lid. So make sure your hanging spot has at least 15 inches of clearance.

Hanging Your Feeder

Bird Baths - A clean and reliable water source is an excellent way to attract birds to your yard, especially those birds that do not necessarily eat seed or nectar. All birds will seek out a water supply, not only for drinking but also for keep themselves clean and healthy.

Bird Houses - These are a good way to attract those species of birds that nest in holes. These structures should be made of an untreated wood (pine, cedar, etc.) and should have ventilation and drainage holes. It should be durable, and easy to check and clean.

Feeder Care

Keeping your feeder clean and full of fresh bird seed is very important to the health of visiting birds. It is recommended that you clean your wild bird feeder every two weeks.
