The Ashy Drongo (Dicrurus leucophaeus) is an agile and highly mobile bird, executing remarkable twists and turns in the air with extreme skill and speed.
With 14 different subspecies, each differing in their distribution and plumage colour, the ashy drongo is also exceedingly variable in its appearance.
All subspecies are marked with a black chin and a dark, velvety band on their front, but differ in the amount of lighter feathers on the face, with some having a full white facial patch and others having simple white eye patches.
This is the subspecies D. l. salangensis, which occurs in the southern and north-eastern part of Vietnam.
