Little Forktail

The little forktail is a bird of mountain streams, waterfalls and small shaded forest puddles, breeding between 1,200 and 3,700m. The specific name commemorates Dr John Scouler of Glasgow. The sexes are alike, black above with a white forehead, a white band in the wings extending across the lower back, a small black rump patch and a short, slightly forked tail with white in the outer feathers (Wikipedia, general species account).

It has a black throat and is white below, and constantly wags and flicks its tail, occasionally launching short sallies. Solitary or in pairs, it forages energetically on moss-covered, wet slippery rocks, feeding primarily on aquatic insects and plunging underwater to pursue prey. It is generally silent, apart from a rarely uttered sharp 'TZitTzit' call. The source read does not name Bhutan.
