Eastern Bluebirds are a vivid spectacle in open woodlands, fields, and meadows across Eastern North America. Males flaunt bright blue heads and wings, with rust-colored throats and white bellies. They measure about 7 inches, sitting between a sparrow and a robin in size. Nesting in tree cavities or man-made boxes, they prefer areas with scattered trees and shrubs.
Insects like beetles and grasshoppers form over half of their diet, although they turn to fruits and berries in colder months. Their pale blue eggs hatch into fledglings that leave the nest in three weeks. Want to attract these beauties to your yard? Keep reading.

Eastern Bluebirds build cup-like nests in old woodpecker holes, a preferred natural choice for them. Proper nest box placement mimics this habitat, attracting bluebirds. For successful bluebird nesting, choose areas with scattered trees, shrubs, and make sure predator guards on boxes are present.
Diet
Eastern Bluebirds primarily feed on insects such as beetles, crickets, grasshoppers, and caterpillars, making up more than 50% of their diet. In colder months, they switch to consuming fruits and berries, ensuring they stay nourished year-round.
Over 50% Beetles, Crickets, Grasshoppers, Caterpillars
Eastern Bluebirds thrive on a protein-packed diet, primarily consisting of beetles, crickets, grasshoppers, and caterpillars. Their foraging behavior involves:
- Spotting insects from perches, thanks to their keen vision.
- Dropping swiftly to the ground to capture prey.
- Returning quickly to their perch to eat.
This diet’s seasonal composition guarantees these birds the nutrients needed for survival and energy.
Fruits and Berries During Colder Months
As temperatures drop, Eastern Bluebirds adapt their foraging strategy with a seasonal diet shift. You’ll notice them favoring berries, which offer excellent nutritional value essential for winter survival. Look for them munching on dogwood, sumac, and holly berries. This berry preference helps sustain them when insects are scarce, keeping these vibrant birds healthy and active through the challenging colder months.
Behavior

Attracting Bluebirds to Your Yard
To attract Eastern Bluebirds to your yard, provide nest boxes, and plant native trees and shrubs for natural habitat. Additionally, offering mealworms at feeders and avoiding pesticides will create a welcoming environment for these vibrant birds.
Provide Nest Boxes
Provide a nest box before breeding season. Verify the design is proper, with a small entrance hole. Place it in a safe spot, attach predator guards, and monitor populations to support winter nesting.
Plant Native Trees and Shrubs
Planting native trees and shrubs supports bluebirds in various ways:
- Enhance insect populations they hunt.
- Provide natural nesting spots.
- Offer shelter from predators.
- Foster long-term conservation efforts.
Engage local nurseries.
Offer Mealworms at Feeders
To attract bluebirds, place mealworms in feeders. They’re a high-protein treat that bluebirds love, especially during breeding season. Position feeders near nest boxes to maximize visits and guarantee delighted bluebirds.
Avoid Pesticides
Avoiding pesticides is essential for bluebird health. Pesticides can reduce insect populations, harming their food source. Additionally, exposure can affect bluebird health and reproductive success, indirectly aiding bluebird predators and bluebird parasites.
Conservation
Preserving the Eastern Bluebird necessitates comprehension of their conservation status and addressing principal challenges. Their population dynamics have experienced both highs and lows, chiefly due to habitat loss and competition for nesting sites.
To assist in reversing any decline, you can engage in nest box programs which provide secure sites for these birds to breed. Installing boxes in your yard offers an immediate refuge.
Citizen science projects, such as bird counts and monitoring efforts, play a major role in tracking bluebird populations and informing conservation strategies. By getting involved, you help the Eastern Bluebird and contribute to broader ecological knowledge and preservation efforts.
