While vacationing on Mackinac Island we stopped by to a place called the Butterfly House. It was kind of cool if you like that sort of thing. Anyhow, they had some birds in there as well with one oddity…an albino zebra finch. I know this isn’t like having one come to your feeder, but still it is rather unique.
