A Guide to North American Bluebird Species

Bluebirds are like little pockets of the sky that grace North America with their vibrant colors and melodic songs. These charming avian wonders can turn your backyard into a haven for nature lovers and birdwatchers. We’ll take you on a journey through the enchanting world of North American bluebird species. From the Eastern Bluebird to the Mountain Bluebird, let’s explore these azure gems that bring joy to our landscapes.

The Eastern Bluebird

Sialia sialis

Eastern Bluebirds, often considered symbols of hope, are native to the eastern United States. Their striking azure plumage, with a rusty-orange breast, instantly captures the heart. These lovely creatures are often seen perched on fence posts, scanning for insects to devour.

Habitat and Range

Eastern Bluebirds are primarily found in open woodlands and meadows across their extensive range, which stretches from southern Canada down to Mexico. They nest in cavities, making birdhouses a popular addition to gardens.

Eastern Bluebirds are incredibly adaptable and can be found in various habitats across their expansive range. Some of the key environments they inhabit include:

Open Woodlands

Eastern Bluebirds are frequently spotted in open woodlands, particularly those with scattered trees and moderate understory vegetation. These habitats provide a perfect balance of shelter and access to their primary food source: insects. An example of such a habitat is the mixed pine and hardwood forests of the Eastern United States, such as those in the Great Smoky Mountains.

Meadows and Grasslands

These charming birds also thrive in open meadows and grasslands. These environments offer an abundance of insects, including grasshoppers, crickets, and caterpillars, which make up a significant portion of their diet. One example of such a habitat is the extensive grasslands in the American Midwest, where Eastern Bluebirds can be commonly sighted.

Suburban and Agricultural Areas

One remarkable aspect of Eastern Bluebirds is their adaptability to human-altered landscapes. They are often seen in suburban neighborhoods, parks, and farmlands, where they have embraced nesting boxes provided by enthusiasts. For instance, the rural suburbs of the American South are frequently home to Eastern Bluebird populations.

Forest Edges

Eastern Bluebirds are known to favor the edges of wooded areas, where forests meet open spaces. These transitional zones offer the birds a combination of shelter and opportunities for insect hunting. An example of such a habitat can be found in regions like the Great Smoky Mountains, where forested areas meet open fields and meadows.

Eastern Bluebirds are known for their distinctive nesting habits and their preference for cavity nesting. They often use natural tree cavities or, increasingly, artificial nest boxes provided by enthusiasts and conservation organizations. These birds are a testament to nature’s adaptability and are cherished for their role in controlling insect populations and adding a touch of azure beauty to our landscapes. Creating suitable environments and offering nesting boxes, you can contribute to the conservation of Eastern Bluebirds and enjoy the privilege of observing these vibrant, melodious birds in your own backyard.

Nesting and Mating

Bluebirds are known for their monogamous relationships. They choose their mates carefully and often return to the same nesting sites. Providing them with suitable nesting boxes can help these beautiful birds thrive.


Eastern Bluebirds are insectivorous, feasting on a diet primarily composed of insects, such as grasshoppers, crickets, and caterpillars. This diet makes them a valuable ally in controlling garden pests.

The Western Bluebird 

A Symbol of Joy in the West

Western Bluebirds (Sialia mexicana), a symbol of joy in the western parts of North America, paint the landscape with their vivid blue. These birds are often found in open woodlands, and their presence is a treat for bird enthusiasts.

Habitat and Range

The Western Bluebird thrives in sagebrush deserts, grasslands, and open woodland habitats across western North America. Nesting boxes are essential for their survival, as they often face competition for natural nesting cavities.

Nesting and Mating

Just like their Eastern cousins, Western Bluebirds are monogamous. They form strong bonds with their mates, and their charming courtship rituals are a sight to behold.


Western Bluebirds predominantly feed on insects like beetles, spiders, and moths. Offering a variety of insects in your garden, you can attract these azure wonders.

The Mountain Bluebird 

The Sky’s Serene Painter

The Mountain Bluebird (Sialia currucoides), with its serene azure plumage, is often described as the “sky’s painter.” These birds bring a touch of heaven to North America’s high-altitude landscapes.

Habitat and Range

Mountain Bluebirds prefer open country habitats and are commonly found in mountainous regions. Providing artificial nesting boxes can greatly aid their breeding efforts.

Nesting and Mating

Mountain Bluebirds exhibit the same monogamous tendencies as their Eastern and Western relatives. Their nests are delicate creations of grass, feathers, and twigs.


This species, like other bluebirds, has an insectivorous diet. Serving a platter of insects, you can attract Mountain Bluebirds to your surroundings.
