  • Temperament:  Best left to experienced breeders.  The Yellow rumped finch can be difficult to breed.  Prefers a large aviary and may benefit from being housed as a colony.  Will hybridize with many other finches including the Chestnut breasted finch.  A single pair can be housed and bred in a large canary cage.  With numbers low in captivity, it is best not to house them with any other species of finch.

Aviary Notes:

Read notes on "Finches - Australian" web page and use in conjunction with details outlined on this page.

Level Of Knowledge Required: Beginner / Intermediate / Advanced / Specialist Breeders Only.

Government Regulations & By-Laws:  Refer to "Government Laws" page.

Housing Requirements:  Click on "Housing birds" web page for general details on the housing of Australian Finches or read on for specific details for this finch.

The Yellow rumped finch will hybridize with many other finch species (Munias) so care must be taken  to avoid this possibility.  Maintaining a genetically pure species is essential.  One pair per aviary is the ideal situation to maximize breeding results.  Can be housed in a planted aviary, small aviary or a large canary style cage.
Some birds may be destructive of live shrubs and plants.

A single pair can be bred in a large canary style breeder cage (or cabinet).

Diet / Feeding:  Click on "Feeding birds" web page for general details on the nutrition of Australian Finches or read on for specific details for this finch.

The Yellow rumped finch requires a good quality finch mix, seeding grasses and some fruits (e.g. apple) and some green leafy vegetables.  Sprouted or soaked seed if available.  Live food is not essential but is beneficial especially during breeding season.  Mealworms are ideal, small crickets and small locusts are also liked.  The best breeding results are generally obtained from the pairs that feed live foods to the young.

Basic seed mix should include Canary seed, White French Millet, Japanese Millet, and Yellow and Red Panicum.

Unlike the Chestnut breasted finch, the Yellow rumped finch, in the wild, rarely feeds on the ground.

Nesting:  A basic overview only.

  • Roosting nest:  No
  • Nesting months:  Varies depending in which Australian State they are being bred.
  • Nesting receptacles:  Prefer to build a nest in bamboo, cane and other reed like grasses.  Will also nest in shrubs or natural dry brush such as tea tree.  Equally it will build a nest in a wide variety of artificial nests including nest boxes and wire baskets.
  • Nest:  Both parents build a large dome shaped nest made of grasses usually without an entrance tunnel.  Nest is lined with soft fine grasses and occasionally feathers.  Dry grasses as well as green grasses will be used in the nest.
  • Who incubates the eggs: Hen during the night, both share during the day.

If large wire baskets are used, it can be loosely filled with nesting material and a cavity pushed into the centre of the material with a hand or fist.  This will leave an entrance hole and the birds can finish the nest building and line the nest.  Before the next clutch has commenced, the old nest can be partially or fully removed, new nest material added to the basket and allow the birds to finish the new clean nest.  Adequate nest material must be available throughout the breeding season.
More details on finch nests and a selection of finch nest photos can be located on the "nests", "finch nests" and "finch nest photos" web pages.  Click on "Up" then "nests" then "finch nests" and "finch nests photos" in the navigation bars.

Breeding: Egg Colour White.  Clutch/s per year 1 or 2, occasionally 3.  Eggs per nest 4 - 6.  Incubation approx 13 - 14 days.  Fledge approx. 21 days.  Independent approx. another  21 - 28 days.  The young may return to the nest for about 7 days.

The Yellow rumped finch is generally a difficult bird to breed in captivity.  Good results can be achieved in a colony in a large planted aviary.  In the wild these birds have a strong social structure and they retain this in the aviary and like to be in a group of Yellow rumped finches.  A single pair can be bred in a large canary style breeder cage.  Young should be removed from the parents after they have become fully independent.

The Yellow rumped finch will hybridize with many other finch species (Munias) so care must be taken  to avoid this possibility.  Maintaining a genetically pure species is essential.

Artificial incubation, hand rearing or fostering will not be covered on this web site.  It is too complex and diverse in nature to be attempted here.  Refer "Specific References" as listed below and "General References" listings.

Health Issues: Refer "Avian Health Issues" web page for information and references.

  • Worming and parasite control and Quarantine requirements of new birds or sick birds are considered to require veterinary advice and therefore not covered on this web site.  Refer above "Avian Health Issues" web page option.
  • Avian medicine is advancing at a rapid pace.  Keep updating your knowledge and skills.
