Design:

Some birds prefer hanging feeders - finches, for example. Others, like Evening Grosbeaks, would rather eat from a simple platform feeder. Many species will feed at both types, including chickadees and nuthatches. Still others, such as sparrows and juncos, prefer their seed sprinkled on the ground. For variety, you may want to use both types and spread plenty of seed under your feeders as well.

Durability:

Your feeder should be able to withstand harsh conditions, particularly if you live in a region where snow, ice, and frigid temperatures are factors. Make sure your feeder is of sturdy construction. Many designs use heavy-duty metal fittings, which will help prevent squirrels from damaging the feeder and getting at seeds meant for the birds.

Consider hanging a suet basket:

This will attract woodpeckers and other species. Remember, suet goes rancid quickly in temperatures above 70 degrees F, so if you live in a warmer climate, you should buy suet cakes made from rendered beef. These last longer. If you love hummingbirds and live in a southerly region, a hummingbird feeder is a nice way to enhance your feeding station.

Related equipment:

Not all creatures that visit your feeders will have wings! Squirrel baffles (usually domes that fit over the feeder itself) will help discourage squirrels from helping themselves to the seed in your feeders. Also, if you don't have a good place to hang your feeder, a pole mount will help keep squirrels, cats, raccoons, and other uninvited guests off your feeders.
