eBird by Cornell Lab

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 the Android device to your eBird account on the web.
