Attracting Eastern Bluebirds to Your Backyard

Eastern Bluebirds are beloved for their vibrant plumage and cheerful song, but attracting them to your backyard requires understanding their specific needs. They aren’t seed-eaters, for one. This guide provides practical steps to transform your yard into a bluebird haven, covering everything from housing and feeding to landscaping and predator control.

Understanding Eastern Bluebird Habitat Preferences

Before you start buying nest boxes, consider what bluebirds are looking for. They prefer open habitats with scattered trees or shrubs, providing perches for hunting insects. Think meadows, pastures, and large lawns. If your yard is heavily wooded, attracting bluebirds will be a challenge.

• Open Space: Bluebirds need open areas to hunt insects.
• Perches: Trees, shrubs, fences, and even clotheslines offer perches for spotting prey.
• Nesting Sites: Natural cavities or nest boxes are essential for breeding.

Providing the Right Housing: Nest Boxes That Work

A properly designed and placed nest box is the single most effective way to attract Eastern Bluebirds. But not all nest boxes are created equal.

Choosing the Right Nest Box Design

• Entrance Hole Size: The ideal entrance hole size is 1 1/2 inches in diameter. This prevents larger birds like starlings from entering.
• Box Material: Untreated wood (like cedar or pine) is best. Avoid plastic or metal, which can overheat in the sun.
• Ventilation and Drainage: Ensure the box has ventilation holes near the top and drainage holes in the bottom to prevent moisture buildup.
• Predator Guard: A predator guard beneath the entrance hole deters snakes and raccoons.
• Avoid Perches: This might seem counterintuitive, but perches actually help predators access the nest.

Nest Box Placement: Where to Put Your Bluebird House

Placement is almost as important as the design itself.

• Open Area: Mount the box in an open area, away from dense foliage. Bluebirds need clear flight paths to and from the nest.
• Height: Mount the box 5-10 feet above the ground.
• Facing Direction: Face the entrance hole away from prevailing winds (typically north or east).
• Spacing: If you’re installing multiple boxes, space them at least 100 yards apart to minimize competition.

Monitoring and Maintenance: Keeping Your Nest Box Habitable

Regular monitoring and maintenance are crucial for success.

• Monitor Weekly: Check the box weekly during the nesting season (spring and summer) to monitor progress and identify any problems.
• Remove Old Nests: After each nesting cycle, remove the old nest to prevent parasites and encourage future use.
• Repair Damage: Repair any damage to the box promptly.
• Consider a Noel Guard: These guards deter house sparrows, a non-native species that aggressively competes with bluebirds for nesting sites.

Offering the Right Food: What Bluebirds Eat

While Eastern Bluebirds primarily eat insects, especially during the breeding season, providing supplemental food can attract them and help them thrive. They are NOT seed-eaters, so offering sunflower or mixed seed will be ineffective.

Live Mealworms: A Bluebird Magnet

Live mealworms are a bluebird delicacy and the most reliable way to attract them to your yard.

• Where to Buy: Purchase mealworms from a reputable supplier online or at a local pet store.
• Feeding Method: Offer mealworms in a shallow dish or platform feeder.
• Timing: Offer mealworms consistently, especially during nesting season and cold weather.

Fruit: Another Bluebird Favorite

Bluebirds also enjoy fruit, particularly berries.

• Native Berry Bushes: Plant native berry bushes like dogwood, serviceberry, and elderberry.
• Cut Fruit: Offer cut-up grapes, blueberries, or cranberries in a dish.

Suet: For Winter Sustenance

Suet, especially varieties with insects and berries, can attract bluebirds during the winter months when insects are scarce. You can find our suet feeder recommendations in our article on the Best Suet Feeders and Which Birds They Actually Attract.

Water: A Consistent Source is Key

Like all birds, Eastern Bluebirds need a reliable source of fresh water. A birdbath is an easy way to provide this. Clean it regularly to prevent algae growth. See our article, Do Birdbaths Actually Attract More Birds? (And Which Type Works Best), for guidance on choosing the right setup.

Landscaping for Bluebirds: Creating a Bluebird-Friendly Habitat

Transforming your yard into a bluebird haven involves more than just providing nest boxes and food. Consider these landscaping tips:

Plant Native Trees and Shrubs

Native plants provide food and shelter for bluebirds and other wildlife.

• Berry-Producing Plants: Choose native berry bushes like dogwood, serviceberry, and elderberry.
• Insect-Attracting Plants: Plant native wildflowers and grasses that attract insects, a primary food source for bluebirds.

Reduce or Eliminate Pesticide Use

Pesticides can harm bluebirds directly or reduce their food supply. Opt for natural pest control methods whenever possible.

Provide Perches

Bluebirds need perches to hunt insects. Leave some dead branches on trees or install perches near open areas.

Maintain Open Areas

Keep lawns mowed and clear away dense vegetation to create open areas for bluebirds to hunt.

Controlling Predators and Competitors

Protecting bluebirds from predators and competitors is a critical part of attracting them to your backyard.

Predator Control

• Nest Box Placement: Place nest boxes away from dense foliage and structures that predators can use to access them.
• Predator Guards: Install predator guards on nest boxes to deter snakes, raccoons, and other predators.
• Monitor for Predators: Be vigilant and take action if you spot predators near your nest boxes.

Competitor Control

• House Sparrows: House Sparrows are aggressive competitors that can evict bluebirds from their nests. Monitor your nest boxes and consider using sparrow traps or Noel guards to control their populations.
• European Starlings: Starlings can also compete with bluebirds for nesting sites. Ensure your nest box entrance holes are no larger than 1 1/2 inches to prevent starlings from entering.

By implementing these strategies, you can dramatically increase your chances of Attracting eastern bluebirds to your backyard and enjoy their beauty and song for years to come. Remember that patience is key, and it may take time for bluebirds to discover your yard and establish themselves. But with the right combination of housing, food, water, and landscaping, you can create a bluebird paradise.
