One juvenile BFS, fitted with satellite tracking transmitter and colour rings (S21), came to Deep Bay in early November. Signals of this bird have been collected and these results could show the movement of this bird. In the picture, it clearly shows that this bird likes to stay overnight in Pond 11, Mai Po Nature Reserve, and go to intertidal mudflat in the Deep Bay area (including near the Hong Kong Wetland Park, outside boardwalk birdwatching hide and also to Futian, Shenzhen) presumably for feeding.
Some of these movements have also been recorded by us and submitted to the BFS Record System (
http://bfs.hkbws.org.hk/en-US/sightings). So, both satellite tracking and reports of re-sighting of colour-ringed individuals could help us understand more about local movements and habitat utilisation of BFS in the Deep Bay area.
This bird was fitted with this tracking device and colour rings at the breeding site of South Korea on June 2013.
