Java Finches, also known as Java Sparrows or Rice Birds, are big, bold and beautiful finches with smooth grey feathers, a black and white head and a thick, rose-pink beak. Once one of the most common finches in Australian aviaries, they’re now much harder to find, which makes them a real prize for finch keepers. This guide from the bird specialists at Birdsville, 684 Botany Road, Alexandria NSW 2015, trading since 1985, covers how to care for Java Finches, from diet and housing to breeding and sexing.

To care for Java Finches, keep them in pairs or small groups in a roomy cage or aviary, feed a quality finch seed mix with crumbles, sprouted seed, greens and fruit, and add egg and biscuit and live food when they’re breeding. Give them a large nest box, as these are the biggest finches most keepers will own.

  • Despite their big beaks, they still need a quality finch seed mix, not a parrot mix.
  • They love sprouted seed, egg and biscuit and live food, especially when raising chicks.
  • They need a large nest, such as a budgie nest box, as a full brood can be up to 7 chicks.
  • Java Finches are very hard to sex by eye, so a DNA test is the surest way.

Where Do Java Finches Come From?

Java Finches are native to the Indonesian islands of Java and Bali, where they live in open grasslands, woodlands, farmland and rice fields. They’re now much rarer in their native homeland than they once were, largely because of trapping and habitat loss, although feral populations live in parts of Asia, Africa and Fiji. Aviary-bred birds are an important way of keeping this lovely finch going.

Do Java Finches Make Good Pets?

Yes. Java Finches are calm, confident and easy to keep, and their size makes them sturdier than many smaller finches. They’re quiet birds with a soft, bell-like song, and the males perform a lovely bouncing dance to court the hens. They’re very social and happiest with company of their own kind, so always keep at least a pair. Like most finches, they’re birds to watch and enjoy rather than handle.

Are Java Finches Available at Birdsville?

Java Finches were once very common in Australian aviaries, but they’ve become much less common over the past few years. Birdsville has them in from time to time, so follow us on Facebook (https://www.facebook.com/BirdsvilleRosebery/), Instagram (https://www.instagram.com/petsvillesydney/) or TikTok (https://www.tiktok.com/@birdsvillepets), or call the store on (02) 9669 1766, to find out when we next have them.

Housing Java Finches

Java Finches are strong flyers and the biggest of the common aviary finches, so give them as much flying space as you can. An outdoor aviary is ideal, with part of it covered to give shelter from rain, wind and hot sun. If you keep them indoors, choose a long flight cage rather than a tall one, as finches fly from side to side, not up and down.

Use natural branch perches at each end so your birds fly the full length, and keep the floor clean and dry. Java Finches love to bathe, so give them a shallow bath, especially in summer.

What Do Java Finches Eat?

Despite their big beaks, Java Finches still need a finch seed mix, not a parrot mix. A good diet combines three things:

  1. Basic Finch Mix mixed with Birdsville Blends Finch and Canary, our biggest selling finch blend
  2. Vetafarm Finch and Budgie Crumbles in a separate dish
  3. Fresh greens, fruit and sprouted seed

Why Birdsville Blends Finch and Canary?

Birdsville Blends Finch and Canary is bagged fresh on site with quality seed and extras such as niger seed, which is very hard to buy on its own in Australia, plus dried vegetables and herbs. Our seed sells so fast it never sits on the shelf. Be wary of many supermarket and chain store mixes, which can be stale or full of cheap filler seed that does little for your birds’ health, especially if you want to breed. If you’re unsure about the seed you’re using, ask our team.

Sprouted Seed

Java Finches love sprouted seed. Mung beans and sunflower make a good addition to your normal finch sprouting mix. Always rinse sprouted seed with Vetafarm Aviclens before feeding, to kill any bacteria. Our Best Bird Treats page (https://birdsville.net.au/bird-treats-tips-and-sprouted-mix/) explains how to sprout seed.

Egg and Biscuit

Java Finches relish egg and biscuit, and will eat loads of it when they’re feeding chicks. Offer a small amount a few times a week, and every day while they’re breeding.

Live Food

During breeding, Java Finches eat a lot of live food, such as mealworms and fly pupae. Live mealworms are available in-store at Birdsville, and Vetafarm Insecta-Pro is an easy insect-based alternative.

Fruit and Veggie Guide

Greens and Vegetables

Seeding grasses, Lebanese cucumber, silverbeet, chickweed and endive.

Fruits

Apple, pear, figs and pawpaw.

Avoid Entirely

Avocado, chocolate, caffeine, alcohol, onion and salty or sugary human food.

Providing Water

Give fresh water every day, and wash the water dish or drinker daily. A separate shallow bath keeps the drinking water cleaner, as Java Finches love to splash.

