In building your own upside down suet feeder, you only need two basic materials. All you need to have are plywood and a wire mesh. Figure 1 indicates how a finished upside down suet feeder looks like. But before anything else, here is a background about typical suet bird feeders. Suet feeders are special because of two main reasons wherein it can only hold a certain type of bird seed and second, it can only accommodate a limited variety of birds. You might want to try out having another special feeder design which is specifically intended for hummingbirds or orioles because this type of seeder only holds nectars. Suet is a certain type of bird food created from beef or mutton. You can purchase blocks of suet, store it in the freezer and take a piece to place in your feeders every now and then. Suet bird feeders provide an alternate source of important nutrients for birds such as cardinals and woodpeckers when normal food supply is low. It is during the cold season wherein suet feeders can be best utilized. Since suet is made up of animal fat, it melts easily once exposed to warm temperature which will not be any more appealing for the birds.
Almost all types of birds love suet. You might think that it would be better to have any type of feeder for every kind of bird but as you go along, you will notice that the bigger birds cover the whole area. Chickadees and jays will not eat anymore because of this.

Building an upside down suet feeder may be the best option. Particularly, those birds with the ability to hang themselves upside down will benefit from this design. Thus, you can discourage starlings and even squirrels from eating up the suet.

Use wood glue to stick together parts and then nail or screw them together. Bore some holes on the roof assembly and pass through nylon strings which you will use to hang your feeder eventually.

Next, you need to have a small passageway for you to put the feeder inside and this can be done by using a small hinge which will serve as a mini-door on the roof or on the walls. The purpose of wire mesh here is that it is installed as the base so birds can easily peck the suet. You may paint your feeder to make it aesthetically attractive. It is that simple! Buying a new one is not needed for you to help the environment. This very humbling act will definitely feed the stomachs of those birds. Make sure that your upside down suet feeder is properly hanged so that birds can easily access it. To gather birds in a much quicker way to your feeder, make a food trail by spreading it towards the tree branches. Make sure that you have a good vantage point so that you can enjoy the moments where birds clearly flock toward your suet feeder.
