Report leg flag and band resightings

Thank you for contributing to shorebird research studies in the East Asian-Australasian Flyway.  The information you are helping to collect is incredibly valuable for scientific and conservation purposes.

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

The most comprehensive colour marking database in the East Asian-Australasian Flyway

The BirdMark site went live in February 2021. It contains banding and flagging data from the VWSG. It also contains data from the Australasian Wader Studies Group, Global Flyway Network, Northern Territory wader study group and Queensland Wader Study Group, as well as observations from throughout the flyway.

In 4 different languages it offers the possibility to enter and submit your observations both interactively or as a file. Videos on the various ways in which you can do this are included in the site’s “Help Guides”. Feedback on your observations, including a history of the birds that you have observed, will be returned to you within a couple of days of submitting your data (see example feedback).

With the launch of this site 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.

We encourage you to use BirdMark. However, as we go through the transition phase, you can also still send in your leg band and flag sightings to the database operator at

To enable a quick turnaround in processing please provide the following data at a minimum:

  • Species
  • Date of observation
  • Observer name
  • Location name
  • Coordinates (latitude / longitude)
  • Flag colour(s) and flag position on legs (left/right leg, tibia/tarsus)
  • Flag engraving (if any)

Photos can be sent along with the above details as these are a great aid in identifying individual birds. Information on age, plumage etc is welcomed but is not required.
