Recent Changes

The following includes only newly added species, name changes, newly posted articles, major updates to articles/pages (for example, changes to notes that provide substantial new information/corrections) and new photos. It does not include new photos added to "gallery" pages, minor alterations to data on established pages and correction of typos. Changes in those categories are too numerous to conveniently list.

The most recent changes are at the top and are grouped by month. The links are to the species pages while the comments indicate the nature of the change or give the title of the secondary page that was added or expanded.
