Chinese Egret’s feeding behaviour.
By T. Ramesh.
Chinese Egret ( Egretta eulophotes) is also known as Swinhoe’s egret & yellow-billed white heron. It occurs along the coast of east Asia from east Russia, through China to Korea and winters in Southeast Asia. This species is a rare migrant to Singapore and it is on globally vulnerable conservation status.
Upon hearing the sighting of this egret at Chek Jawa, I made two visits and was happy to sight this rarity there on 20th March 2020, two hours before the low-tide at 1.30 p.m. It stayed at the tidal mudflats for 3 hours and I had an opportunity to observe and video record its feeding behaviour. Chinese egret feeds mainly on fish, shrimps and small crustaceans. It follows tide-line to feed.
The Chinese egret is an active feeder and moves with lots of energy . It moves quickly around its feeding site to find and chase fish . It showed various feeding techniques as below:-
i) Running rapidly for short distance and stabbing with its bill
ii) Making sudden turns right , left and u-turn and stabbing with its bill
ii) Walking slowly and standing looking for food
iv) Running with wings half-spread and flapped or flicked
I have captured all of these actions in the attached video:
Their indecisive and sudden movements appeared comical and many of us started laughing. Observing this peculiar behaviour of this global rarity was indeed , a rare opportunity !
