Originally developed in 2005, the Birdata website provided an online platform for volunteers and researchers to enter bird survey data and gain feedback about their surveys. This major revamp of Birdata has allowed us to offer this critical conservation tool in the form of a handy, easy-to-use app. The Birdata mobile app is intended to facilitate simple data entry in the field on mobile devices and provides basic reporting statistics.
