I'm no FB user either, but got the tweet from #TrustTomorrow, the charitable trust under Swire Group. On Great Knot Tracking, plse refer to its post of 1 December 2021. Other than with HKBWS, the Trust also engages coastal conservation programmes with such NGOs as TNC HK, Coral Academy, WWF, BLOOM etc.
I am neither its follower nor connected with the above parties, and was just told of such tracking programme.
