Nominate adults have a chestnut crown, blackish brown shoulders and upper back with whitish buff streaks, and bright reddish brown lower back and rump. Their tails are reddish with blackish brown barring. They have a faint supercilium that is a bit lighter than the rest of the gray-brown face.

The juvenile's head is dark gray-brown with no supercilium, a buff nape, and less streaking on the back than the adult.<p>C. a. hernandezi is much more whitish on its underparts than the nominate, rather than buffy. It wings are longer, its tail shorter, and its bill both heavier and longer.

Taxonomie

Apolinar's wren has two subspecies, the nominate Cistothorus apolinari apolinari and C. a. hernandezi. The latter was described in 2002 and has been suggested to be a separate species. Apolinar's wren, grass wren (C. platensis), and Mérida wren (C. meridae) form a superspecies.<p>The common and scientific names of Apolinar's wren commemorate the Colombian monk Brother Apolinar Maria (1877–1949) who was also an ornithologist. Its Spanish common name is cucarachero de pantano (literally, swamp cockroach hunter).

Verbreitung und Lebensraum

The nominate Apolinar's wren is found in the Andes of Colombia's Cundinamarca and Boyacá Departments. It inhabits marshes and lake-edge vegetation, especially those with Typha cattails and Scirpus bullrushes. In elevation it is generally found between 2,500 and 3,000 m (8,200 and 9,800 ft) though it also occurs at one site with an elevation of 3,015 m (9,892 ft).<p>C. a. hernandezi is restricted to the Sumapaz Massif, south of Bogotá in Cundinamarca. It inhabits very different terrain, boggy páramo at elevations between 3,800 and 3,900 m (12,500 and 12,800 ft). It favors páramo with the shrubs Diplostephium revolutum or Espeletia grandiflora and requires Chusquea tessellata dwarf bamboo for nesting.
