drongo kouřový Dicrurus leucophaeus

A slim, medium-sized drongo with bright red eyes and gray plumage that is almost black in the western parts of its range and quite pale in the eastern parts of its range; eastern birds also often have an oval-shaped pale facial patch. It has a long slim tail with a deep fork. Common in wooded habitats where it sallies for insects and aggressively chases other birds that may compete for food or nectar. Most birds migrate south every winter. Similar to Black Drongo, but slimmer and usually in different habitats. Calls include harsh and sweet notes, and can mimic some bird species poorly.
