While platform feeders will attract perching (finch chickadees, titmice, etc.) and clinging birds (woodpeckers, nuthatches, etc.), their primary purpose is to attract ground feeding birds such as cardinals, grosbeaks, doves and others.  “Ground” feeding birds don't mean that they only feed on the ground.  Rather, their feet are such that they want a flat surface. The platform feeder meets that need. The larger the platform, the more birds you’ll get. Since ground feeding birds feed on a variety of seeds in the field, we recommend that you place a good blend in these feeders.
If you want a bit of color on your feeder without taking a chance of toxin harming the birds, consider this one by Woodlink. It has the high qualities of the above feeders and will attract chickadees, titmice, finch, Goldfinch, cardinals and many others.
Another Birds Choice hopper feeder has the identical qualities and dimensions as the WC2-100S except that it has suet cages on each side to attract the woodpeckers, nuthatches and chickadees. You will truly enjoy the number of songbirds and woodpeckers that come to this feeder.
This is a complete feeder: suet for woodpeckers and nuthatches, seed for the songbirds and ground feeding birds, and fruit for fruit eaters such as the waxwing, oriole and others
This larger feeder has the same great features as the other Birds Choice feeders described above; solid cedar, plated heavy duty hardware, removable screen base for easy cleaning, and more.
