The Blue Jay’s unique personality and the affinity for using its own name as a bird call are part of what makes the blue jay so expressive.

Mark Twain, a fan of the beautiful and elegant blue jay, once said, “There’s more to a jay than any other creature. You may call a jay a bird. Well, so he is, in a measure, ’cause he’s got feathers on him and he don’t belong to no church perhaps, but otherwise he’s just as much a human as you and me.”

A passerine bird, the blue jay is native to North America and can also be found through the eastern and central parts of the United States. Some of the populations of this bird are even known to be migratory. The Blue Jay is a bird known to be a forest dweller and is highly adaptable as well as intelligent in nature. They are known to be able to imitate hawk calls and are especially famous for their “jay jay” call.

Blue Jay Scientific Name

The blue jay goes by the scientific name Cyanocitta cristata and belongs to the family Corvidae. It comes from the class of Aves and the kingdom Animalia. They get their name blue “jay” from the noises that they are known to make that sound exactly like it.

There are several subspecies of blue jays – Cyanocitta cristata cyanotephra, Cyanocitta cristata bromia, Cyanocitta cristata, and Cyanocitta cristata semplei. The Cyanocitta cristata cyanotephra is primarily found within the southeastern United States in Nebraska, Kansas, Oklahoma, and some parts of Wyoming and Texas. The Cyanocitta cristata bromia is found in parts of the central United States, though it is also found in the southern region of Canada. While the Cyanocitta cristata cristata is native to the eastern side of the United States, the Cyanocitta cristata semplei exclusively is found in Southern Florida.

Symbolism of a Blue Jay

The symbolism of the blue jay bird is vibrancy, intellect, and clarity. They are known to be songbirds who love singing in their free time and their creativity is well known too. These birds are often used as a totem, but it doesn’t quite have the symbolism that Old World birds do since they are native to the northern hemisphere. Still, in the Sioux, Chinooks, and Coast Salish tribes, it has found a home in many myths and stories.

European folklore has a special place for blue jays as well. Many people believe that the bird is tricky, imitating other creatures and preserving the secret location of its own nest. One story, which is told by Europeans and Americans alike, suggests that the original blue jay was much bigger than the bird known today. As the legend goes, the large Jay was once kept captive by people who used it to help them plow their lands. To avoid ever being entrapped and enslaved again, the bird urged the Great Spirit to make him a fraction of his size. The details of his chest are allegedly the remnants of the marks he received while plowing for humans.

They have also been linked to Great Oak trees for the seeding they perform, leading many Celtic people to see them as a reincarnated soul of the Druids. As a spirit animal, the blue jay stands for longevity in relationships, whether they are of a romantic or platonic nature. Perhaps this is due to their monogamous habits.

The nests are finally readied with the help of moss, twigs, foliage, leaves, and barks. The gestation period in these birds usually lasts from about 16 to 18 days.

The female blue jay lays three to five eggs after which she sits on them for incubating them for a little over two weeks. During this time, she is fed and taken care of by the male blue jay.

After the egg hatches and the newborn is welcomed into the world, it stays in the nest for two months after which the parents and the newborn go stay with the rest of the family for a while. During this time, the male and the female blue jays together take responsibility to feed and take care of the baby.
