Black-rumped Waxbill

The Black-rumped Waxbill is a charming grayish-brown finch known for its bright red bill and matching red eye-stripe. Its English name comes from the dark, blackish patch on its rump. Remarkably hardy and quick to settle in, this species is a great choice for anyone new to keeping finches. It has been kept as a pet bird in Japan since the 1960s, and its compact size and soft, unobtrusive calls make it easy to accommodate in most living spaces. Whether kept alone or in pairs, it tends to settle into a calm daily routine, giving first-time keepers extra peace of mind.

About Black-rumped Waxbill

A hardy, easy-to-tame grayish-brown finch with a red bill and eye-stripe, growing to about 9-10cm. A beginner-friendly species long kept as a pet bird in Japan.

7 things to know before welcoming a Black-rumped Waxbill

  1. 1Cage & Environment

    This active little bird appreciates a cage with enough room to move around and flap freely. Add perches at a few different heights, and keep the room reasonably warm in winter since these birds don't tolerate cold well.

  2. 2A Tame, Easygoing Bird

    Black-rumped Waxbills are notably hardy and tame quickly with regular, gentle handling. Most individuals are calm and unflappable, which makes them approachable even for someone keeping finches for the first time.

  3. 3Basic Diet

    A finch seed mix should form the core of their diet, supplemented with small amounts of leafy greens like komatsuna. Keep a cuttlebone or mineral grit block available at all times to support eggshell and beak health.

  4. 4Housing With Other Birds

    Their generally mild temperament means they're often kept alongside other small finches. That said, they can become more territorial during the breeding season, so watch how any mix of birds gets along and adjust as needed.

  5. 5How Loud Are They?

    Their calls are soft and unobtrusive, which makes them a reasonably comfortable choice even in an apartment. Even so, individual birds vary, and vocalizing can pick up at certain times of day.

  6. 6What to Watch For

    Keep an eye on preening habits and appetite, especially during molting periods. If you notice a lasting change in energy or eating, it's best to consult a vet experienced with birds sooner rather than later.

  7. 7Getting Ready Before Bringing One Home

    Have the basics ready in advance: a cage, perches, and food and water dishes. Once your bird arrives, place it somewhere quiet and low-traffic at first so it can settle in without added stress.
