At a glance the quick version
Looks how to spot one
Feathered; large, sturdy finch with a heavy red bill
A plump, smart-looking bird about the size of a house sparrow. The normal form has a soft pearl-grey body, a pinkish belly, a jet-black head and tail, and bright white cheeks, set off by a thick rosy-red bill and a red ring around each eye. Domestic breeding has produced several other colours, including an all-white form.12
Personality what they are like
Java sparrows are calm and gregarious. They like to sit pressed together, preen each other and splash in the bath. Their size can unsettle very small, shy finches, so they are best kept with their own kind or with bolder birds.21
Daily activity how busy a day looks
Active birds that need room to fly. A flight of at least about 120 cm long is recommended, and an aviary is ideal for a group.2
Grooming and care the hands-on bits
Self-grooming and big fans of bathing, so a daily bath dish is a good idea.2
Home where they are happiest
A long flight cage (about 120 cm or more) or aviary with several perches, nest boxes for breeding pairs and a bath dish.2
Food basics what goes in the bowl
A parakeet-style seed mix rich in white proso millet, with oats, paddy rice, greens and egg food. Mealworms and extra egg food help when they are raising chicks.2
Company who they like around
Highly social and happiest in pairs or groups; colony living also encourages breeding.2
The story where it all began
Linnaeus described the Java sparrow in 1758, and its scientific name means 'rice eater'. It became a popular cage bird in China during the Ming dynasty and in Japan from the 1600s, where it often appears in paintings and prints. It was also very popular in the USA around the late 1960s and early 1970s.1
