FAQs on Blue Bird Species Found in Connecticut

What should I consider when setting up a nest box for Eastern Bluebirds?

When setting up a nest box for Eastern Bluebirds, consider the following tips for the nest site: Choose a location that is open with scattered trees and avoid heavily wooded areas. The entrance hole should be about 1.5 inches in diameter to prevent larger birds from entering. Install a predator guard on the pole to prevent predators like snakes and raccoons from accessing the bluebird nest box trails below. Make sure the nest box has ventilation holes at the top and drainage holes at the bottom. Also, regularly monitor the nest box for signs of house sparrows, European starlings, or other pests, and remove their nests if found.

What type of food should I provide in a bird feeder to attract Eastern Bluebirds?

Eastern Bluebirds primarily feed on insects, but they also enjoy fruits and berries. In a bird feeder, you can provide mealworms, which are a favorite of bluebirds. Sunflower seeds are also appreciated but offer them in moderation as bluebirds primarily eat insects. During winter, suet cakes with embedded insects can be a good option to provide the necessary fats and energy, especially for male Eastern bluebird. Additionally, planting native trees and shrubs that produce berries can also help in providing natural winter food sources.

How to attract bluebirds to your backyard?

Attracting bluebirds can be a rewarding experience as they are beautiful birds and beneficial to the ecosystem. To attract bluebirds, set up nest boxes in your backyard as they prefer nesting in boxes or natural cavities. Make sure the entrance hole is the right size for small birds to deter larger birds and predators. Also, place the bluebird nest box plans or boxes in open areas with scattered trees and away from heavily wooded areas. Providing bird feeders with sunflower seeds can also help attract them. Regularly clean the nest boxes and remove old nest materials to maintain a neat nest environment

How to control house sparrows from occupying bluebird nest boxes?

House sparrows are an invasive species and can pose a threat to nesting bluebirds by taking over their nest boxes. To control house sparrows, make the entrance hole of the bluebird nest box smaller as house sparrows prefer larger entrance holes. Also, placing the nest or bluebird nesting box in an open area away from buildings can discourage house sparrows as they prefer nesting near buildings. Regular monitoring of the nest boxes and removing any house wrens or sparrow nests found can also help in controlling their population.
