23 fun facts about Blue Jays

1. One of Blue Jays’ favorite foods is acorns.

Blue Jays typically live on the edge of forests, and they enjoy acorns tremendously, among other seeds and nuts. They are found near oak trees a lot because of their interest in eating the acorns.

2. Blue Jays aren’t actually blue.

Blue Jays are identifiable by the crest on their heads and their blue, white, and black plumage. The dark pigment in their feathers is melanin. A trick of the light causes the blue color in their feathers. Scattering light through modified cells on their feather barbs’ surface makes their feathers appear to be blue.

3. Blue Jays are omnivores.

While Blue Jays eat mostly seeds, berries, and nuts, they occasionally enjoy eating insects as well.

4. Female and male Blue Jays look the same.

This is a rare characteristic among birds, and it is called sexual monomorphism, meaning the males and females look the same. Other species of birds have males and females that look very different, which is called sexual dimorphism. With male and female Blue Jays having similar plumage, it’s difficult to tell them apart. However, male Blue Jays are slightly larger.

5. Blue Jays live a long time.

On average, Blue Jays live about five to seven years, but the oldest known Blue Jay lived for at least 26 years and 11 months.

6. The Blue Jay is not a state bird.

Seven US states claim the Northern Cardinal as their state bird, but the Blue Jay is not recognized as a state bird in any US state. However, they are the mascot of a Major League Baseball Team, the Toronto Blue Jays.

7. Blue Jays act as a natural alarm system for other birds.

Like many small birds, one of the predators of the Blue Jay is the Red-shouldered Hawk. They warn other birds of the hawk’s presence by imitating the sound of the hawk when they see one.

8. Blue Jays make a lot of sounds.

These intelligent birds like to chatter a lot. They can imitate the sounds of predators, and otherwise, their sounds range from lovely chirps in the morning to loud and obnoxious squawks. It used to be a jay referred to a person who was a chatterbox and liked to dominate the conversation, so Blue Jays definitely live up to their name.

9. Blue Jays fly slowly.

In comparison to other birds, Blue Jays fly quite slowly at 20 to 25 miles per hour. Ducks can fly at about 60 miles per hour, so in comparison, Blue Jays’ flight is leisurely.

10. Blue Jays are very intelligent.

In captivity, Blue Jays have been seen to use tools to get food, such as using scraps of newspaper or sticks to bring food closer to them from outside their cages, and they have also been seen manipulating locks. Farmers have also observed them waiting until they are done planting to fly down and enjoy the seeds.

11. Blue Jays mate for life.

The mating season typically takes place from mid-March to July. Once a female Blue Jay chooses her mate, they are typically together for life in a monogamous relationship.

12. Blue Jay pairs feed each other to maintain their bond

Because they stay together for life, they must maintain and reinforce their pair bond. One way to do this is by feeding each other. Usually it is the male who offers food to the female. This behavior is most common during the spring and summer, but happens any time of year. Rarely, a female will offer food to the male. This is seen in late summer or fall, and seems to often be in response to other blue jays coming into the pair’s territory. 

13. Blue Jays have interesting social bonds.

Both male and female Blue Jays work together to build a nest for their young, and then when the female is sitting on the eggs, the male will feed and take care of her. Once the young are about 17 to 21 days old, the whole family will then leave the nest together.

14. Blue Jays have mysterious migration patterns.

Some Blue Jays stay all year in one place, and others migrate. Younger Blue Jays are much more apt to migrate than the older ones. Some individual Blue Jays will migrate south one winter but not migrate the next year.

15. Blue Jays are diurnal.

Some birds are nocturnal and active at night, but Blue Jays are active during the day, which means they are diurnal.

16. Blue Jays have many predators.

Adult Blue Jays are preyed on by owls, cats, and hawks, but baby Blue Jays are preyed on by snakes, raccoons, opossums, crows, and squirrels.

17. Blue Jays have strong bills.

Blue Jays, like other birds, use their strong bills for cracking seeds, nuts, and acorns for food.

18. Blue Jays prefer nesting in evergreen trees. 

Any shrub or tree can be used for nesting, but the Blue Jays seem to largely prefer evergreen trees. They build their nests about 3 to 10 meters high in the tree, and the nests are cup-shaped, made out of twigs, moss, bark, cloth, paper, and feathers.

19. Blue Jays are in the same family as the crow.

Blue Jays are members of the corvid family. Corvids are especially intelligent birds, and include crows, ravens, jays and magpies.

20. Blue Jays are expanding where they live.

They are mostly found in the eastern and central parts of the United States, but they are slowly expanding to the Northwest.

21. Blue Jays participate in a practice known as “anting.”

Blue Jays will take ants and wipe them across their feathers, which almost makes it seem like they are bathing in ants. But scientists believe that they do this to make the ants secrete their harmful spray so that when the Blue Jays eat them, the ants are more easily digestible.

22. Blue Jays usually live in small families.

Blue Jays live in small family groups or pairs, but they will gather in large flocks during their mysterious migratory season.

23. For a small bird, Blue Jays have a large wingspan.

The Blue Jay’s wingspan can be anywhere from 13 to 17 inches.


Blue Jays are an incredibly interesting type of bird. From the way they use their voices to how intelligent they are, they are a magnificent bird to have around whether you see them in your back yard or while you’re out on a hike.
