What's New in Birdathon

2.0.2

March 31, 2026

- Checklists now have the ability to record breeding codes for each observation. The Breeding Code view includes a text description of each code. When saving an eBird report to import into eBird, codes will be included - A button on the Home Screen leads you to a new California Bird Atlas view, specifically designed as a resource in the field to support this five-year breeding bird survey. Three tabs show (1) general information and links, (2) an annotated list of Breeding Bird codes, and (3) a map with CA county boundaries and Atlas blocks that you can display for any county - When saving an eBird report to import into eBird, you now have the option to include GPS coordinates (latitude & longitude) for each observation. Use with caution to avoid endangering sensitive species or nest locations - Also for eBird reports, if a bird was only marked as heard, Birdathon will add "Heard only" to the details field for that species in the eBird checklist - This release also includes several layout improvements, especially for smaller screens, and fixes bugs Additional changes include: - Changed the sort style button to show icons instead of text - Made the species/item count button be much more compact - Settings button now shows gear icon - Added checkmarks to indicate the currently selected item in the sort style menus (both the main view and checklist views) - Separated bottom and top buttons that were merged together due to lack of spacers - Improved the Dark Theme app icon - App now asks if you want to use location services at all appropriate points, such as when tapping the “current location” button on the map - Tweaked the color themes and the color theme picker - Checklist items now extend underneath the bottom buttons - Fixed a bug where indeterminate birds (birds where "?" was tapped) sometimes lost their indeterminate status - Made sure all fields are included when exporting checklists to JSON files

Great for California Bird Atlas

Really love the new features that make contributing to the California Bird Atlas easier, including offline block maps and breeding code summaries. An amazing app!

Birdathon

This is a fantastic app for making lists and keeping track of birds. Outstanding!

My fav

This is literally my favorite birding app I’ve found. I wanted a personal one that wouldn’t force me to create a new list for each sighting, so this is perfect. And all the export options are amazing!

Best mobile field birding app. No contest.

There is so much to love about this app! I have used it daily for over two years. County list, location list, day list. You can name any list you want. I have site lists. I have challenge lists.
In the field it provides accurate sighting information associated with a real time map.
You can pinpoint nest sites. You can pinpoint hawk’s hunting fields. And you can do this while moving.
At the end of a long day, your app will still leave the battery functioning. Can’t do that with ebird.
You can generate first sighting records. Last sighting records. Week by week. Monthly.
If I could ‘fix’ a site for printing summary reports the app would rival the legendary Avisys.
Thanks so much for the wonderful app. And good birding.
