Over the years, I’ve built a desktop app, "Yearbirder," for analyzing my eBird sightings. It lets me create lists, charts, graphs, and interactive maps — all filtered however I choose. When I began to photograph birds, I added the ability to view, filter, and manage my photos in the same way.

Yearbirder has developed into an app that I use almost every day. I think other birders might enjoy it too, so I am making it available as a free app. You can find it at http://www.yearbirder.org.

If you enjoy listing and analyzing your sightings, or if you photograph birds, I invite you to check out the website for a fuller description and screenshots of the app.

A few notes about installation: it runs on macOS version 13 or greater, Windows version 10 or greater, and Ubuntu Linux. For macOS, the installation file is signed and notarized by Apple. For Windows, I have yet to register the app with Microsoft, so you'll see two warning screens during installation. You can click through these warnings -- the app is safe.

Yearbirder opens your personal eBird data file, which you download from eBird. The instructions for downloading your data file are on the Yearbirder website. It takes just a few clicks. There is a comprehensive user guide in the app.

If you have issues with the app, please do not email me directly, but rather use the link to report a bug on the website. You can use the same link to request new features.

Lastly, please do not "reply all" to this email or use Cobirds to discuss the app. If you find the app useful, feel free to email me privately.

Enjoy migration!
