The fork-tailed sunbird (Aethopyga christinae), here in Hong Kong park in late December 2020.
I like this picture, as it has a photobombing honey bee.
The male bird has a metallic blue-green head, dark crimson throat and upper breast as well as decurved bill, with a distinctive trill like call.
it is a Hong Kong resident. Commonly found in woodland and major urban parks.
Breeding season from April to June. Nest is a ball of grass placed in a tree.
