Thanks John,
Regarding the transmitter aerial, yes, BE is carrying a transmitter.
It is a collaboration project with the Chinese Academy of Science to study migration of shorebirds on this EAAFlyway.
At the moment there are 5 Hong Kong Grey Plover (BE, BD, BB, BA and AU) fitted with transmitters in November and January.
All of them are still around Deep Bay area and are gathering very valuable local movement and habitat usage data for us.
More results will be shared later with this forum.
Cheers,
Katherine
