The Spoon-billed Sandpiper is one of the rarest birds in the world and consequently is one of the most difficult to find once it leaves its known breeding area for the winter months. Last week, birdwatcher Peter Ericsson photographed one on wetlands at Pak Thale, Thailand. The Sandpiper has been identified as bird ‘AA’, which was hand-reared and released in Chukotka, Russia last summer. This is the first time a hand-reared individual has been identified in the wild by the unique code on its plastic leg flag. Last autumn there were three sightings of Spoon-billed Sandpipers with white leg flags, indicating that they had been reared as part of the headstarting programme, but they were too distant for the codes to be read. Hand-rearing is part of a plan to artificially boost the number of Spoon-billed Sandpipers in the wild while conservationists protect coastal wetlands and stop bird trapping along Asia’s eastern and southern coasts. Also known as headstarting, last year it increased the number of fledglings leaving the birds’ only known breeding grounds by 25%. It also allows conservationists to fit leg flags to the birds. Reported sightings give a measure of the success of different tactics to save the species and could potentially reveal new information about the birds.
Dr Nigel Clark, of the BTO, is a leading wader expert and has been at the centre of efforts to conserve the species. He said: “This sighting is a fantastic bit of news. It shows that headstarting the birds is working and they are successfully migrating and it’s starting to give us more clues that could be useful in future. This is the fifth sighting in Thailand of a bird from the Meinypil’gyno breeding grounds. Only time will tell if that’s a coincidence, so I urge anyone in the region to keep their eyes out for leg flagged birds and report them if they see one.”
Birdwatchers in Asia are asked to particularly look out for and report Spoon-billed Sandpipers with the following markings to firstname.lastname@example.org:
- Any of eight adults marked with light green flags inscribed with two alphanumeric characters on their left legs. These birds were caught and marked in 2013 as wild adults.
- Any of three juveniles with light green flags inscribed with two alphanumeric characters on their right legs. These birds were also caught and marked in 2013 as wild birds.
- Any of the 16 headstarted juveniles from 2013 which have white flags inscribed with two alphanumeric characters on their right leg.
- Any of the 9 headstarted juveniles from 2012 which have light green flags with single alphanumeric character on their right leg.
- Any Spoon-billed Sandpiper with any other marking, as there are a few survivors previous studies.
