Impressively large, roadrunner-like bird of wet foothill rainforest. It’s one of the rarest and most sought-after birds of northwestern Ecuador and western Colombia. Note large size, long tail, chestnut back, and black-and-white scaled underparts. Terrestrial; most likely to be encountered following large swarms of army ants. Sometimes snaps its bill very loudly. Song is a series of soft, very low-pitched, rising notes given at regular intervals.
