Japanese White-eye
The Japanese White-eye (Zosterops japonica, 暗綠繡眼鳥) is a small passerine bird in the white-eye family. A resident with bright green upperparts, yellow throat and vent with a prominent white eyering. It can be commonly seen in woodland and urban parks in Hong Kong.
They sip the nectar and eat the insects they find among the petals and twigs. Frequently travel in vocal and active flocks.
These photos were taken yesterday (23 Feb. 2020) near the Cotton Tree Drive inside Hong Kong Park which is a great place for viewing flowers and watching birds. I found them moving in swift bouncing flight through the canopy of the Cotton Tree.
