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. Visit the Birdata web portal (http://birdata.birdlife.org.au) for extended reporting and data management functionality. Analysis of structured monitoring surveys in Birdata feeds directly into the State of Australia’s Birds report series. These reports are the go-to guide on the status of Australia’s bird populations, designed to inform decision making on land management, and direct conservation and policy that affects Australia’s birds and biodiversity. Can you use it for Birding lists? Yes. Birdata is primarily a tool for structured monitoring, however you can use Birdata to enter and store birding trip lists (e.g. bird lists which are collected over expanded areas without conforming to scientific standards). Please ensure that data such as this is coded as “Bird List” in the “Survey type” field on the details page.
