When it comes to birds, few are as beloved as the blue jay and the bluebird. Both species are known for their striking blue coloration, but they have many differences that set them apart from one another. In this comparison guide, we’ll explore the unique characteristics, behaviors, and habitats of blue jays and bluebirds to help you appreciate their individuality and diversity.

Key Takeaways:

  • Blue jays and bluebirds are two distinct species with different physical traits, behaviors, and habitats.
  • Understanding the differences between these birds can help birdwatchers appreciate their individuality and diversity.
  • Blue jays and bluebirds are both beloved for their beauty and unique characteristics.

Physical Appearance

One of the most obvious differences between blue jays and bluebirds lies in their physical appearance.

Blue Jay Bluebird
Size: 9-12 inches (23-30 cm) Size: 5.5-7 inches (14-18 cm)
Color: Bright blue crest, wings, and tail feathers with white and black markings; grayish-white underparts Color: Bright blue wings, back, and tail feathers with rusty-red breast and white belly
Distinctive features: Large sturdy beaks, crests that can be raised or lowered Distinctive features: Small slender beaks, flat head with rounded body shape

While both birds sport blue feathers, their color patterns and physical build are distinctly different. Blue jays have bright blue crests, wings, and tail feathers with white and black markings, while bluebirds have bright blue wings, backs, and tail feathers with a rusty-red breast and white belly. Blue jays are larger and sturdier, with a large beak and a crest that can be raised or lowered, while bluebirds have a smaller, slender beak and a flat head with a rounded body shape.

Additionally, male and female blue jays look similar, while male bluebirds have brighter and more uniform blue feathers than females.

Behaviors and Habits

Blue jays and bluebirds have distinct behaviors and habits that set them apart from each other. Let’s take a closer look at some of the most notable differences:

Behavior/Habit Blue Jay Bluebird
Feeding Habits Blue jays are omnivores and will eat a variety of foods, including insects, nuts, fruits, and seeds. They will even raid other bird nests for eggs and chicks. Bluebirds are primarily insectivores, and their diet consists of beetles, grasshoppers, and caterpillars. They will also eat fruits and berries during the winter when insects are scarce.
Nesting Behaviors Blue jays are known to be aggressive birds during nesting season. They will defend their nests fiercely and will even attack other birds and animals that come too close. Bluebirds are less aggressive and are known to coexist peacefully with other birds. They prefer nesting in natural cavities or birdhouses and will often reuse the same nest year after year.
Vocalizations Blue jays are highly vocal and have a wide range of calls and songs. They are known for their distinct “jay jay” call and can mimic other bird species and even human voices. Bluebirds have a soft, melodious song that is often described as “cheerful” or “uplifting.” They use their songs to attract mates and defend their territory.
Territoriality Blue jays are highly territorial birds and will defend their territory aggressively. They will chase away other birds and animals that come too close and will even attack their own reflection in windows or mirrors. Bluebirds are less territorial and can often be seen nesting in close proximity to other bluebird pairs. They will defend their nest site from other bird species but are generally peaceful towards other bluebirds.
Migration Patterns Blue jays are non-migratory birds and will typically remain in their breeding territory year-round. However, they may move to lower elevations in the winter to find food. Bluebirds are partially migratory and will move southward in the fall to avoid harsh winter conditions. Some bluebirds may remain in their breeding territory year-round if food is plentiful.

As we can see from this comparison, blue jays and bluebirds have unique behaviors and habits that make them distinct from each other. Understanding these differences can help us appreciate the diversity of bird species and the important roles they play in our ecosystem.

Habitat and Range

Blue jays and bluebirds have different preferences when it comes to habitat and range.

Species Habitat Range
Blue jay Wooded areas, parks, and suburban neighborhoods Found primarily in eastern and central North America, from southern Canada to Florida
Bluebird Open fields, meadows, and rural areas Found across North America, from southern Canada to Mexico

Although their ranges may overlap in some regions, blue jays and bluebirds generally occupy different habitats.

Blue jays are adaptable to a range of environments, from forests to urban areas, as long as there are trees for nesting and perching. They are often seen in backyards and gardens, and their loud calls and bright plumage make them a popular species for birdwatchers.

Bluebirds, on the other hand, prefer open spaces with low shrubs and trees for nesting. They are found in rural areas, meadows, and along the edges of forests. Bluebirds are often associated with farmland and rural landscapes, but they can also be found in suburban parks and golf courses.


After exploring the physical appearance, behaviors and habits, and habitat preferences of blue jays and bluebirds, it’s clear that these two species have several distinct differences that set them apart from each other.

While the blue jay is larger, more aggressive, and has a crest on its head, the bluebird is smaller, more gentle, and has a reddish-brown breast. Blue jays are also known for their loud, raucous calls, while bluebirds have a more melodious song.

When it comes to behavior and habits, blue jays are opportunistic feeders and prefer to nest in deciduous or mixed forests, while bluebirds are insectivores and nest in open country habitats like meadows and fields. Blue jays are also non-migratory, while bluebirds migrate to warmer areas during the winter months.

Finally, our exploration of their habitat preferences and geographic range reveals that while Blue Jays can be found in Canada, the eastern and central United States, and even as far south as Florida, Bluebirds are more common in the central and eastern parts of the United States, as well as in some western states like Arizona and New Mexico.

By understanding these differences, we can appreciate the diversity of bird species and the unique characteristics and adaptations that allow them to thrive in their respective habitats.
