Cinnamon Cockatiel: Learn All About This Unusual Color Mutation

Wild cockatiels are typically grey, white, and yellow with bright orange cheek patches. But captive-bred cockatiels display a far broader spectrum of colors and patterns.

Cinnamon is one such variation on the normal grey cockatiel coloration or mutation.

As cockatiel breeders learn more about avian genetics, even more colors and patterns are being developed. So while the cinnamon cockatiel used to be considered a rare mutation, it is much more common and recognizable today.

In this article, learn all about the cinnamon cockatiel and the intriguing genetics that combine to produce this lovely and subtle coloration.

Cinnamon Cockatiel

A cinnamon cockatiel is a term used to describe a specific color mutation. Cinnamon in this context actually describes a variation of normal grey that looks more silver with a brown hue.

Like all cockatiel color mutations, cinnamon describes a color spectrum from light to dark. The important constant is the silver-brown tone of the feathers.

What Is a Cinnamon Cockatiel

To understand the difference between a normal grey cockatiel and a cinnamon cockatiel mutation, it can help to first understand what breeders mean by normal grey coloration.

Normal grey (sometimes called simply “normal”) is the color of wild cockatiels.

As Feisty Feathers breeder explains, this means normal grey is the color pattern against which all other variations, or mutations, are compared.

Normal grey cockatiel description

Normal grey is a dark grey color that is closer to black than to white on the spectrum. The normal grey color is typically found on the chest and body, inner wings, tail, and, in mature adult female cockatiels, on the cheek patches.

The outer wings are pure white. The cheeks are yellow and the cheek patches are bright orange.

Now that you have this visual image in your mind, let’s look at how this changes in a cinnamon cockatiel.

The main difference between a normal grey cockatiel and a cinnamon cockatiel is the color on the chest, body, inner wings, tail, and, for adult female cockatiels, on the cheek patches.

The dark grey changes to a lighter silvery-brown color. This color may get darker or lighter as the bird grows up.

In some cases, as KM Breeding aviary describes it, cinnamon actually looks more like a traditional brown color.

NOTE: Sometimes the terms cinnamon and fallow are used interchangeably. But these are not the same color mutations. Fallow typically has a more yellow tone to the brown and may have red-appearing eyes.

In the next section, we will take a closer look at the kind of genetics that have to be present to turn normal grey into a cinnamon cockatiel.

What Is a Cockatiel Mutation?

The word mutation can sound kind of scary to many people because it can be associated with heritable health issues.

But not all mutations are bad.

As Genetic Lessons points out, a mutation is essentially just a change in a gene. Some gene changes may only result in a change in how a color pigment gets expressed, or shows up, on an animal.

Where things can start to get dangerous is if a breeding program gets so focused on producing a certain color mutation that the breeder starts breeding related birds together.

This narrows the gene pool and can potentially promote minor or more serious health issues.

Because of this, anytime you are deciding where to purchase your cockatiel, you always want to research the breeder’s reputation to be sure their birds are healthy and friendly, and long-lived.

Many cockatiels are relinquished to shelters because their owners don’t have time to train or care for their birds. If you decide to rescue a cinnamon cockatiel, you may not know anything about its breeder or parents.

But you can make sure your avian veterinarian examines the bird before you make a commitment. This way, you can simply verify that the bird you want to adopt is in good overall health.

So now let’s move on to learning more about the kind of deliberate cockatiel breeding program that is required to produce a cinnamon cockatiel.

Learn the Basics of Cockatiel Color Genetics

As Multiscope Hot Spot for Birds outlines, there are three main types of cockatiel color patterns or genetic mutations.

These are sex-linked, recessive, and dominant.

This is important to know if you plan to breed cockatiels or you simply want to verify that the breeder you get your bird from understands cockatiel color genetics and is breeding healthy birds.

Cinnamon cockatiels belong to the sex-linked mutation category.

What on earth does this mean?

Let’s start by briefly defining each category so you can learn the differences.

Dominant cockatiel color mutation

Dominant color mutations mean only one parent bird needs to contribute the genes in order for a chick to have that color.

Recessive cockatiel color mutation

Recessive color mutations have the exact opposite requirements. Both parent birds must contribute the correct gene in order for a chick to have that color.

Sex-linked cockatiel color mutation

Sex-linked cockatiel color mutation breeding is actually the most challenging kind of breeding program, as Talk Cockatiels Forum explains.

In birds, females carry what is essential “XY” genes and males carry “XX” genes (you probably already noticed that it is just the opposite for humans).

The term sex-linked is important here because, in the case of a mutation like cinnamon, it is the female who will potentially only carry one copy of the correct gene, while the male will potentially carry two copies of the correct gene.

The gene mutation that causes a cinnamon cockatiel color mutation is always found on the X chromosome – never on the Y chromosome.

This is very important to know for two reasons.

First, the female cockatiel must show cinnamon coloration. If the female cockatiel is not cinnamon, this means she does not have the correct gene at all.

Second, the male cockatiel does not have to show cinnamon coloration. However, the male cockatiel must be split to the correct gene, which means the male carries it on one of his X genes, in order to produce cinnamon cockatiel chicks.

In summary, if you want to breed cinnamon cockatiel chicks, you must select a cinnamon cockatiel female and a male cockatiel that shows the cinnamon coloration or carries it (“split to”) on at least one of his X chromosomes.

But how can you know if the male cockatiel has the correct gene if you can’t see the cinnamon color on his feathers?

This is what can make cockatiel color genetics so complicated!

Genetic Calculator 1.3 Cockatiels gives you a better visual idea of the type of calculations breeders often have to make to figure out what color chicks a breeding pair might produce.

Possible Outcomes When Breeding Cinnamon Cockatiels

If you know the genetic history of your breeding pair, breeding cinnamon cockatiels becomes easier.

But if you are not sure about the male cockatiel’s genetic history, you could be in for some surprises when the eggs start to hatch.

As Talk Cockatiels Forum outlines, there are several different possible outcomes when you are breeding for the cinnamon cockatiel color mutation and you are not sure about the male cockatiel’s genetic history.

Sex-linked female cockatiel plus sex-linked male cockatiel pair

The first happy outcome is that both the female bird and the male bird carry the correct genetic mutation for cinnamon. In this case, all of the chicks will grow up to be cinnamon cockatiels.

Here, the female cockatiel chicks will be visually cinnamon-colored and so will the males.

Normal female cockatiel plus sex-linked male cockatiel pair

Remember how we said earlier that a female cockatiel has to be visually cinnamon in order for the chicks to be cinnamon?

This is where this fact starts to become important.

If the female cockatiel is not visually cinnamon, the pair cannot produce a full clutch of visually cinnamon chicks.

The pair can produce up to half a clutch of visually cinnamon chicks and these will be females. The males will be split for the cinnamon mutation – meaning that one of their X chromosomes carries the mutation – but will not appear cinnamon visually.

Normal male cockatiel plus sex-linked female cockatiel

In this third outcome, even if the female is visually cinnamon, the male bird is not carrying the required gene to create visually cinnamon cockatiel chicks.

The chicks that are female will not be cinnamon. The chicks that are male will be split to the cinnamon mutation. Here again, this means the males will carry the correct gene but will not look cinnamon.

Knowing how complicated it can get to breed cinnamon cockatiels, you may now appreciate your cinnamon bird even more!
