The likely reason you didn't get a reply when you asked about a Species list last week is because Ueno is a pretty large zoo and a complete list probably isn't publicly available. I have visited, but it is a few years ago and I don't have the time (or memory) to write a list that would have hundreds of entries. There is a list globalspecies.org but it is neither entirely accurate nor up to date.
