Contribute to the Conservation of Shorebirds


Leg Flag Importing

Submit your observation of shorebird leg flags to the BirdMark database.

Shorebirds have been tagged (with leg flags) for over 50 years, enabling long-term study of their health and behaviours across generations and geographic locations.


Data and Photo Galleries

Visit the Data and Photo Gallery links to learn more.

Submitted observations are stored in the BirdMark database. We've generated galleries and reports to demonstrate what we have learned from our data, and invite you to explore them too.



Use your expertise to help us vet submissions in order to improve the accuracy of our BirdMark database.

Our legion of researchers and volunteers submit large volumes of images that capture shorebirds with a leg flag. Sometimes, the imaged shorebird's species or leg flag is unclear.


Help Guides

Visit the Help Guides links for more information.

We've created video tutorials and collated online resources to help inform of the methodologies behind leg flags and shorebird tagging, and how you can contribute your own observations to BirdMark.

Incredible photographs taken by our contributers. Captured are shorebirds with a visible Leg Flag, used to identify an individual and their geolocation.

Who are we at BirdMark

BirdMark was initiated by the Australasian Wader Studies Group (AWSG), Victorian Wader Study Group (VWSG) and Deakin University, and born out of the need to bring together the banding data on shorebirds collected by a legion of volunteers and researchers. While initially focussing on shorebirds banded in Australia, BirdMark assists research and conservation of shorebirds along the entire East-Asian Australasian Flyway (EAAF), collating observations across 37 countries including Australia, New Zealand, China, South Korea, and more.
