I saw an Eastern Marsh Harrier strike and kill an Avocet at Lok Ma Chau on Friday 8th - the Avocet was swimming and was too slow to rise and evade the harrier which attacked at low level from behind a wooded bund. However the harrier left the avocet floating on the pond - too heavy for it?
Incidentally it was a different EMH.
Seems that leaving the mudflats may not be too good an option for avocets!
