As many birders know, the checklists of the world’s birds are merging and the overall master list (One List To Rule Them All!) is called Avilist. This officially happens sometime in November, 2025. Birds of the World (BOW) is having a 90-minute seminar about it, coming up on 13 November, 2025, 6am Pacific time.

Yes, 6 am our time; that’s to accommodate people from various locales around the world, some of whom may be even more inconvenienced than we SoCal birders.

If you don’t desperately need to see it live and maybe ask a living human being a question, it will very likely be recorded and show up in the BOW library. I don’t know if you must be a paying member of BOW to see it live or recorded. Something may show up on the eBird website, but I haven’t seen any announcements there about it so far, so I’m not holding my breath for that to happen.

But if you want to see it live, you have to register for it here. https://cornell.zoom.us/webinar/register/WN_MyBTMEdCQg6Z_nEcrr7Azg#/registration. If you can’t access that web page, you likely have to be a subscriber to BOW.

According to the BOW announcement page:

Every year, the world’s taxonomic authorities propose a newly restructured avian taxonomy. Soon after the taxonomic changes are settled, our taxonomy team and editors get busy revising accounts so that the Birds of the World website reflects the new eBird/Clements taxonomy.

The 2025 taxonomy updates will be available in Birds of the World, eBird, Merlin, and Macaulay Library in November, 2025. Join us to learn what changed this year!

Featuring:
Dr. Shawn Billerman, Science editor, Birds of the World
Dr. Pamela Rasmussen, Senior research associate – avian systematist, Birds of the World
Marshall Iliff, eBird project leader, taxonomy specialist, common names database manager

Concepts will be intermediate to advanced.
Fun time for all!
