Key ways to keep birds of various species coming to feeders:

• Multiple foods and multiple feeders, arranged at different heights.

• Eight to 12 feeding stations clustered in groups of three or four.

• Year-around water — especially if it drips, gurgles, splashes or mists.

• Place feeders and baths so they don't aid cats and raptors from killing birds.

• Clean feeders monthly to eliminate mold, bacteria and viruses.

• Plant shrubs and crabapple trees that produce bird-friendly fruit.

• Select seed and suet high in protein and fat to boost cold-weather birds.

• Use live mealworms to attract spring bluebirds.

• Safflower seed attracts cardinals and other birds and isn't favored by squirrels.
