North Am Bird Watching Experts

The eastern bluebird, also known as the Sialia sialis, is a medium-sized songbird found in regions of North America such as southern Canada and eastern parts of the United States. Its appearance consists of a striking combination of bright blue plumage on its back, wings, tail feathers, and an orange or rusty-colored breast and white belly.

The western bluebird, or Sialia Mexicana be found in western parts of North America, including the Pacific Northwest and the Rocky Mountains. Its blue plumage is darker and more vibrant compared to its eastern counterpart, with a striking blue head that sets it apart., is slightly larger and can

Types of bluebirds

  • Eastern
  • Western
  • Mountain

Natural habitat and geographical distribution: The eastern and western bluebirds prefer open areas with scattered trees, such as golf courses, meadows, and farmlands. They can also be found in mountainous regions, where they are known as mountain bluebirds. These birds are not migratory and can be found year-round in their preferred habitats.

Diet and feeding habits: Bluebirds are primarily insectivorous, with insects making up most of their diet. However, during colder months when insects are scarce, they will switch to consuming berries and fruits. They can often be spotted perched on bird feeders for mealworms or suet.

Blue Jays

Blue Jays Bird Watching Experts

The blue jay, scientifically known as Cyanocitta cristata, is a medium-sized songbird with vibrant blue feathers on its head, wings and tail. Unlike the bluebirds, they have a crest of feathers on their heads that can be raised or lowered depending on their mood.

Types of blue jays

  • Eastern
  • Named as the Canadian counterpart of western scrub-jay by AOU in July 2016
  • Western or woodland

Natural habitat and geographical distribution: Blue jays can be found throughout eastern and central North America, from southern Canada to Florida and Texas. They prefer mature forests with tall trees and sparse woodland areas. However, they have also adapted to urban environments and can be found in suburban gardens and parks.

Diet and feeding habits: Blue jays are versatile, feeding on insects, seeds, nuts, fruits, and even small rodents or other birds’ eggs. They are known to store food for later consumption and are occasionally seen at bird feeders.

Comparing Bluebirds vs Blue Jays

Both bluebirds and bluejays are intelligent birds often seen perched on treetops or at bird feeders.

However, there are some notable differences between these two species.

  • Blue plumage: While both birds have “blue” in their name, the shade of blue is quite different. Blue jays have a darker, more vibrant blue plumage, while bluebirds have a more muted shade of blue.
  • Head: The most noticeable difference between the two species is their heads. Blue jays have a crest of feathers on their head that can raise or lower, while bluebirds have a rounder head with no crest.
  • Reproduction: Blue jays are sexually dimorphic, meaning that males and females have different appearances. Male blue jays have a bright blue head, while female blue jays have a duller grayish-blue coloring. On the other hand, both male and female bluebirds have similar plumage with shades of blue on their body and wings.
  • Body shape: Blue jays have a stockier body shape than bluebirds’ more slender and streamlined bodies.
  • Nesting Habits: Blue jays prefer to build their nests on mature trees, typically in the forks of branches. They use various nesting materials such as twigs, pine needles, and grasses. In contrast, bluebirds are cavity nesters and often rely on nesting boxes or natural cavities in trees.
  • Habitat: While both species can be found in North America, blue jays are more commonly found in the eastern parts of the continent while bluebirds can be seen in both eastern and western regions. Blue jays also inhabit a wider range of habitats, including urban areas and golf courses, while bluebirds prefer open woodlands with tall trees. In Central America, bluejays can also be found, whereas bluebirds are not typically seen

Interaction with Humans

Bluebirds: Bluebirds are favourites among bird watchers due to their bright blue plumage and melodic song. They are also known for being intelligent birds that can be easily trained to use bird feeders. However, their population has declined due to habitat loss and competition from other bird species.

Blue Jays: Blue jays are notorious for raiding other birds’ nests, especially during the breeding season. This has led to negative perceptions among some bird enthusiasts. However, blue jays also play an important role in spreading tree seeds by caching food for later consumption.


In conclusion, while bluebirds and blue jays may share similar traits, such as their blue feathers and ability to mimic other bird species, they have distinct physical appearance, behaviour, and habitat differences. Both species play important roles in their ecosystems and are fascinating creatures for bird lovers to observe.

It is important to appreciate the unique characteristics of each species and work towards conserving their populations and habitats for future generations to enjoy. Whether you are a bird watcher, a nature enthusiast, or simply appreciate the beauty of these birds, learning more about them can only enhance your understanding and appreciation of the natural world.
