slender-billed scimitar-babbler Pomatorhinus superciliaris

Possibly the species to which the moniker of “scimitar-babbler” attaches most fittingly, as this inhabitant of high-altitude evergreen forests has a bill shaped like a curved sword. Predominantly orange-brown, with a gray head and jagged white eyebrow. Easily identified, even if seen only in silhouette; no other babbler in its range has such a long, sharply curved bill. Moves through the lower levels of the forest in large, noisy flocks.
