It’s important to note that the term “parakeet” is broadly used to describe small and medium-sized parrots. It’s most commonly associated with budgerigars – or “budgies” – a small parakeet that’s a popular pet. So in our comparisons below we’ll mostly focus on how budgies compare to cockatiels.

Cockatiel vs parakeets: Color Differences

Gray and yellow are the two most common cockatiel colors!


Cockatiels and parakeets come in many colors. The most common color of a cockatiel is grey with a yellow head and orange cheek patches but there are at least 9 variations in color. A popular color for cockatiels is Lutino which is a lovely combination of bright yellow and white. To know if you have a girl or boy cockatiel you need to look at the color of specific parts of their body. These can vary depending on the breed of cockatiel, but for wild cockatiels, males have yellow heads while females have mostly grey heads with some hints of yellow.

Parakeets are a variety of different colors, such as yellow, green, blue, and white. Blue and green are quite common colors. Their faces are generally yellow in color and they have violet cheek patches, they also have six black throat patches. Parakeets have a fleshy spot above their beak called a cere, this is how to tell who is a girl or a boy. On a boy, the cere is royal blue and on a girl, it can range in color between white and pale brown. Like with cockatiels, the number of color mutations that have been bred into parakeets can make determining their sex difficult.

Parakeets appear in more color variants that can include green and blue.

Cockatiel vs parakeets: Diet

Both cockatiel and parakeet diets are very close and they can share the same food if you were to have both types of birds in your home. Cockatiels and parakeets need commercial food made up of grasses, seeds, grains, and dried fruits and vegetables. Fresh vegetables, like lettuce, carrots, and squash, and fruits, like berries, oranges, and bananas are good food choices. Always remove any uneaten fresh food before it spoils. Parakeets and cockatiels appreciate their fresh fruit and veggies being cut up. Budgies shouldn’t get too many high-fat sunflower seeds so they don’t get too chubby. Fresh water should be available at all times.

It’s important to note that some foods should be avoided for both species. For example, chocolate is highly toxic for both parakeets and cockatiels. Other foods that are harmful include fried foods, salty foods, and dairy products.

Cockatiel vs parakeets: Which is larger?

Cockatiels are larger and longer than budgies. On average, cocktails reach a length of about 12 to 14 inches while budgies are only about 7 inches long. It should be noted that other parrots often called “parakeets” such as the princess parrot will grow larger than cockatiels. Budgerigars are on the smaller side of birds known as parakeets.

Cockatiel vs parakeets: Lifespan

Buying a pet bird can be a long-term commitment, so it’s important to understand the lifespan differences between parakeets and cockatiels. Cockatiels generally live 10 to 15 years. Many factors can affect their lifespans, such as whether they have a companion, their enclosure size, and their diet. The oldest recorded cockatiel on record was named Sunshine, and lived to be 32 years old.

On average, parakeets have slightly shorter lifespans than cockatiels. Budgies in particular have one of the shorter lifespans among parakeets, with them living 5 to 10 years when well-cared for. Other parakeet species can live longer, with monk parakeets, golden parakeets, and rose-ringed parakeets all living more than 20 years on average in captivity.

Both cockatiels and parakeets are able to talk. Budgies are more likely to interact with you and speak more often. They both will mimic whistling and other sounds they hear. With cockatiels and budgies, males learn to talk, while the females generally do not.  However, neither species is as talkative as larger parrot species such as Macaws.

Why cockatiels and parakeets can make good pets

Cockatiel and budgies are wonderful uncomplicated pet birds. They are the two smallest parrots who are quiet enough to live in an apartment or condo. These two birds also are much less destructive than larger parrots and they are by far the friendliest and easiest to train.

Budgies and cockatiels are also relatively inexpensive to have as pets and are a great choice for families or seniors. They’re both birds that enjoy companionship, are happy to live together and will chatter and whistle with each other. Budgies appreciate having another budgie to share their home with, however, if you have two they may bond more with each other than with their humans.

Which is the best pet for you? Cockatiel vs parakeet

Which bird is the best pet has a lot to do with the owner’s lifestyle. Parakeets are a good choice for someone who is home a lot and who has the means to provide a good variety of toys for their bird. Parakeets need the stimulation and interactivity that toys provide. Budgies need a good hour of playtime and also time outside of their cage to explore and play. Also, parakeets are noisier than cockatiels because they chatter, whistle, and sing all day long.

Cockatiels are a better choice for someone who prefers their pet to be busy only during certain times of the day and who needs alone time. They are generally ready to play and interact in the morning and in the evening. Cockatiels are a bit quieter than budgies are and appreciate the alone time to contemplate and preen.

Just remember, getting a pet bird if you are largely gone most of the time is a really bad idea. Birds need interaction and affection.

Are Parakeets or Cockatiels Louder?

Parakeets tend to be louder than cockatiels due to their continuous chattering, whistling, and singing throughout the day. For individuals who prefer pets that are active only during specific times and value moments of solitude, cockatiels might be a more suitable choice.

The increased volume of tweeting, which makes cockatiels louder than parakeets, serves a communicative purpose. In the wild, both species maintain constant contact with their fellow birds.

Additionally, budgies typically have quieter voices than both the parakeet and cockatiels due to their smaller size. They tend to chatter more but are generally not as loud unless you have a large flock of them, in which case they might surpass the noise level of a cockatiel.
