The Eastern Bluebird: Pennsylvania’s Iconic Species

The Eastern Bluebird is a small thrush with a chubby body and a big, round head. Its bright blue back, rusty-red breast, and white belly make it one of the most recognizable bird species in Pennsylvania.

These birds prefer open grassy areas with scattered trees or perches, such as fields, meadows, and parks. They are also common in suburban areas with well-manicured lawns and gardens. Eastern Bluebirds are typically non-migratory and can be found in Pennsylvania year-round, although they may move to lower elevations during the winter months.

Eastern Bluebirds are cavity nesters, which means they require a pre-existing hole or cavity to build their nests. They will use old woodpecker holes, natural crevices, and nest boxes. In Pennsylvania, conservation efforts have been made to install and maintain nest boxes for Eastern Bluebirds, which has helped increase their populations.

When it comes to behavior, Eastern Bluebirds are known for their melodious song and their habit of perching on low branches or fence posts to watch for insects. They mainly eat insects and fruit in the summer, and switch to a diet of berries in the winter.

Overall, the Eastern Bluebird is an iconic species of Pennsylvania and a favorite among bird enthusiasts. Its striking colors, pleasant song, and adaptability to human environments make it a joy to observe and protect.

Habitat: Mountain Bluebirds prefer open grasslands and meadows with scattered trees for nesting. In their breeding range, they live in higher elevations, often in areas with harsh weather conditions like snow and wind.

Tips for Attracting Bluebirds to Your Yard in Pennsylvania

If you want to attract bluebirds to your yard, there are several things you can do to create a welcoming habitat for them.

3. Provide Water

Bluebirds need a source of clean water for drinking and bathing. You can provide this by setting up a shallow birdbath or fountain.
