What Kind of Bluebirds Are in Delaware?
There are three species of bluebirds that live in the United States, but the Eastern Bluebird is the only species found in Delaware. Eastern Bluebirds are found in Delaware and in other states east of the Rocky Mountains. They are frequently seen in open areas, like fields and backyards, where they have plenty of space to hunt for insects. Setting up a bluebird nest box is one of the best ways to attract Eastern Bluebirds to your yard.

Similar Birds to Bluebirds in Delaware
Blue Jays and Indigo Buntings are blue-colored birds that are often incorrectly called “bluebirds.” However, they are different species entirely. Blue Jays are much larger blue-colored birds found throughout much of the eastern and central United States. Indigo Buntings are smaller, but rarer, blue-colored birds that people also confuse with Eastern Bluebirds.

How to Attract Bluebirds in Delaware
The best way to attract bluebirds in Delaware is to put up a nest box in an open area. Since bluebirds are secondary-cavity nesters, they make use of old woodpecker holes, natural tree cavities, and nest boxes to build their nest. They cannot build nests in trees like robins, cardinals, or many other birds.
If you have a medium to large sized backyard in the country, consider putting up a bluebird nest box! If you set up a bluebird house in the middle of February, you could have a nesting pair of bluebirds by early spring.
Learn everything you need to know about attracting bluebirds in the article that I wrote here: How to Attract Bluebirds.
Feeding Bluebirds
If you have already spotted bluebirds in your area, you can also train them to come to a bird feeder. However, they won’t eat the same seeds that you might put out for other birds. At a bird feeder, bluebirds enjoy live mealworms, especially during the summer when insects make up the majority of their diet. During the winter, when insects become scarce, you can attract bluebirds to your feeder with sunflower seed hearts, berries, pieces of fruit, chopped peanuts, and peanut butter.

What Nest Box Should I Use for Bluebirds in Delaware?

The best nest box to use for bluebirds in Delaware is either (1) a wooden nest box with a 1 1/2 inch round entrance hole, or (2) a Gilbertson-style PVC pipe nest box with a 1 1/2 inch round entrance hole. Each of these nest box styles work well for Eastern Bluebirds and they have proven successful at attracting bluebirds in Delaware.
You can compare these two nest box styles on my Recommended Tools page here.
If you already have a bluebird house at home, make sure that it has a round entrance hole that is exactly 1 1/2 inches in diameter. If the hole is too small, bluebirds won’t be able to enter the nest box. But, if the entrance hole is too large, it may allow European Starlings to enter, which are an invasive species that compete heavily with bluebirds for nesting sites. So, make sure your bluebird house is built to the proper size. Learn more about entrance hole size in this article here.

If you want to get involved with bluebird conservation in Delaware, the best thing you can do is to become a bluebird landlord. What is a bluebird landlord? A bluebird landlord is someone who attracts and cares for bluebirds by providing a safe place for them to nest.
