“While some Java Sparrows (Lonchura oryzivora) were in courtship and others were building nests, some had young that had fledged (above). 

“Wells (2007) states that fledging brood sizes are unreported.

    The Java Sparrow is common in aviculture and is known to be prolific. In aviaries, clutches of four to six are the norm, but more have been known.
    However, it would be expected that survival rates are not so good in the wild, and not all the babies that hatched grew up to reach the fledgling stage.
    Alternatively, the fledgling stage is one of the most vulnerable in the course of a bird’s life, and some could have been eaten by predators on their first outing.
