Answer: Yes, there are finches in Hawaii. You'll find both the house finch and the koa finch. As for your hibiscus - you didn't say whether you're dealing with an insect or disease. I'm afraid your description of the problem didn't give us many clues to go on. If you submit another question to this forum, detailing where your hibiscus is planted (sun or shade) and exactly what the problem looks like, we can help.
