The Waxbills and Mannikins are tiny little finches similar in size to zebra finches. They have been in the caged bird trade. Almost all birds which have been part of the caged bird trade during the past 150 years, have at some time been released, or escaped in Hawaii.

This Java Sparrow is a larger Estrildid Finch native to SE Asia. It can be found in open grassy areas of lawns and parks, common in Kapi'olani Park. The bird in front is an adult, the one in back is an immature.

Java Sparrows were so common, and inexpensive, I had one, as a caged bird, when I was 12 years old.
