Attracting Bluebirds

Written By DANIEL GERDES

Attracting bluebirds to your yard in the Midwest, especially in Illinois, requires the right combination of food, shelter, and water. Eastern Bluebirds start arriving in Illinois in late February to early March, scouting for nesting sites. Having nest boxes ready by late winter increases your chances of attracting them. Nesting typically begins in April, with two to three broods per season continuing into August. Bluebirds compete with many common non-native birds for territory and this is often a major factor in their nesting success. If you have an open larger yard or property, with reliable food and water and nesting boxes, bluebirds will naturally gravitate towards it. Here are some tips to help attract them to visit, nest and raise their young in your own backyard!

  • Provide the Right Nesting Boxes

  • Use a wooden bluebird house with a 1.5-inch entrance hole to keep out starlings and sparrows.

  • Place the box 4-6 feet off the ground on a pole or post, facing an open area.

  • Add a predator guard (baffle) to protect from snakes, raccoons, and squirrels.

  • Clean out old nests after each brood to encourage new nesting.

  • Offer Proper Food Sources

  • Mealworms (live or dried) are a favorite of bluebirds.

  • Plant native berry-producing shrubs like dogwood, serviceberry, and elderberry for natural food.

  • Avoid insecticides: bluebirds rely on insects like caterpillars, beetles, and spiders.

  • Provide Fresh Water

  • A shallow birdbath (1-2 inches deep) with moving water (such as a dripper or fountain) will attract bluebirds.

  • Keep water clean and fresh, especially in winter with a heated birdbath.

  • Maintain Open Spaces

  • Bluebirds prefer open areas with scattered trees rather than dense forests.

  • Mow selectively to allow foraging in grassy areas.

  • Deter Competitors and Predators

  • Keep an eye out for house sparrows, which can outcompete bluebirds. If they take over a nest box, remove their nesting material.

  • Use sparrow-resistant box designs, such as slot boxes.

  • The battle between native bluebirds and sparrows is very real. Sparrows can be relentless in trying to drive out nesting bluebirds.

With the right setup and setting, you can enjoy bluebirds nesting and feeding in your yard throughout the spring and summer!
