@DavidBrown Took it down, actually I made it private, because it didn't fit with the format of my later videos. Those films taken down will be reshot in a more modern style. In a less professional term, they sucked due to lack of editing skills. A case of choosing quality over quantity. However, in light of this comment, I made it 'Unlisted', and it should be available for viewing as long as someone has the link.
Thanks, Moebelle. Much appreciated. This looks like a very interesting zoo, and your videos show the exhibits in three dimensions in ways that still photos don't.
