The main difference between hanging bird feeders and platform bird feeders is that with a hanging bird feeder the bird seed is dispensed through a crack or a small opening in the bird feeder. With a platform bird feeder the bird seed is placed on a platform, or a plate and the birds peck the food from a pile or scattering.
With a platform bird feeder, or a tray bird feeder the birds that are attracted depends on the seeds, but if you are using a platform bird feeder, or fly thru feeder then you may end up seeing a cardinal and other various birds.
Platform bird feeders can also be squirrel proof. By having your platform bird feeder hang, squirrels are less likely to reach your bird seed, saving you money and allowing the various birds to eat. Some platform bird feeders, or tray bird feeders come with a screen big enough for the birds beaks, but too small for the hands of the squirrels, this is a great feature.
Platform bird feeders and tray bird feeders also know as ground bird feeders are easy to maintain and clean, and will bring different types of birds to your backyard than that of a hanging bird feeder. If you decide to buy a platform bird feeder, be sure that you have an adequate location in your yard before you make the purchase
