In 2012, David Bell’s company BirdsInTheHand, LLC, released a mobile app called ‘BirdLog’, on Android and iOS devices. This app revolutionized the way birders recorded information in the field, and was the first and only app to tie directly into your eBird account for data entry. The app became so critical to eBird, that in 2014 the Cornell Lab of Ornithology and David Bell reached an agreement to transfer development and management of the app to the eBird team at Cornell. All current iterations of BirdLog will be sunsetted in the near future, so it is important to make the switch to eBird mobile as soon as possible.

Regular users of BirdLog will find that this app works similarly, with a few key improvements. The initial goal was to make a single, free, global data entry app for eBird. Subsequent iterations of the app will focus on reworking the user interface, making the app available in other languages, allowing breeding code entry and in-app checklist editing, and improving data out functionality. We have also begun development work for Android, and eBird mobile should be available on that platform in the coming months.

What’s new with eBird mobile?

  • Free—eBird mobile is free.

  • Single global version—eBird mobile is available in a single consolidated version that works anywhere on earth.

  • Expanded languages—Offers species common names in many local languages, in parallel with the eBird web site.

  • Four-letter quick entry—based on common name and scientific name for all taxa globally, as on eBird.

  • Show rarities—Rare species are now indicated on the checklist view, prompting observers to provide more detail.

  • Refined start up screen—The ‘home page’ of the app has been reworked from a usability standpoint, making it clear how to get started entering data.

  • Continuity—App updates don’t cause you to lose existing unsubmitted lists or personal locations and start-up is not delayed by taxonomic updates.

  • Data quality improvements—The app more closely matches functionality of eBird web for protocols, and prompts users to be more precise about location plotting.

  • Trip summary—Improved trip summary functionality makes keeping track of your trip list and day list fast and simple.

We look forward to hearing your feedback. Please send comments to '', and share your ideas on how we can improve the app. If you like the app, please rate it favorably on the iTunes store. We hope you enjoy the app!
