What Species of Bluebirds Live in Pennsylvania?

There are three species of bluebirds that live in the United States, but the Eastern Bluebird is the only species found in Pennsylvania. Eastern Bluebirds find their home in Pennsylvania and other states, primarily 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. 

Even though these birds once saw a population decline in the US, thanks to conservation efforts, Eastern Bluebirds are now common throughout the state.

Here are a few fast facts about Eastern Bluebirds.

Similar Birds to Bluebirds in Pennsylvania

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 Pennsylvania

The best way to attract bluebirds in Pennsylvania 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.

The two best nest boxes that I recommend for Eastern Bluebirds are the following:

  1. A wooden nest box with a 1 1/2 inch round entrance hole (see my favorite one here)
  2. The Gilbertson-style PVC pipe nest box with a 1 1/2 inch round entrance hole (see my pick here)

Each of these styles of nest boxes work very well at attracting Eastern Bluebirds.
