Padda oryzivora
(Java Sparrow)
Overview:
Conservation Status
Population Analysis
- For the 54,687 species in the Class Aves (Birds), we average 143.07 observations each in our database; for the Java Sparrow, we have 36,120 observations. Compared to other species in this Class, this species is extremely common.
- A two-sample t-test can be used to determine whether the trend in observations of the Java Sparrow is the same as the trend in observations of Aves. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.

Justification
The popularity of this finch as a cage-bird has resulted (and unless stringent action is taken, will continue to result) in a rapid decline in its population and range as a consequence of intense trapping activity, such that it qualifies as Vulnerable.
