Final update from the Grey Plover tracking project.

Adios Charlie!

Just when everybody was anxiously waiting for Charlie to set off from Siberia, it disappeared with no signal sent back since earlier this week. However, we do believe that Charlie has almost certainly set-off on migration and that might have triggered the transmitter to malfunction or the harness to fall off.

This means the end of our Grey Plover satellite tracking project, but we do hope the journey doesn’t end here. If Charlie (or any of our other 3 birds) returns to Roebuck Bay for their non-breeding season, there is a very high chance that they might be re-sighted with their engraved leg-flags on.

After all, we’ve already learnt so much on the migration of Grey Plover in the past 5 months. More research into harness design will be carried out to see if this can be improved as we think this is the prime cause of our loss of transmissions from our five units over a period of only five months. A lot of the data collected is still to be processed and analysed scientifically, so as to document the achievements, challenges and lessons learnt from this project. This information will not only be very useful reference for similar projects, but also advises conservation plan for the species in future.

So, thank you and adios Charlie, we hope to see you again on the flyway!
