A real-time, online checklist program, eBird has revolutionized the way that the birding community reports and accesses information about birds. Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird provides rich data sources for basic information on bird abundance and distribution at a variety of spatial and temporal scales.

eBird’s goal is to maximize the utility and accessibility of the vast numbers of bird observations made each year by recreational and professional bird watchers. It is amassing one of the largest and fastest growing biodiversity data resources in existence. For example, in May 2015, participants reported more than 9.5 million bird observations across the world!

eBird Mobile Apps Overview

Over the coming years, eBird will be moving its services onto mobile platforms, including iOS and Android. Currently the eBird Mobile app is focused on data entry in the field, making it easy to record birds as you encounter them while birding, and then submit these observations directly to your eBird account. As the app develops further, we will be bringing in more functionality from eBird: your My eBird stats; the ability to add photos, age/sex information, share lists, etc. Stay tuned for updates on the eBird home page and on this overview page. Also, for more information see our eBird mobile app FAQs.
eBird Mobile

eBird Mobile makes it easy to record the birds you see in the field, and seamlessly link these observations with eBird--a global online database of bird records used by hundreds of thousands of birders around the world. This free resource makes it easy to keep track of what you see, while making your data openly available for scientific research, education, and conservation. eBird Mobile is the only app that passes information directly from iOS and Android devices to your eBird account on the web.
