The Ultimate Pet Bird

The Budgerigar (Melopsittacus undulatus), often called a budgie or parakeet, is originally from Australia and is undoubtedly the most widespread and beloved pet bird worldwide. Small, affordable, intelligent, and with a cheerful disposition, it has everything to please. Behind its constant chirping lies a social animal that can form very strong bonds with its owner. This complete guide will help you learn everything about this feathered marvel.

Identifying a Budgie: Colors and Sex

While the wild form is green, decades of selective breeding have produced an incredible palette of colors (mutations).

Colors (Mutations)

You can find blue, yellow (lutino), white (albino), violet, grey, and many other combinations of budgies. The black "undulated" or scalloped markings on its head and wings gave it its name and are present in most varieties.

Male or Female? Check the Cere!

Distinguishing the sex of an adult budgie is simple: just look at the **cere**, the fleshy part right above the beak.

  • In adult males: The cere is a uniform, bright blue.
  • In adult females: The cere is beige, pinkish, or brown (often crusty during breeding season).
In young birds and certain mutations (like albino), telling them apart is more complex.

Song and Vocalizations: The Budgie "Chatter"

The budgie isn't a great singer in a melodic sense, but it is very talkative! Its repertoire consists of a variety of chirps, whistles, and small squawks. A soft, continuous song is often a sign of a happy, content bird. Some individuals, especially males, are capable of mimicking words and sounds from their environment.

Behavior and Intelligence

The budgerigar is a very social and gregarious bird. In the wild, it lives in huge flocks. This is why it is often recommended to get at least two if you are not home much. If kept alone, a budgie will require a lot of attention and interaction to avoid loneliness and boredom. It's a very intelligent bird, capable of learning tricks and solving small problems.

Budgerigar vs. Cockatiel: Which to Choose?

This is a major dilemma for many prospective bird owners. Both are excellent pets but have different personalities.

Feature Budgerigar (Budgie) Cockatiel
Size Small (approx. 7 inches) Medium (approx. 12 inches including crest)
Noise Level Constant chattering and chirping, but not very loud Melodious whistling, but can produce loud contact calls
Temperament Energetic, curious, very active Calmer, cuddly, often very attached to its human
Talking Ability Good, can learn a large vocabulary Limited, mainly mimics whistles and melodies

Care Tips and the Price of a Budgie

Cage and Diet

Provide the largest cage possible, wider than it is tall, to allow for short flights. The diet should be varied: a high-quality seed mix, formulated pellets, and fresh fruits and vegetables (like carrots, broccoli, apples) given regularly.

What is the Price of a Budgie?

The price of a budgie is very affordable, which contributes to its popularity.

  • Price of the Bird: Expect to pay between $15 and $35 at a pet store or from a breeder. Rarer mutations can be slightly more expensive.
  • Equipment Cost: Don't forget the initial budget for the cage ($50 to $150), toys, food, and a check-up visit with an avian veterinarian.
The purchase price is low, but the commitment is long-term!
