Sorry you lost your pretty finch. I love zebra finches. They have such a soothing, soft beeping song. Used to have a large cage that contained 3 pairs and 3 nests. Even got to watch a clutch be laid and grow up! This was many many years ago. I never did all that maintenance. Can't imagine how the care of such birds could have changed over the years.

Any ideas why your birds died? Little birds don't live a lot of years, maybe 5? If your last one was female, maybe egg-bound?
