Based on some user emails, I've edited the "If dead, likely cause of death?" field. It remains optional, but many people have opted to use it. The first option is now "Unknown," and the last is "Other," which is meant to imply that the cause of death is known but not listed. I hope that improves things.

A change was made to the input options for the group a few months ago that I was not responsible for. Since I am the only admin/editor/curator for this group, I can only assume that some larger system changes made by iNat had some effect on this group.
