Flock of Budgerigars Breeding with wooden rectangular nest boxes


Budgerigars have two base colors – white (recessive) and yellow (dominant). White based birds are usually mixed with shades of sky-blue, grey, cobalt, mauve and violet whereas the yellow based birds are mixed with shades of green, olive and yellow.

Another distinguishing feature is the small blue patch on their cheeks as well as black markings on their mantle (wings and back).

Budgerigar – Diet:

70% High Quality Seed Mix – Seed mix should have french white millet, hulled oats, pannicum, Japanese millet as well as fortified omega fatty acids, vitamins and minerals. Budgies only eat the contents inside the seed and discard the husk. Most seed mixes already contain grit e.g. oyster shell grit, as it aids with digestion. It is optional to offer grit but should only be offered in small amounts.

Popular brands specializing in budgie diets include ZuPreem, Passwell, Dr Harvey’s or Vetafarm.

20% Fresh Fruit and Vegetables – Chopped apple, carrot, beans, bananas, melons, berries, papaya, peas, corn, broccoli and spinach.

10% Nuts or Millet Spray – Almonds, pistachios, peanuts, walnuts or pecans

Budgerigar – Essentials:

When bringing your little birdie home for the first time, you will need to ensure you have the basics sorted beforehand.

  • Bird Cage – at least 45cm x 45cm x 60cm (W x L x H) – plenty of room for toys and exercise; best to line the cage with newspaper to easily clean their droppings/mess.
  • Cage Cover – any cloth that covers 90% of the cage so the bird can sleep in darkness e.g. blanket
  • Perch – at least two perches, preferably native Australian branches of gum, grevillea, bottle brush, lilly pilly or eucalyptus. Perches provide a form of enrichment and allow the budgie to forage.
  • Toys – 1 or 2 toys to begin with for mental stimulation/entertainment; highly recommend rattling or ringing toys e.g. bells, colorful beads, ladders
  • Bowls – 3x bowls (one for seeds, one for fresh fruit/vegetables and the other for water); your bird might use the water bowl to bath too, that’s completely fine!

Budgerigar – Behavior:

  • Socialization: Budgie’s are highly affectionate and playful birds. They are regularly seen preening other flock members, so it’s best to keep them as pets as a group of 2 or more. They require very little maintenance and perfect for beginner pets.

  • Vocalization: Not too loud however chatterbox birds that chirp and click. With the right amount of patience, budgies can be taught to talk, whistle and perform tricks.

Budgerigar – Breeding:

Budgies reach sexual maturity at approx. 5 months of age but should ideally start breeding at 10 months. You can easily distinguish a budgies gender due to their dimorphic nature – males have a blue or pink cere whereas females are brown/tan. Young budgies all have pink cere so the dimorphic color variation is only evident after 8 months of age.
