How long do Java Sparrows live?
Java sparrows typically live 5-10 years in captivity with good care.
What do Java Sparrows eat?
Feed a quality finch/grass seed mix with daily greens, a little egg food, and cuttlebone; avoid avocado and chocolate. Fresh water daily. They are robust but benefit from greens and calcium, especially when breeding.
Java Sparrow cage and daily life
Keep a pair or flock in a flight cage at least 24 x 18 x 24 inches (60 x 45 x 60 cm), bar spacing 3/8-1/2 inch, with perches, a shallow bath, and company. They need room to fly and dislike isolation. Keep away from kitchens (Teflon/PTFE fumes are lethal).
Common mistakes with Java Sparrows
Common errors are keeping one bird alone, too-wide or too-narrow bar spacing, and seed-only diets without greens. Nonstick-fume exposure and owning them where banned (confiscation risk) are other issues.
Beginner mistakes to avoid
- Keeping a single java sparrow, which causes chronic stress.
- Using incorrect bar spacing for the bird's size.
- Feeding seed only without greens or calcium, causing deficiency.
- Keeping them where they are illegal, risking confiscation, or exposing to Teflon/PTFE fumes.
