eBird by Cornell Lab

Record birds while you are out

eBird by Cornell Lab is a field companion for birdwatchers who want to log sightings as they happen. Add species to checklists, record where and when you saw them, and send the observations to your eBird account. It suits beginners building a personal record as well as experienced birders who contribute regular sightings.

Checklists shaped by place

The app uses your location and the time of year to suggest birds you are likely to encounter nearby. Location tools can plot your outings, while map views point to eBird Hotspots in many regions. You can also review life, year, and month lists for a selected area or location, making it easier to see what is missing from your records.

A practical reference in the field

eBird by Cornell Lab includes a worldwide bird taxonomy based on the Clements Checklist. Species names are available in multiple languages and regional forms. Quick-entry tools help reduce typing, and the app can flag sightings that appear unusual for the area. Offline support is useful for trails, wetlands, and other places where a reliable connection is not available.

Built around shared observations

Your records connect with the wider eBird database, where bird observations support education, research, and conservation work. The app is published by the Cornell Lab of Ornithology and sits in the Books & Reference category. It has a 3.97/5 rating from 3,826 reviews and more than 1,000,000 installs, giving it a substantial base of Android users.
