Deter predators by cleaning up tasty treats, like the fruits or nuts from trees, clearing wood piles and tall grasses, and spraying your yard with unfavorable scents like garlic.
Cardinals are active in the early morning; you may not see them in the afternoon. They may also avoid your feeder in the summer when natural food sources are easier to find.
Fill the feeder early in the day and pay extra attention when food becomes scarce in winter. Cardinals may visit between March and September if you provide safe nesting spaces.
The slightest hint of mold will deter cardinals, so clean your feeder every 2 weeks. Splurge on quality feed, and include favorites like sunflower and safflower seeds.
Cardinals are larger than most birds, so many hanging feeders tilt under their weight and scare them. Try a sturdy, pole-mounted feeder and test their weight in nickels.
Cardinals need water to drink and to bathe, so consider adding a bird bath to your yard. Remember to keep it clean using natural solutions to avoid harming the birds.
