Java Sparrow.
(Lonchura oryzivora),
Java Sparrow
(Padda oryzivora)
This bird is native to Indonesia and was introduced first in 1867 and later reintroduced in the late 1960's. It builds nests in tree cavities and under the eves of buildings.
These birds travel in big groups and quarrel amongst themselves. They roost in large dense trees.
Interesting Facts: These small sparrows while abundant in Hawaii are actually becoming endangered in their native range. They are also illegal to keep as pets in some parts of the mainland due to the threat of destroying specific agricultural crops.
Where to find on campus: Open grassy fields during the day. At night they often form communal roosts with Mynas along the median of Maile way between St. John and Gilmore. Original public domain image from Flickr
