Just a quick post today: an ashy drongo from Mt. Davis. This was the first time ever saw one, so I was very happy to get a record shot. These birds migrate south for the winter, so this one is likely passing through. However, there may be more permanent residents elsewhere in Hong Kong, as it is within their breeding range.
The species has a number of subspecies that vary primarily in color throughout their distribution. The ones furthest east in Asia ranging from about Korea to Southeast Asia are more grey colored while those to the west in the Indo-Malayan subcontinent are closer to black.
