How To Recognize A Female Blue Jay From A Male Blue Jay Bird


Observing the patterns of behavior displayed by male and female blue jays is the only way to tell them apart from one another.

You can tell males from females by observing which birds court the other birds (the males court the females) and then which birds brood the eggs.

Males will court the females, while females will tend to the eggs (the female will incubate the eggs). Blue jays are stunning birds that can be found in the eastern and central parts of the United States.

They are distinguished by the brilliant blue color of their feathers and the crest that sits atop their heads. Even though blue jays are quite distinctive, it can be challenging to distinguish between male and female blue jays.

What characteristics distinguish male blue jays from female blue jays and vice versa?

It would be beneficial to know a little bit about the general behavior and characteristics of blue jays to learn how you can identify the females and males of the series.

This would allow you to learn how to tell which members of the series are which.

A Few Facts Regarding Blue Jays:

  • It can be found in various environments, such as urban areas, towns, deciduous forests, and gardens.
  • It consumes a wide variety of foods, but its favorite foods are fruits, nuts, and grains.
  • Produces a unique “Jay! Jay!” sound but is also capable of producing a wide variety of other vocalizations.
  • Produces three to seven eggs at a time when it does so.

Different Varieties Of The Blue Jay

Depending on the classification system, blue jays can be broken up into four or even more subspecies. There are four subspecies of blue jays that are commonly recognized.

These subspecies are the Northern Blue Jay, the Interior Blue Jay, the Florida Blue Jay, and the Coastal Blue Jay.

Physical Traits And Qualities

The length of a blue jay ranges from about 9 to 12 inches (21 to 30 centimeters), and its weight can range from about 13 to 17 inches (34 to 43 inches).

Blue jays are considered to be small to medium-sized birds. The head of the blue jay is adorned with a crest that looks like a crown and is covered in feathers.

The bird’s mood causes these feathers to rearrange themselves in different configurations.

The feathers on a blue jay’s head will bristle in response to fear, the crest will be raised in response to excitement, and it will be lowered when the bird is resting or when it is in the company of other blue jays.

The distinctive blue color of a blue jay’s back feathers, which comes from how their feathers are structured, is one of the bird’s most recognizable characteristics.

Due to the structure of their feathers, certain wavelengths of light are absorbed while others are reflected, causing interference that gives the impression that they are blue.

This phenomenon is referred to as “structural coloration.” The underside of the bird and its face are typically white.


The blue jay inhabits most of the eastern half of the United States and parts of Texas and Canada. It can also be found in a few places in Mexico.

The states located in the Great Plains form the westernmost part of the blue jay’s range.

During the cold months of the year, blue jays native to the northern parts of the United States and Canada might move southward to warmer climates.


The blue jay eats a diverse array of foods to sustain itself. Their beaks were designed primarily for cracking open nuts and seeds, so acorns and other similar foods are among their favorite foods to consume.

They are also willing to consume grain, fruit, and berries without hesitation. Blue jays are omnivores, meaning they will consume insects such as grasshoppers, beetles, caterpillars, and spiders when they have the opportunity.

Blue jays have a reputation for being quite aggressive and will compete fiercely with other species of birds, including jays, grackles, and woodpeckers.

As was just mentioned, blue jays have a reputation for being quite aggressive, a trait also found in other species of birds, such as starlings.

They are also quite intelligent, as evidenced by the fact that they frequently collaborate and communicate with one another to drive off potential rivals or to frighten away potential prey.

Because of the nature of blue jays, their relationships with other bird species can be quite complicated. To protect their territory, they frequently chase away members of other bird species.

People who would rather have a wider variety of bird species in their backyards may view them as a nuisance because of the presence of these animals.

On the other hand, blue jays have been known to drive away larger predators, making the environment safer for other species of small birds to live in.

The blue jay is a curious bird that has been observed to have an unusual fixation on shiny objects such as coins and bottle caps, even going so far as to steal these items and mess around with them.

Blue jays can communicate with one another using a wide range of vocalizations, including a variety of tweeting and chirping sounds.

These sounds also warn one another about potential dangers, such as predators. They are frequently the target of predatory birds such as owls and hawks.

(It can imitate the noise that raptors make to scare away other birds and investigate whether or not raptors are present.)


In contrast to many other birds, blue jays typically form monogamous mating pairs that remain together throughout their lives.

Observing the bird’s behavior while it is engaged in courtship is one of the most reliable methods for distinguishing a female Blue Jay from a male Blue Jay.

Blue jays will typically congregate in small groups of three to ten individuals most of the time. The female takes charge of the flock, and the male birds will immediately take flight in response to any direction she takes them.

As soon as the female has landed, she will remain still and observe the other birds, while the males of the species will bobble their heads back and forth to attract the female’s attention.

The blue jay’s mating season begins in the middle of March and can last as late as July if conditions are favorable. In general, female blue jays will lay between three to eight eggs in their clutches, with an average of four to five eggs being laid.

After a few weeks, the chicks will emerge from these eggs. Observing male and female Blue Jays as they construct their nests is yet another method for telling them apart.

Even though males and females frequently work together to construct practice nests, females take the lead in constructing the actual breeding nest.

In addition, the female is responsible for incubating the eggs most of the time, while the male brings the food to the female.

After approximately 18 to 21 days, the young birds can fly; however, they will continue to remain close to their parents to continue learning from them until the beginning of fall, at which point the young birds will disperse and begin their independent lives.

In conclusion:

Because male and female blue jays have extremely similar appearances, the best way to tell them apart is by observing how they behave.

Keep an eye out for the female bird taking charge of the flock, as the males will follow closely behind her and bobbing their heads to get her attention.

Immediately after the nest has been constructed, the female will begin incubating the eggs, and the male will bring her food.
