What's New in Birdathon

2.0.3

July 22, 2026

General changes: - Tapping on maps now prioritizes pins over the underlying county boundaries and custom overlays - The duration of a checklist is now consistent wherever it appears (in the statistics at the bottom of a list, in the eBird report, and in the email report). Duration is the difference between the time the checklist was created (which you can adjust) and the time of the last observation or comment made in the checklist - When making an eBird report, if your list is marked as Incidental it will automatically check "No" for "Is this a complete checklist?" Basically just a slightly smoother workflow - On iPads, the Breeding Code view now fills the screen rather than being relegated to one-third of the screen - When tapping a Breeding Code the list automatically scrolls so that the code selected is still visible - The Checklist Statistics view (shown when tapping on the bottom middle button in a checklist) has been cleaned up - Birdathon has been migrated to a scene-based architecture to ensure compatibility with future versions of iOS California Bird Atlas (CBA) Tools updates: - You can now create and name pins on the Atlas Blocks Map. This can be handy for personally marking interesting locations (e.g. nests) you might want to check up on, or marking blocks you plan to bird, etc. Pins are persistent, editable, movable, and deletable. You can copy the latitude & longitude from a pin. You can get Map directions from a pin - The About tab has been significantly refined. There are new and updated links, videos, custom icons, and pointers to new tools including Blockboard and Code Check - “Always Show Current Location” is now on by default for the Atlas Blocks Map - For new installations, the county for displaying Atlas Blocks is now selected automatically based on your current location. If it can't figure out your location (or you don't give it permission), then it defaults to Santa Clara County

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.