Calcium and Vitamins

A vitamin supplement in the water helps keep your finches in top condition. We recommend Vetafarm Multivet for every bird. For calcium, give a cuttlebone and a finch grit containing charcoal, shell, baked egg shell, crushed cuttlebone and limestone, and add Vetafarm Calcivet to the water, especially for breeding hens and birds kept indoors. Our How to Make Sure Your Bird Gets Enough Calcium page ([Calcium page link]) explains more.

Common Health Problems in Java Finches

  • Mites and lice: check regularly and treat with a bird-safe spray.
  • Worms: more common in outdoor aviaries, so worm regularly.
  • Egg binding: a hen straining but unable to lay needs an avian vet straight away. Plenty of calcium helps prevent it.
  • Overgrown nails or beak: natural perches help, and Birdsville can trim nails in-store (https://birdsville.net.au/wing-clipping-nail-clipping/).
  • General illness: fluffed feathers, sleeping during the day, sitting on the floor or changes in the droppings mean your bird needs a vet. See our Common Bird Illnesses page (https://birdsville.net.au/common-bird-illnesses/).

Parasite Control

Worm your Java Finches regularly and treat for mites and lice. Quarantine any new bird in a separate area for 4 to 6 weeks before it joins your other birds. When you move birds, or after bringing new birds home, add Vetafarm Spark Liquid to the water for a few days to give them electrolytes and energy.

Breeding Java Finches

The Nest

These large finches need a large nest. A budgie nest box works well, and we wouldn’t recommend anything smaller, as Java Finches can have up to 7 chicks, plus both parents inside at the same time.

Supply a variety of nesting material, such as white feathers, swamp grass and long grass stems, which they like to use for the base of the nest when they start building.

Eggs and Chicks

  • The hen lays around 6 or 7 white eggs.
  • The eggs hatch after about 14 days.
  • The chicks stay in the nest for around 4 weeks before they venture out for the first time.
  • The parents keep feeding the young for a few more weeks while they learn to crack seed for themselves.

While they’re raising chicks, give plenty of egg and biscuit, sprouted seed, live food and calcium.

How Can You Tell if a Java Finch Is Male or Female?

Java Finches are very difficult to sex by eye. If you look closely, the male usually has a larger, more solid upper beak, and the ring of skin around his eye is often a deeper red. Males also sing and do a bouncing courtship dance, while hens don’t sing. These signs aren’t always reliable, so a DNA test is the surest way. DNA Solutions (https://dnasolutions.com.au/animal-dna-testing/) offers bird DNA sexing from a feather sample.

Mixing Java Finches With Other Birds

Java Finches are generally peaceful, but they’re big and confident, and can push smaller finches away from food and nest sites, especially in the breeding season. They’re best kept with other Java Finches or with finches of a similar size. Give them plenty of space, and provide more feeders and nest sites than you have pairs.

Holiday Care and Transport

Finches eat often and can’t go long without food, so have someone check seed, water and fresh food every day while you’re away. When moving your finches, use a small, secure, ventilated carrier, keep them out of heat and never leave them in a parked car.

Java Finch Frequently Asked Questions

What do Java Finches eat?

Java Finches eat a quality finch seed mix, despite their large beaks, along with finch crumbles, sprouted seed, greens and fruit. Birdsville Blends Finch and Canary mixed with Basic Finch Mix makes a great base. Add egg and biscuit and live food such as mealworms, especially when they’re breeding and feeding chicks.

How do you tell a male Java Finch from a female?

Java Finches are hard to sex by eye. Males usually have a larger, more solid upper beak and a deeper red eye ring, and only the males sing and do a bouncing courtship dance. These signs can be unreliable, so a DNA test is the surest way to know whether you have a male or a female.

What size nest box do Java Finches need?

Java Finches need a large nest box, and a budgie nest box is ideal. Anything smaller is too cramped, as a pair can raise up to 7 chicks, with both parents in the nest at the same time. Give them nesting material such as swamp grass, long grass stems and white feathers to build with.

Can Java Finches live with other finches?

Usually, yes, but with care. Java Finches are peaceful but big and confident, and they can bully smaller finches at the feeder or take over nest sites, especially when breeding. They’re best kept with their own kind or with finches of a similar size, in a roomy aviary with plenty of feeders and nest sites.

Are Java Finches hard to find in Australia?

Yes, more than they used to be. Java Finches were once one of the most common aviary finches in Australia, but they’ve become much less common in recent years. Birdsville has them in from time to time, so follow us on social media or call (02) 9669 1766 to find out when they’re next available.

How long do Java Finches live?

With good care, Java Finches commonly live around 7 to 10 years, which is longer than many smaller finches. A quality seed mix with crumbles, fresh food, regular worming, a clean aviary and plenty of space all help your Java Finches live a long, healthy life. Breeding hens need extra calcium and good food to stay in condition.
