Drongo de Ludwig Común Dicrurus ludwigii

Small drongo with a slightly notched tail. Found in open forest, thick woodland, and thickets. Not as bold or conspicuous as the common Fork-tailed Drongo. Often in pairs. Song is an explosive and highly variable mix of whistles, squeals, and rasps. Similar to Velvet-mantled and Fork-tailed drongos, but with a much less forked tail. Very similar to Shining Drongo, but Square-tailed has less glossy plumage, a redder eye, and prefers drier habitats. Distinguished from black-flycatchers by heavier bill and red eye. Upright posture is unlike other all-black mid-sized birds.
