Java Sparrow

Kauaʻi evidence

Bishop Museum island checklist (version 2, 2017) lists Kauaʻi status N: naturalized resident or reintroduced population. See original island table. A Hawaiʻi-level record is available, but the species needs a documented Kauaʻi observation before local ecological conclusions are drawn.
