Introducing Estrildid Finches – the Waxbills, Munias, Nuns and Grass Finches

Hello, Frank Indiviglio here. Among the130+ species of the family Estrildidae we find popular cage birds and highly endangered species. Some, such as the gorgeously colored Gouldian Finch, are both - at once rare in the wild yet abundant in the pet trade.
Waxbills and their relatives are often the first finches aviculturists obtain after having gained experience with the hardier zebra or society finches. The black-headed munia and several others are well suited to this role – slightly more sensitive than Zebra Finches, yet robust enough to fare well when given proper care.
Natural History
Estrildid finches range throughout Africa, South and Southeast Asia and Australia and, with the exception of a few Australian species, favor warm climates. They range in size from the 3.3 inch long Fernando Po Oliveback to the Java Sparrow or Rice Bird which, due to its stout build, appears larger than its 5.5 inches.
Conservation
While certain Estrildid finches are among the most numerous birds in their habitats, others, such as the Gouldian and several of the parrot finches, are classified as either vulnerable or endangered by the IUCN. The Black-lored Waxbill, known only from a tiny range in southern Democratic Republic of Congo, has not been seen since 1950, and may be extinct.
Keeping Waxbills
Waxbills, nuns and munias are best housed in large indoor flight cages or, when the weather permits, outdoor aviaries. Warm temperatures are the rule, especially for breeding pairs (they leave the eggs unattended for longer periods than other finches), but healthy birds easily weather occasional exposure to temperatures in the low 50’s (F) if conditions are dry.
A covered nest should be included, even for non-breeders, as many Estrildids roost in nests outside of the breeding season.
Most species are gregarious in the wild, and do well in groups in captivity. Mated pairs, however, are best kept alone.
Diet
Although primarily seed eaters that will thrive on a base diet of high quality finch food, Estrildids need a good bit of protein as well. Egg food and softbill food should always be available. Small live mealworms, waxworms, crickets and other insects are preferred however. Canned insects and anole food (dried flies) are often well-accepted also.
Grit and cuttlebone should be available at all times.
Breeding Estrildid Finches
A number of species, especially the more popularly-kept munias and nuns, will breed readily in captivity if provided with ample room and quiet surroundings. Tri-colored Nuns and other long-kept species are best suited for ones first attempts at breeding Estrildid finches.
All species studied thus far construct covered nests, and many roost in these even when not raising chicks. Protein requirements soar during the breeding season – the provision of additional protein, especially in the form of live insects, is also useful in bringing finches into reproductive condition.

Hello, Frank Indiviglio here. I’m often questioned on the pros and cons of keeping Budgerigars (parakeets) and other parrots singly as opposed to in pairs or groups. Most folks are aware that parrots housed alone tend to form strong bonds to their owners, more so than birds that have others of their own kind to interact with. While this may be true to some extent, there are other considerations. A recent question from a bird owner who planned to give away one of her budgies, in order to make a “better pet” of the other, has prompted me to post some thoughts here.
I’m most impressed by the range of topics addressed by the thousands of posted articles. Parrots take center stage, and the diversity of species covered is truly exceptional, but finch and general interest (disease, training, legislation, conservation) articles are available as well. Recipe exchanges, an array of topic-specific chats and periodic special interest updates add to this amazing site’s value…stop by and see what I mean.

These odd finches do indeed resemble minute quails in body form, coloration and habits. They keep to the ground, even nesting there, and, like their namesakes, explode upward in whirling flight when startled. Quail finches of one or another species inhabit much of Sub-Saharan Africa, usually in association with bogs, swamps and other damp environs.
