BOSTON — Birds are highly discriminating in their eating habits. But there are four primary food groups that whet their appetites: seeds, berries (including nectar), insects, and meat.
Most seed-eating birds, such as cardinals, jays, and chickadees, flutter and chirp at black-oil sunflower seed. It's high in oil content, which keeps birds warm during winter.
By themselves, sunflower seeds are expensive. Bird feed producers therefore use a variety of price-cutters to make birding an affordable hobby. They sometimes mix sunflower seeds with cheaper millet and oats.
Although sunflower seeds are ideal for several common species, they do not meet the approval of juncos, towhees, song sparrows, and redpolls. Millet seems to please their palates.
Niger thistle seed is a favorite of small-billed seed eaters such as siskins and goldfinches. It's costly, but if you love goldfinches, it's worth it.
Berry (or fruit) eaters such as bluebirds, cedar waxwings, and mocking birds enjoy raisins and slices of oranges, among other fruits. Suet can substitute for many insect-eaters, especially in winter. The fat keeps birds such as woodpeckers, chickadees, and titmice warm in winter.
A creative bird lover offers this gourmet recipe: Heat suet on a stove, until it melts. Add bird seed. Stir. Pour it into molds or cups, chill, and place in feeder.
The following is a list of some common bird species and their food preferences:
