Колумбийская муравьянка Cercomacroides parkeri

Fairly small, long-tailed, plain antbird endemic to Colombia. Male is all gray with some white fringes on the wing feathers and tip of tail. Female is dull brown above and cinnamon below without wing or tail markings. Found in understory of subtropical forest and edge, where pairs are usually quite skulky and difficult to see. Very similar to Dusky Antbird, but Parker’s is found at higher elevations, around 1,100–1,800 m, and has very different song.
