Approximate dimensions (empty) are 6" X 24". Slightly longer than a standard tubular feeders. The width dimension when filled (center) is about 4 1/2", and forms a mild hourglass shape. Hanging height of the feeder, may be increased by up to 6", with a simple adjustment for easier positioning.

Feeding ports will not enlarge with use by birds, in a few months or years. The feeder itself will retain its color, and will not permanently stain, and will out last the hanger system. (easily replaceable part)

Still capable of feeding 16 birds when half full, which is when you should top it off. Economical use. Increased efficiency increases economy. All models operate on pennies a day. Average use of a 24-port feeder (150 lb) over a period of a year .24 to .25 cents a day, at a seed cost of .60 cents a lb.

The large surface area that the feeder itself provides is 2 sq. feet, and in addition the edges of the feeder itself form two 24 inch TRUE perches, they are just not the customary round perches. The perching area provided by feeder itself, is like suspending two square feet of ground area, in the air and turning it into a feeder.

The feeder reduces aggression and competitive feeding by providing numerous feeding ports, and the area for their use. Feeding birds becomes more entertaining with the different patterns they can create as they use the feeder.

Quick run down

It will not rust, crack, or rot. There is no condensation built up inside the feeder to degrade the seed, and when it rains the superior ventilation dries the contents quickly. There are no nooks or crannies that are not well ventilated or exposed to sunlight. They open instantly for filling and close just as fast. The area for adding seed is of sufficient size and provides an elliptical opening, allowing for easy filling.

Seed consumption will generally average 150 lbs or less of seed usage over the period of a year for this feeder. It would break every rule in the book, if there was such a book, there is nothing like and there is nothing that works like it. They display a single bird as well as many. From quantity of birds, safety, ease of use, efficiency, accessibility, acceptance, display, maintenance, economical use, versatility, material and construction all been taken into consideration to produce a performance bird feeder. It is so different it was rapidly awarded a US Utility Patent.

These feeders are meant for small flocking birds attracted to thistle seed, which from a nutritional standpoint is superior to all other offerings and actually the least expensive (see below) seed you can provide for birds.

Please remember these feeders have an actual front and back plus two sides. The information provided on this listing is the result of 2 1/2 years of extensive testing "before" offering these feeders for sale.  These feeders build their own audience of birds, so the number of birds you attract will increase, while your effort will decrease.

Squirrels (flying included) DO NOT LIKE AND WILL NOT EAT THISTLE. If the only seed you were to offer was thistle, the squirrels, raccoons, etc. frequenting your feeding area would leave. It is not a native see, flavor is objectionable, and the small size of the heart makes it physically impossible to be used as a food source. No germination of seed beneath the feeder (sterilized to kill weed seeds).

Developed for flocking birds, with group or singles as an added benefit: Goldfinch (all), Pine Siskin, House Finch, Lesser Goldfinch and others. The feeder provides a solid, neutral background to enhance the display of birds. This means the from farther distances the birds will stand out and display better

No assembly on your part. No parts to lose. Fills fast and is easy to hang. Becomes rigid when filled, making the feeder easy to grip and hang. Base feeder construction is a thermoplastic, waterproof, super strong mesh, which provides a wall thickness of about 40 microns. Thickness of 4 index cards. Hanger is a support handle when refilling and the cord is not floppy and useless when re-hanging.

Maintains seed fresh - fully tested for 9 months, with all types of weather conditions. Totally weather resistant. Feeding ports remain open to birds in the worst snowstorm, and the feeder itself remains free of snow. Approximate seed capacity - 4 lbs 6 oz (Over 1 gallon dry measure). Longer intervals between filling. This is not just based on a large seed capacity, but also increased
