The Cornell Lab launched BOW in '20 with a central mission: to build a comprehensive, global knowledgebase of avian life histories and data resources to support scientific research and conservation. Many new initiatives have taken root since then! Read more.

Fantastic!

Great to hear!

Please add Birds of the World? We sent two reps to the conference.

Who is in Wales at the European Ornithological Congress #EOU2025 this week? We are! Please stop by the booth and see Shawn and Nick and ask about the exciting things happening with Birds of the World and our partner network.

Finally, simple additions or corrections to BOW can be submitted to support@birdsoftheworld.org - they will be stored until our team has the time to review them.

BOW is truly a collaborative science project. Thanks for caring enough to inquire!

Our global contributor network is growing! More than 2200 contributors so far. Here is information on how to contribute:
birdsoftheworld.org/bow/support/...

The BOW maps you mention may be under revision, or pegged for future update. Submit your bird observations via Bird to ensure consideration for future revisions. And, if you are passionate about science and sharing your knowledge perhaps you'd like to contribute?

You'll note BOW profiles are ALSO integrated with eBird maps. These maps depict frequency of occurrence based on eBird observational data as 100 or 20km grids. birdsoftheworld.org/bow/content/...

The "rare" designation is set by the eBird team using many factors. On Birds of the World, basic range maps are curated from multiple data sources including eBird. They are static-not automatically revised until the next time the account is revised (i.e., only humans make the range determination).

Birds of the World is made possible by 1000s of researchers, authors, and org. partners dedicated to advancing our understanding of birds and ensuring their conservation. Today, we spotlighted one of those authors, Vicente Pantoja-Maggi from Chile. Meet Vicente! birdsoftheworld.org/bow/news/con...

Any members of the American Ornithological Society at this year's meeting? Please stop by our booth and say hi to Maria, Nicole, and Nati. Some exciting research going on! #AOS2025

It is important that people understand that only building engineering prevented this being a wholesale slaughter of dedicated public servants.

In this morning's #AOS25 plenary session, we paused to celebrate, honor & remember our departed friends & colleagues in our In Memoriam tribute. Please join us in honoring these individuals & their contributions to the field of #ornithology.
