Dark-sided Thrush Zoothera marginata

A dark sooty thrush with an unusually long bill. Dark brown overall with a pale crescent behind the ear and weak white spotting on the underparts. More uniformly dark than other similar brown thrushes in the region. Forages quietly in dense undergrowth, probing about with its long bill near water and rocky outcrops. Larger Long-billed Thrush has a much longer bill, a darker face, and is grayer overall. Gives quiet ghostly whistles which trail off quietly.
