Platform Bird Feeders
Platform bird feeders are simpler than many other feeder
styles, as the basic concept is simply an open platform or
flat area that both holds the bird food and serves as the
perching area for the feeding birds.
Platform bird feeders are popular because
they can be used with almost any bird food, and they
will attract many types of birds that can't use other
feeders like tube feeders, such as many birds that
typically feed off the ground.
Mounting Platform Feeders: These are some of
the most versatile feeders when it comes to mounting options.
Since you may be trying to attract groundfeeders, you can
mount them just above the ground, or somewhat above the
ground on a small post or even a tree stump. An unused bird
bath pedestal is another choice, and it's very common to see
one of these on a patio post. To avoid the loss of seed in
high winds you may want to choose a spot that is a little
sheltered from the wind.
Some birds that are attracted to these feeders include:
Cardinals, especially Northern Cardinals, tufted titmice,
juncos, jays, painted buntings, towhees, chickadees, sparrows
and doves.
One problem that often arises with many feeders are pests
such as squirrels. Some platform feeders try to deal with
this by adding a roof that is low enough that the birds can
still easily feed, but a squirrel will not be able to land on
the feeder and stay put to feed. If squirrels are a real
problem you may need to hang the feeder instead of mounting
it.
It's also good to have some drainage to avoid having the seed
rot from moisture. Many platform feeders have a mesh bottom
that allows drainage but keeps the seed in place. If you
choose this option take care to clean the mesh periodically,
as it's a relatively fine mesh and can be clogged with
debris.
