You Drongo.....! These pictures were taken just last week before the rain started in Sai Kung.
NOUN . meaning:
1. any insectivorous songbird of the family Dicruridae, of the Old World tropics, having a glossy black plumage, a forked tail, and a stout bill
2. Australian and New Zealand slang for a foolish person (which i think is based on a racehorse of that name that always came last).
See them in the trees around the orange blossoms, normally in large garrulous flocks.
This here is the Hair-crested Drongo, which is clear from the picture below
