Meet the silver diamond firetail, a rare variety of native Australian finch that looks like a Christmas angel with flames spilling from beneath its robes. Only the most experienced breeders can reliably produce this variety of the diamond firetail (Stagonopleura guttata), selecting parents that carry the recessive genes that give rise to this almost pearlescent plumage.

1 | 11This little cute birds look like in the wild. Endemic to the southeast of Australia, ranging from the Carnarvon Ranges in Queensland to the Eyre Peninsula and Kangaroo Island in South Australia, the diamond firetail grows to 10-12 cm and weighs 17 grams, which is positively gargantuan when you compare it to the mini emu-wren, at just 4 grams. It’s one of three firetail finches from the genus Stagonopleura, all of which are endemic to Australia.

5 | 11Australia’s firetail finches are not technically classified as threatened, but their numbers are declining, and things like habitat loss, feral cats, and other native birds such as the pied currawong are serious threats. The good news is there are active measures being taken to ensure their numbers don’t continue to dip to dangerous levels.

7 | 11Pairing Diamond Firetail finches poses several challenges. First of all, males and females look very much alike. Even though there are some slight differences – those may not be noticeable, especially in young birds. Males are most easily identified by their courtship displays and their songs. Some breeders suggest observing these finches for a while and choosing a pair with voices that are the most different.

9 | 11Even though Diamond Sparrows could start breeding when they are as young as 5 or 6 months old, it is best to discourage that until they are 10 months or a year old to minimize the risk of egg binding in young females. Provided sufficient space is available for all, Diamond Firetails usually do well in mixed aviaries, as they usually get along well with finches of their own size, such Chestnut-breasted Finches, Java Finches, Red-headed / Paradise or Aberdeen Finches, Golden Song Sparrows, Cutthroats, Zebra or Orange-breasted Waxbills, Cordon Bleus, Red Strawberries, Long-tailed Grassfinches and Chaffinches. It is always important to watch birds for compatibility for some time after they have been placed into a communal aviary to see how they get along and remove those that get either too stressed or those that are bullying the other occupants. Even though these finches can be housed in cages, they are prone to obesity if they don’t have the opportunity to exercise / fly every day. They also tend to stress out when confined in small spaces, which will weaken their immune system and lower their productivity (as far as breeding is concerned). A large, planted flight / aviary is preferable. However, pairs may need to be separated when they are in breeding mode to avoid aggression towards other birds. Breeding cages should be at least 24 inches (0.6 meters) long.

11 | 11Mutations: In captivity, several attractive mutations have been produced. Yellow Diamond Firetail Finch – The areas on the tail that are red in the normal plumaged bird, are yellowy-orange in the Yellow Diamond. Silver Diamond – plumage mostly a silvery white, paler below. The rump is a lighter red. Pied Diamond with splashes of white. Some argue that these plumage differences may be caused by age rather than being a genuine mutation. However, pied mutations are common amongst many finch species and are accepted by most as a genuine mutation. White Diamond is generally not long-lived.
