The BirdMark portal is specially designed to accept submissions of your resightings of colour marked waders along our flyway.

It supports multiple different languages, offering the possibility for volunteers and researchers to submit observations both interactively or as a file.

We hope to further boost the reporting of marked shorebirds, which is crucial for ongoing conservation and scientific research, informing on the birds’ population dynamics, movements and site use.
Notice

Welcome to the new version of www.BirdMark.net! Aside from it being more secure now, the BirdMark team also hopes you will find the new site more user friendly and interesting. We are looking to expand the BirdMark audience considerably in 2025, with more advanced features, and wider engagement with citizen scientists along the EAA Flyway. We welcome feedback and ideas. For old users: you will have to make a (new) account before you can submit data and use advanced BirdMark features.

Contribute to the Conservation of Shorebirds

BirdMark provides a range of features in our effort to gather much-needed shorebird observations for research.

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 Overviews

Visit the Data and Photo Overview link 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.

Vetting

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 link 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.

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.
